Although there are several Genuine Gemstones know that change
color, I am only aware of Sapphire that changes the colors seen in
Synthetic Sapphire making it a Synthetic not an Imitation.
I did not use the word imitation, I used the word simulant. But a
synthetic color change corundum sold as a synthetic alexandrite,
would be an imitation. To me, a imitation or a simulant has some
characteristic in common with the original, but not exactly or
completely.
Please don’t get confused with what is done and FTC guidelines. If
you can supply someone with something they want at a price they can
afford that looks like something they want that they can’t afford,
they don’t necessarily care what it is called. I can tell them it is
a simulant, not a synthetic, ect. and I don’t think they could
repeat back to me what I said, but I did disclose.
I know a stone dealer that when you order synthetic alexandrite, you
get color change corundum, which does look somewhat like some natural
alexandrite I have seen, as natural material can vary quite a bit.
Light colored natural alexandrites look like the synthetic color
change corundum from the stone dealer I use. If I order synthetic
alexandrite, and receive color change corundum, I have been sold
something simulating alexandrite. Whether it is a good simulantor not
is up to the observer.
The customers who wanted synthetic alexandrite were happy with what
I showed them and bought them. I research a lot of different stone
dealers to get the best representation of natural stone colors in
synthetic or imitation material. Having been obsessed with gemstones
for 30 years, I have seen many of the finest gem quality stones,
aquamarine, tanzanite, color change tanzanite (oh if I could have
afforded one!!!), pariba tourmaline when it first came on the market
at $250 a carat, bi-color tourmaline. Over the last 30 years, I have
seen material that has come, and gone, probably never tobe seen
again.
If anyone wants a rarity, a friend of mine has transparent faceted
light yellow oligoclase for sale. So if you want some homework, read
up on feldspar and find out the difference between plagioclase,
orthoclase, and oligoclase.
