Yes, tanzanite can chip or crack if it receives a strong impact. With a hardness of approximately 6 to 7 on the Mohs scale, fair-to-poor toughness, and a natural cleavage property, tanzanite requires more careful handling than harder and tougher gemstones such as sapphire or diamond. However, this does not mean tanzanite is unsuitable for jewelry. Choosing a protective setting, avoiding hard knocks, and following proper care practices can help reduce the risk of damage.
Whether you already own a beautiful tanzanite gemstone or are planning to purchase a tanzanite ring, understanding its durability is essential. You may be wondering: Does tanzanite scratch easily? Can it break during everyday activities? What happens if your tanzanite has already chipped?
In this guide, we answer these questions and explain how to protect, clean, and care for tanzanite jewelry without compromising its natural beauty.
Why Does Tanzanite Chip or Crack?
Tanzanite is a beautiful blue-violet variety of the mineral zoisite. Although it is suitable for several types of jewelry, it is more vulnerable to damage from hard impacts than gemstones such as sapphire and diamond.
To understand why tanzanite can chip, you need to know the difference between three important gemstone properties: hardness, toughness, and cleavage.
Tanzanite Hardness: 6 to 7 on the Mohs Scale
Tanzanite Toughness: Resistance to Breaking
Tanzanite Cleavage: Why a Strong Blow Can Cause Damage
The Mohs hardness scale measures a mineral's resistance to scratching. Introduced by German mineralogist Friedrich Mohs in 1812, the scale ranks reference minerals from 1 to 10 according to their relative scratch resistance.
Tanzanite has a hardness of approximately 6 to 7 on the Mohs scale. This means it is harder than some gemstones but can be scratched by sufficiently harder materials.
For comparison:

Important: A higher Mohs hardness rating does not mean a gemstone is unbreakable. The scale measures scratch resistance, not the amount of force required to chip or fracture a stone.
While hardness describes resistance to scratching, toughness describes a gemstone's resistance to breaking, cracking, or chipping when force is applied.
According to the Gemological Institute of America (GIA), tanzanite has fair-to-poor toughness. This makes it more susceptible to damage from sharp impacts than certain tougher jewelry gemstones.
For example, accidentally striking a tanzanite ring against a hard countertop could damage an exposed edge. The possibility of damage depends on the strength and direction of the impact, existing fractures, and how the gemstone is secured.
Cleavage is a mineral's tendency to split along specific structural planes within its crystal.
Tanzanite has perfect cleavage in one direction. This means that an impact applied in an unfavorable direction may cause the gemstone to split or fracture along a cleavage plane.
Not every accidental knock will damage tanzanite. However, its cleavage makes avoiding strong impacts particularly important.
Key takeaway: Tanzanite can chip not simply because of its Mohs hardness, but because its toughness and cleavage influence how it responds to impact. Understanding all three properties gives you a much clearer picture of its durability.
What Can Cause Tanzanite to Chip or Break?
Tanzanite damage often occurs through accidental contact with hard surfaces or activities that put pressure on the gemstone.
Common situations that can increase the risk of chipping include:
- Hitting hard surfaces: Accidentally striking a ring against countertops, door handles, metal objects, or furniture.
- Dropping jewelry: A fall onto tile, concrete, or another hard surface may cause a chip, crack, or setting damage.
- Exposed gemstone edges: Sharp corners and unprotected girdle areas can be more vulnerable to direct impacts.
- Heavy physical activities: Weightlifting, gardening, manual work, and sports can expose rings to repeated knocks or pressure.
- Existing fractures: A gemstone with an existing fracture may be more vulnerable to further damage.
- Loose or damaged settings: Worn prongs or poorly fitting settings may allow movement or reduce the protection provided to the gemstone.
- Sudden temperature changes: Significant thermal shock can damage tanzanite and should be avoided.
It is important to distinguish between normal wear and actual damage. Minor surface abrasion may gradually affect a gemstone's polish, while a sharp impact can cause a more noticeable chip or fracture.
Does Tanzanite Scratch Easily?
Tanzanite is moderately resistant to scratching, but it is not as scratch-resistant as sapphire or diamond.
With a Mohs hardness of 6–7, tanzanite may develop scratches or surface abrasion when it comes into contact with harder materials. The likelihood depends on the materials involved and how the jewelry is worn or stored.
What Is the Difference Between a Scratch, Chip, and Crack?

Not all visible lines inside a tanzanite are scratches or cracks. Some may be natural internal features. If you are uncertain, a qualified gemologist can help identify the issue.
Which Gemstone Setting Protects Tanzanite Best?
One of the most practical ways to reduce the risk of tanzanite chipping is to choose a well-designed jewelry setting.
A gemstone setting is the metal structure that holds the stone in place. Some designs provide more protection to exposed edges, while others prioritize visibility and light exposure.
