Possible Alexandrite?

Pardon me if I am in the wrong place but I stumbled across your page while researching online. I have really enjoyed reading the posts!

Hello, Lizc

Hello… thank you for your reply. I hope you are doing well today!

Is it possible to get it tested? do you have a gem testing lab nearby?

It is unlikely to be an alexandrite. It maybe a color change garnet or color change sapphire

Hello…I want to get it tested. Currently looking for where to go in the Chicago area. Hopefully I will be able to update you soon!

Thanks Lizc for the trust placed on our forums. The thread on Alexandrites started on May 21st 2014 by Gemlite generated an extensive discussion, citing alexandrites of different countries of origin that appeared at public auctions conducted by Christie’s and Sotheby’s over the years, and went on till around the end of August 2014. The discussion brought out the salient features of Alexandrites from source countries such as Russia, Sri Lanka and Brazil and also established a market ranking for alexandrites based on country-of-origin, which goes as :- Russia - Brazil - Sri Lanka - Others. According to this discussion the average price-per-carat value of Russian alexandrites vary between US$50,000-US$70,000. The PPC values of Brazilian alexandrites vary between US$20,000-US$50,000 and those of Sri Lanka alexandrites between US$5,000-US$20,000.

As a follow-up to my observations above, I personally feel that the gemstone set in your ring is actually an alexandrite of either Brazilian or Sri Lankan origin. The cut employed on the stone is a modified round brilliant-cut. Alexandrites are usually cut as cushion, oval or round shaped stones. The above conclusions are based on information already known to us on the characteristics of color-change gemstones. However, the exact situation will only be revealed after scientific testing by a renowned gem testing laboratory. I am not sure whether such a gem-testing facility is found in Chicago. One of the renowned gem testing laboratories in the United States is the American Gemological Laboratories (AGL) situated in the heart of New York’s gem and jewelry district, providing detailed identification and enhancement reports, country-of-origin reports as well as complete colored stone analysis documents. Their offices are situated at 580, 5th Avenue Suite 706 - New York, NY 10036. Phone - 212 . 704 . 0727. You can contact them and find out whether they have a branch office in Chicago, Illinois or any other city nearby. Their working hours are from 9.00 am to 5.00 pm Monday through Friday.

Thank you SO much for your detailed information and for making it so simple to understand! I have been overwhelmed with all the information online but you have simplified it. Thank you!
