Hello,got this ring .its without certification.changes color.Any opinions please ,is it worth getting it certified.
Just as a matter of practicality, this is a nice color change and a very large stone for alex, so I am assuming, until proved otherwise, that this is synthetic. Alex in that size would never be seen commercially. Could be any kind of synthetic, various species are made with color change. Also there is chpiing at facet junctions…not impossible in chrysoberyl, but more unlikely, given that the ring doesn’t look worn, so probably wasn’t worn a whole lot. inclusions look like bubbles except for the one that looks like an insect on the lower right…which could be a chain of bubbles (???). So is it worth it to send this out for a $300 ID when it might come back as a $50 synthetic stone? You know that adage, if it seems too good to be true… -royjohn
Thank you for your reply. I’m taking it to a gemologist today . Fingers crossed . I do have another Alex of 12.5 carats and a few smaller ones with good color change but this is totally different. The color change is purple to red which is not standard Alex.
HI its resembles a synthetic Maybe corundum colour change (sapphire) diagnostics from images photos is not my way but i see double refraction
The Alexandrite beautiful colour strengths almost Demantoid Green Garnet And hot Rasberry pink very nice

The first one I did check everything it gives refractive index hardness everything of alexandrite . So I guess it’s a synthetic alexandrite cause alexandrite definitely does not have this color change .
It’s diff in diff lights . One loves some colors and hates some… Alexandrite is definitely amazing.

Nice to see you have GIA Report would of been nice if it said origin brazil have had it valued yet?
I havnt had it valued . I’m in Dubai and have no idea how and where to do it . I’ve been thinking about sending it to gubelin for one more certificate and they do rate gemstones . I’d definitely like to insure it and maybe even sell it. I just don’t know where to start . Any suggestions I’d be grateful.
Unfortunately, the new GIA lab in Dubai only accepts diamond clients. There doesn’t seem to be any current expansion on those services in the near future. https://www.gia.edu/gia-news-press/expansion-with-state-of-the-art-laboratory-dubai
And it looks quite expensive, too! 
IGI has a lab there: Google Search
Cheers!
