Blue Garnets???

[innerkitten]

I was enquiring about a very pretty antique ring on Ebay that the poster said had blue garnets. From what I understand they come in every color of the rainbow except blue. Does the seller know something I don''t know?

No... but he would like you to believe it

It's sad there are so few blue gems, but blue garnets are not an option. Except syntetics - those come in blue too.

Color change garnets have the reputation to get quite blue-ish green, a cold green really. And this is the blue-est I know garnets can be.

i have some color-change garnets that turn a sort of steel blue in the right light, but as far as i know, that's the only kind of blue garnets you're going to see.

Several years ago a major gem dealer I know was importing color change garnets from the Bekily area of Madagascar. One of the color positions was a definite blue with a very slight greenish cast. He discovered that some of them were not color-changers but remained blue in all lights. He showed me a couple of parcels and they were primarily blue in both daylight and incandescent.

He was wholesaling them at $800 a carat so I doubt any would be showing up in Ebay jewelry items. At the time I wondered if they would qualify as pure blue but figured the GIA would sort it out. So far I've not seen anything further about them in G & G.

I have a parcel of Tanzanian color change garnets and many of them show a pale steely blue as one color position alternating with a rosy pink.

As the others have said, the only blue garnets that I have had the opportunity to see have been the color change variety. Here is a pic of the blueist one I have ever seen. In very "high temp, K" lighting it becomes a steel blue like spinel. Hope you like the picture

When the color change garnet variety from Sri Lanka was discovered about 7 years ago, it ended the rule about blue garnets. I own many that are very blue in sunlight, some more teal, some more steel blue. The color change stones from Madagascar are similar but don't seem to have as big of a change. The Tanzanian are not even close, the reds are more brownish and the greens are more muddy without much blue. Some of what is floating around the TV and EBAY type market is color enhanced that is not stable. I hope to find out next week in Bangkok what is the cause of the teatment as the regular color change material is not treated. For those who like colorchange stones, the supply is pretty much gone. I suspect good ones totally gone in one more year. Not offering investment advise, just have been a big buyer of this material for the last 7 years. Can't seem to find much of it for the last year. I have a 3.5 ct that is not for sale but I will try to post pictures (not my strenght) so you can see the light change. It is the best one I have ever seen.