Although no setting can make tanzanite completely resistant to damage, a protective design can make a meaningful difference.
Bezel Setting: A Strong Protective Choice
- Offers substantial protection around the gemstone's edges.
- Can reduce snagging compared with some elevated prong settings.
- Works well in many low-profile and contemporary ring designs.
- Can be a practical option for people who want additional protection for a tanzanite ring.
Prong Setting: Beautiful but Requires Care
Halo Setting: Additional Protection Depends on the Design
Channel Setting: Useful for Selected Tanzanite Designs
A bezel setting surrounds the gemstone's edge with a metal rim. A well-constructed full bezel can help protect the girdle and reduce the risk of the gemstone catching on clothing or receiving direct impacts around its perimeter.
Advantages:
Consideration: A bezel does not prevent every kind of damage. The gemstone's exposed upper surface can still be struck, and the setting must be properly constructed.
Prong settings use small metal claws to secure the gemstone. They are popular for solitaire and engagement ring designs because they allow much of the gemstone to remain visible.
However, exposed edges and corners may be vulnerable to accidental contact, particularly in high-profile settings.
For tanzanite, consider a secure, thoughtfully positioned prong design with appropriate protection for vulnerable areas.
Regularly inspect the prongs for signs of bending, wear, or looseness. If the gemstone moves or rattles, stop wearing the ring until a qualified jeweler checks it.
A halo setting surrounds the center gemstone with smaller accent stones or decorative metalwork.
Depending on the construction, the surrounding halo may provide some protection against impacts from certain directions.
However, not every halo setting protects the center stone equally. A raised tanzanite may still have exposed edges or surfaces.
Choose the setting based on its actual construction rather than assuming that the presence of a halo makes the gemstone safe from chipping.
A channel setting holds gemstones between two parallel metal walls. This design is commonly used for rows of smaller accent gemstones or multi-stone bands.
The metal walls can help protect the sides of the stones, but a channel setting is not automatically the best solution for every tanzanite shape or large center gemstone.
The quality of construction, gemstone fit, stone size, and exposure of the upper surfaces all influence protection.
Which Setting Should You Choose?

Our recommendation: If protecting the gemstone is your priority, begin by considering a properly designed bezel or another secure, low-profile setting. Always evaluate the actual jewelry design and your wearing habits rather than relying solely on the setting's name.
Is 14K White Gold or Platinum Better for Protecting Tanzanite?
Both 14K white gold and platinum can be suitable metals for tanzanite jewelry. However, the security of a gemstone depends primarily on the setting's construction, craftsmanship, condition, and proper fit rather than the color or name of the metal alone.
14K White Gold for Tanzanite Rings
14K white gold is a popular jewelry metal because it combines the beauty of gold with alloying metals that influence its strength, color, and wear properties.
Its bright white appearance complements the blue-violet hues of tanzanite, making it an attractive option for elegant rings and other jewelry.
White gold is often rhodium-plated to create a brighter finish. This plating can wear over time and may require maintenance.
Some white gold alloys contain nickel, which can cause allergic reactions in sensitive individuals. If you have known metal sensitivities, ask about the specific alloy before purchasing.
Platinum for Tanzanite Rings
Platinum is another established choice for gemstone jewelry. Its naturally white appearance, density, and suitability for fine jewelry settings make it an attractive option.
Platinum is often more expensive than 14K white gold, and its surface can develop a patina with wear.
However, it is incorrect to assume that platinum automatically provides less security than white gold. A properly designed platinum setting can also hold and protect tanzanite effectively.
Final verdict: Choose between white gold and platinum based on your budget, preferred appearance, maintenance expectations, metal sensitivity, and the quality of the complete setting. Neither metal eliminates the risk of tanzanite chipping.
How to Prevent Tanzanite from Chipping
Although tanzanite cannot be made completely damage-proof, simple precautions can help reduce the risk of scratches, chips, and cracks.
Remove Tanzanite Rings During Physical Activities
Avoid Wearing Tanzanite While Doing Household Chores
Store Tanzanite Jewelry Separately
Avoid Sudden Temperature Changes
Inspect Your Tanzanite Jewelry Regularly
Choose Jewelry That Matches Your Lifestyle
Remove your tanzanite ring before gardening, exercising, lifting heavy objects, playing sports, or performing activities that could cause the gemstone to strike a hard surface.
These precautions are especially important for rings because hands frequently come into contact with everyday objects.
Take off your jewelry before cleaning, handling heavy cookware, moving furniture, or working with potentially damaging chemicals.
Even ordinary activities can create accidental impacts or expose gemstones and their settings to unnecessary stress.
Keep tanzanite in a soft jewelry pouch or a separate compartment of a lined jewelry box.
Avoid storing it loose alongside harder gemstones such as diamond and sapphire, which may scratch its surface through contact.
