Introduction to Tanzanite
Tanzanite is a unique and highly sought-after gemstone that is found exclusively in Tanzania, Africa. Discovered in 1967, this blue-violet mineral has quickly become one of the most popular gemstones in the world. It is a variety of the mineral zoisite, and is a popular alternative to sapphire and blue topaz.
Characteristics of Tanzanite
Tanzanite has a unique color that ranges from deep blue to violet, and is often described as a "velvety" blue. It is a relatively hard stone, with a Mohs hardness of 6.5-7, which makes it suitable for use in jewelry. However, because tanzanite is a relatively new gemstone, it is not as well-known as other gemstones, and as a result, it is often considered a more fragile gemstone.
Grading and Quality of Tanzanite
The quality of tanzanite is determined by a number of factors, including color, clarity, and cut. The most highly prized tanzanite is a deep blue-violet color, with no visible inclusions and a well-cut stone. However, tanzanite is also found in other colors, including brown, yellow, and green, which are even more valuable these days.
Color is the most important factor when grading tanzanite, and the Gemological Institute of America (GIA) has developed a color grading system specifically for tanzanite. This system ranges from "D" (D'Block) to "A" (light Purplish).
Clarity is also an important factor when grading tanzanite. The GIA has developed a clarity grading system that ranges from "F" (flawless) to "I" (included). A "F" grade means that the stone has no visible inclusions, while an "I" grade means that the stone has visible inclusions.
Care and Cleaning of Tanzanite
Because tanzanite is a relatively fragile gemstone, it is important to take care when cleaning and wearing it. Here are some tips for taking care of your tanzanite jewelry:
Avoid exposing tanzanite to high heat, as this can cause the color to change or fade.
Avoid exposing tanzanite to chemicals, such as chlorine or bleach, as this can cause damage or discoloration.
Clean tanzanite with warm, soapy water and a soft brush. Avoid using ultrasonic cleaners or steam cleaners.
Store tanzanite in a cool, dry place, away from other gemstones that could scratch it.
Conclusion
Tanzanite is a unique and highly sought-after gemstone that is found exclusively in Tanzania, Africa. Its unique color and relative rarity make it a popular alternative to sapphire and blue topaz. However, because tanzanite is a relatively new gemstone, it is not as well-known as other gemstones, and as a result, it is often considered a more fragile gemstone. By understanding the characteristics, grading, and care of tanzanite, you can ensure that your tanzanite jewelry will be treasured for years to come.

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.
When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.
