@Desertdi   Here's mine.  It must be 25+ct.  It's too big to wear but the silver work is exquisite. It changes from teal to deep wine.  I got it from a dealer in Bangkok from whom I bought a lot of jewelry.   The stone is so big, it doesn't photograph well.  Needs good light. 

@Kachina624    That IS exquisite craftsmanship!   I think I would wear it...  di

@Desertdi    Never heard if a color changing Tanzanite.  Must be a synthetic stone.

I have a very large ring that's a synthetic Alexanderite that is similar.

Tanzanite that was first mined is purple/blue/redish.  I purchased a Tanzanite 1.80 ring in Aruba ages ago for $1600, it now has an appraised value of over $8k

Take it to a jeweler would be my advise. I would say based on how long ago you bought it and where you bought it I'm guessing alexandrite. I know it's quite large, but many years ago while at a restaurant bar, the bartender had a ring on that was several colors every time you looked at it (this is before i ever heard of alexandrite) she said it was her husband's grandmother's ring, that was originally in a basket setting that she had reset. It was about 5 carets, and said it was an alexandrite. The ring today would probably be worth a fortune, it went from a brown color, to green, to blue, even red in certain light. That's why I would get it looked at

New veins in the mine have happened upon these beautiful colors.  I don't know why not much was ever known about the other colors of the mineral zoisite, but they exist @FatCatinCT .  They are not always mined in that color.  Fact is, Tanzanite is heat treated in many cases to get the colors that are sought after.

                            Your Alexandrite ring is beautiful.

              I have a synthetic Alexandrite pendant that I got from

           an Egyptian jeweler.  It is pear shape and it changes from

           a reddish purple to dusty or grayish teal.

1st one I'd say is Tanzanite.

I have a very similar stone that I bought 50 years ago from Bangkok. Mine is a synthetic Alexanderite, currently valued at over $1000.

I have a fairly old Technibond line bracelet with lab Alex stones. It has eighteen 7mm round cut stones set in Technibond gold plate. Color change is 100%. No idea how much the stones are worth. Back in its day Technibond had many kinds of lab stones in their collections.

Really large Alexandrite does not exist.  It doesn't occur in nature very large.  So, if you have one that is humongous, it pays to check and make sure that it is not a synthetic (unless of course, you already know it is synthetic).

Alexandrite does not [did not] occur naturally in large stones.
