Is My Ring a Genuine Alexandrite Ring?

by Michelle

I have a ring that I bought under the belief that it is alexandrite, how would I be able to tell if it is in fact real or fake? It is a very light clear color but it changes from various shades of pale blue to clear to green to purple... the stone is over a carat.

It is set in a plated setting so I am confused as to the true certification of the gem... not that it matters that much I bought it for $25 dollars at a flea market... but I’m curious. Thank-you very much.


Hi Michelle,

I think what you may have purchased is a ring made with a synthetic lab created alexandrite stone – or it could even be made with colored cut glass.

The price is the first clue that the ring is not made with genuine alexandrite. True alexandrite commands high prices. Mediocre gems up to a carat are priced around $500 dollars, okay gems are around $1,500 to $2,000 dollars a carat, a ‘good’ alexandrite gem up to a carat is around $5,000 dollars and an alexandrite with excellent cut and clarity characteristics that displays the most desirable color change qualities can command up to $15,000 per carat.





The chances of finding a true alexandrite at a flea market for $25 dollars are pretty low - and sadly, probably less than the chances of winning a PowerBall lottery ticket! Plus, if the ring was actually made with genuine alexandrite, it should have come with a laboratory certificate from a reputable company – like the AGS or GIA.

Alexandrite is a type of color change chrysoberyl gemstone, but over 30% of the gemstone must change color in order to be classified as an alexandrite, plus the color change has to be of a specific shade and intensity.

The reason I mention the color change chrysoberyl is because recently a lot of color change chrysoberyl is being labeled and sold as ‘true alexandrite’ when it really isn’t alexandrite at all. But – even a color change chrysoberyl is priced at a few hundred dollars a carat, which is why I don’t think your ring contains a color change chrysoberyl gemstone either.

Synthetic lab created alexandrite is priced at around $20 to $30 dollars a cart when it is set in a ring – and so because of the price of the ring and the location you purchased it in, I’m pretty sure that is what you have. Or as I mentioned before, it could also be an eye catching piece of colored cut glass.

The only true way to know that a gem is genuine alexandrite is to have the gemstone examined and certified by a laboratory. With a large amount of synthetic alexandrite on the market – plus color change chrysoberyl being marketed as alexandrite – anyone who is interested in a wedding ring or engagement ring made with true genuine alexandrite must shop with a reputable jeweler and make sure the ring comes with a certificate from a reputable laboratory.

Hope this info helps!

Antique Ring - Set in Platinum - I think it is Alexandrite
by: Jan

40 years ago I purchased a 3 stone ring ( 1 carat each) at an estate sale. It was said to be genuine Alexandrite. I purchased it because I liked the ring. It normally has a purplish color but changes and picks up the color that is nearest to the ring. If its on green, it picks up a greenish color. Each stone has 6 platinum prongs that hold it in place. How can I determine if the stones are genuine Alexandrite?

Hi Jan - really the only way to determine if the ring is made with genuine Alexandrite is to have the ring analyzed by a qualified jeweler.

As for clues that can help you to determine if the stones could be genuine alexandrite - the price you paid for the ring could be a good place to start. Three one carat alexandrite stones - even 40 years ago - would be priced at thousands of dollars depending on the quality of the stones. So, if you paid a low price for the ring it probably is not made with genuine alexandrite.

The color change description sounds a little off to me too though - because alexandrite changes color based on lighting. Sunlight (or indoor fluorescent light) and incandescent light is what induces the color shift in alexandrite gemstones - not the color of surrounding objects. Real alexandrite is a green color under sunlight or fluorescent light and changes to a red/purple color under incandescent light. So, that would be a concern.

But again, the only real way to find out for sure is to have the ring analyzed. Good luck and I hope you find the answer you are looking for!

not real

none of those are real not to be a downer but they change from green to red blue to green some times purple but not clear maybe a little brown and they are super rare 1 caret is worth atleast a 1k if its poor quality anything over 1 caret poor quality is upwards to 10-20 k per caret really good quality meaning light change and clarity 1 caret 50-100k per caret the light change is from candle light to sun light type of thing it will be a different color in those to lights
