Tanzanite: Unique Zoisite Colors by GIA. What color is tanzanite? Typically, tanzanite, the December birthstone, is found in brown, blue, and violet colors. However, in recent years, a transparent, gem-quality green zoisite has been discovered in the Merelani Hills of mineral-rich Tanzania. The gemological properties are identical to those known for blue-violet or green tanzanite. In this video, Menahem Sevdermish discusses the many different tanzanite colors and hues and provides beautiful examples of both blue and green tanzanite gemstones. Also discussed is tanzanite’s most prized color, zoisite, which is a pure blue and similar to fine sapphire. Tanzanite is a pleochroic gem, which means it can show different colors when viewed in different crystal directions. This makes cutting a crucial element in determining the color the consumer sees when the stone is cut and set in jewelry. Understand the different quality factors that determine a tanzanite’s value, with color and cut leading the way.

i have a nice golden ring with tanzanite , i really love tanzanite.
Me too! My birthday is in December & Tanzanite has been designated another December birthstone. Definitely my favorite of all!
Hello. What is the meaning of the ‘natural heated’ tanzanite?
Is this considered to be treated or non treated?
Thank you
У меня тоже есть не гретый фиолетово- синий танзанит , 12 ct. Я его очень люблю. Он всегда разный , он живой .
Dep qua dung la da tu nhien cong ty GIA la nhat roi.
Đá này ở VN có hàng, đa số hàng đã qua nhiệt (màu xanh ánh tím violet). Cũng có 1 số viên chưa qua nhiệt mà xanh lá nhạt.
I own a dark blue tanzie of about 5 karats in weight. It is one of my favorite rocks I own.
Where I can get this real stone?? From Pakistan

Five carats.
I own just a ring of 1 karats,adore it.✨
thank for information
Great.
i have the green and the bicolor as well as the dark blue one i have a heart so cute i love tanzanite have been collecting since 2008 would love to sell some..any buyers i wonder
Very interesting
.
does heat treatment decrease the value of the stones?
(I still love the shades of colour though)
This has always been true. These stones are not new. To traditionalists Blue is better. To those that only want natural maybe this company with GIA may start a trend. Back in the 80s you could not give away fancy zoisite.
@@mylesharvey6488 oh right thanks
Nice steon 🇮🇳

You keep the fancy colors for your personal collection , lol since they are so rare hahaha
Indeed I had to contain my laughter. They rarely see the retail market is a More truthful statement.
the brown ones are not special in fact most tanzanites brown.
Where is this shop ?
Whow😍🤩
they will, of course, tell you that all colors of tanzanite are amazing because they are going to sell it to you for big $$$. lol!
Overrated, not as rare
Hi

this guy is trying to market junk lol
They are giving bad quality tanzanites fancy names so that they can sell it at a high price. Lol!
Very deep dark blue also come in unheated stones ,in fact the deeper they go the more naturally colored tanzanite they find that does not need to be heated , the so called fancy tazanite are not in the same league as the deep blue saturated stones , its not even close ,in fact they suck