Tanzanite is generally stable under normal wearing conditions, but very high temperatures and abrupt temperature changes can cause damage.
Do not expose tanzanite jewelry to steam cleaning, intense direct heat, or rapid changes between extreme temperatures.
Check whether the gemstone remains securely positioned and whether any prongs, bezels, or other setting components appear damaged or loose.
If you notice movement, a new chip, or an unusual line that could indicate a fracture, stop wearing the jewelry until it has been professionally examined.
If you frequently work with your hands, tanzanite earrings or pendants may be more practical than a ring exposed to repeated impacts.
If you prefer wearing a tanzanite ring regularly, choose an appropriately protective setting and remove the ring when your activities create a higher risk of damage.
Can a Chipped Tanzanite Be Repaired?
Yes, some chipped tanzanite gemstones can be repaired, but the available options depend on the size, location, and severity of the damage. A small surface chip may sometimes be removed through professional polishing, while more extensive damage may require recutting or gemstone replacement.
Because tanzanite has cleavage and is sensitive to certain impacts, repair work should be handled by an experienced professional.
What Should You Do if Your Tanzanite Has Chipped?
- Stop wearing the jewelry: Continuing to wear a damaged gemstone may increase the risk of further damage or loss.
- Keep any loose fragments: If a piece has broken away, preserve it in a small, secure container for professional assessment.
- Avoid DIY repairs: Do not apply household glue, polish the damaged area yourself, or expose the stone to heat.
- Consult a qualified jeweler or gem cutter: A professional can inspect the gemstone, setting, and location of the damage.
- Discuss realistic repair options: Depending on the situation, these may include repolishing, recutting, resetting, or replacement.
Can a Small Chip Be Polished Out?
Sometimes. If the chip is shallow and located in an area that can be safely worked, a professional gemstone cutter may be able to remove it by repolishing or making a minor adjustment to the gemstone's facets.
However, polishing removes material and may affect the gemstone's appearance or weight. The repair should be assessed carefully before any work begins.
Can a Cracked Tanzanite Be Recut?
In selected cases, recutting may remove damaged material and produce a smaller usable gemstone.
This process can significantly reduce carat weight or alter the stone's original shape and proportions. Deep fractures, unfavorable cleavage, or extensive damage may make recutting impractical.
Important: A crack extending through a gemstone cannot necessarily be made structurally sound by polishing or hiding it beneath a setting. Professional assessment is essential.
Is It Better to Repair or Replace a Chipped Tanzanite?
The decision depends on several factors:
- The location and extent of the damage.
- The gemstone's quality, carat weight, and approximate replacement value.
- Potential weight loss from repolishing or recutting.
- The cost and feasibility of professional repair.
- The sentimental importance of the original gemstone.
For a gemstone with significant sentimental value, a professional evaluation may be worthwhile even if the repair is complicated. In other circumstances, replacing the damaged stone may be more practical.
How to Clean Tanzanite Jewelry Safely
Proper cleaning helps maintain the beauty of tanzanite jewelry without exposing it to unnecessary damage.
According to GIA, warm, soapy water is the recommended safe cleaning method for tanzanite. Ultrasonic and steam cleaners should not be used.
Step-by-Step Tanzanite Cleaning Guide
- Inspect the jewelry first: If the gemstone is loose, cracked, chipped, or visibly damaged, avoid cleaning it yourself until a professional has examined it.
- Prepare mild soapy water: Mix a small amount of mild soap with lukewarm water.
- Clean gently: Use a soft, clean cloth or a very soft brush without applying pressure to the gemstone or setting.
- Remove residue carefully: Use clean lukewarm water to remove soap, taking precautions against dropping the jewelry or losing it down a drain.
- Dry with a soft cloth: Pat the jewelry dry using a clean, lint-free cloth and allow remaining moisture to dry naturally.
What Should You Avoid When Cleaning Tanzanite?
- Ultrasonic jewelry cleaners.
- Steam cleaning machines.
- Abrasive cleaning powders or harsh scrubbing.
- Strong acids or chemical cleaning solutions.
- Very hot water and sudden temperature changes.
- Home polishing or scratch-removal methods.
If the gemstone has a special coating, fracture filling, or another treatment, ask a qualified jeweler about any additional care requirements.
Can You Wear Tanzanite Rings Every Day?
Tanzanite rings can be worn regularly, but they are not as forgiving of rough wear as jewelry featuring tougher gemstones.
The suitability of a tanzanite ring for everyday use depends on your activities, the gemstone's condition, and the design of its setting.
If your routine includes frequent physical work, sports, or repeated contact with hard surfaces, an occasional-wear tanzanite ring may be a more practical choice.
On the other hand, if you work in a relatively low-impact environment and remove your jewelry during risky activities, you may be able to enjoy a well-designed tanzanite ring more frequently.
