Is There Fake Tanzanite?
Tanzanite is a rare and precious gemstone that has been making headlines in the jewelry world for its stunning beauty and rarity. With its vibrant blue-violet color, it’s no wonder that tanzanite is in high demand. But with great demand comes great supply, and unfortunately, fake tanzanites have started popping up on the market.
The Origins of Tanzanite
Tanzanite is a gemstone that is found exclusively in Tanzania, East Africa. It is a type of zoisite, a mineral that is also found in other parts of the world. However, the unique conditions in Tanzania, specifically the presence of metamorphic rocks, allow tanzanite to form in a way that makes it truly one-of-a-kind.
How to Spot a Fake Tanzanite
So, how do you spot a fake tanzanite? Here are some key characteristics to look out for:
• Color: Real tanzanites have a distinct blue-violet color. If it looks more purple or has a strange tint, it may be fake.
• Luster: Tanzanites have a high luster, which is measured on a scale from 0 to 7. A fake tanzanite will likely have a lower luster rating.
• Hardness: Tanzanites have a hardness rating of 6-7, which is relatively soft for a gemstone. Fake tanzanites may be made from harder materials like quartz or spinel.
• Clarity: Real tanzanites have few inclusions and in most cases are treated to enhance their color and clarity. Fake tanzanites may have visible inclusions or poor clarity.
• Weight: Tanzanites are relatively lightweight, especially compared to other gemstones of similar size. If it feels unusually heavy, it may be fake.
• Price: Fake tanzanites are often sold at a much lower price than real tanzanites. Be wary of deals that seem too good to be true.
• Certificate of authenticity: If the tanzanite doesn’t come with a certificate of authenticity from a reputable lab, it may be fake.
The Different Types of Fake Tanzanites
Fake tanzanites can be created in various ways, including:
• Lab-created: This type of fake tanzanite is grown in a lab using high-temperature and high-pressure conditions. They may have a similar chemical composition to real tanzanites, but their optical and physical properties will be different.
• Treated: This type of fake tanzanite has been treated with chemicals or heat to enhance its color or clarity.
• Simulants: Simulants are fake gemstones that mimic the appearance of tanzanite, but are not actually tanzanite.
