Is My Ring a Genuine Alexandrite Ring?

by Michelle
(Springfield, MA)

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

large alexandrite ring
by: Anonymous

I inherited an Alexandrite stone which my mother had placed in a ring and gave to me. The stone is about 3 karats. It does have a small chip. The story I have always been told is that my step grandfather purchased a bag of stones.....which my mother inherited..........from the boat people in the Philippines. He was Navy. This was a very long time ago when he acquired the stones. Mine is a deep purple color and changes in the light. sometimes to shade of green and pink. I have taken it to jewelers before and received mixed opinions as to whether it is real or not. Sometimes the jeweler will look at the stone and with trembling lower jaw, ask me if I know what I have. I say yes, an Alexandrite. Is it possible it is real since it was purchase so long ago. Probably in the 40's or 50's


You need to take the gemstone to a certified gemologist who can analyze the stone thoroughly. Honestly though, I doubt it is real alexandrite. An alexandrite gemstone of the size - even from the 40s and 50s - would have been valued in the tens of thousands of dollars. Remember, we are talking about one of the rarest and most valuable gemstones in the world. And because synthetic alexandrite was produced well before this time, it is very possible that you have a synthetic alexandrite gemstone. Again, the only way to know for sure is to have the stone analyzed by a professional gemologist. I suggest checking the American Gem Society for a certified gemologist near you.

alexandrite real or fake
by: melissa

Does real alexandrite glow under the black lite and is synthetic stone worth anything?


Hi Melissa,

Real alexandrite does not unfortunately glow under black lights, it would make things much easier if it did! The only way to truly identify alexandrite is to have it analyzed by a certified gemologist, and in some cases a laboratory is needed to confirm the findings. Synthetic alexandrite is not worth much - unfortunately the synthetic varieties are not valuable at all.

Real Alexandrite
by: Anonymous

I have my grandpa's sailor rings from the 1940's. The stone is almost 4 carats of real Alexander, how much do you think its worth?



Because synthetic Alexandrite was available before this time, and because this is such a rare gem (4 carats would be extraordinarily rare even for that time), it is best to have the ring evaluated by a certified gemologist so you can assess if the stone actually is real and if it is what its value would be worth.

Best of Luck!

Some easy ways to tell.
by: Kim Shaffer, G.G.

I am a G.I.A. trained Graduate Gemologist. I just happened upon this page while researching what people do with inherited colored gemstones.

There are some simple things a person can look at that will tell you positively that a gemstone is not an Alexandrite. Ninety-nine times out of a hundred (if not more) this will answer the question.

The vast majority of what people own that they think is Alexandrite is synthetic Alexandrite-like Sapphire. This is an inexpensive man-made stone.

If your stone changes from any color of purple to any color of blue, it is a synthetic Alexandrite-like Sapphire.

An Alexandrite, whether it is natural or synthetic (really Alexandrite, but man-made) will change from some color of red to some color of green. If you have a stone that does that, then you need to consult a gemologist.

I hope this information is of some help.

my ring
by: Anonymous

it was my moms, her birthstone Alexandrite. It goes from a bluish-green in sun light and in artificial light, it changes to purple. Been trying to find a place to see if it is man-made or real and get it appraised. it looks to be like a 1/4 carat gem stone. the ring itself maybe a 10k gold ring.. So if anyone knows a reputable person in or around the S.E. Oklahoma area, let me know. I cannot seem to find one. Thanks for all or any help!


Hello - Suzanne Gardner from Everything Wedding Rings, I edited out your email address so it wouldn't be published live. So, if anyone can recommend someone - do feel free to post it here! Also, I would recommend checking out the American Gem Society website to locate a certified gemologist in your area.

My ring
by: Lara

I was given a alexandrite in 1962, my mom bought it for me thinking it was an amethyst. It goes to a rich purple in indoor lighting and then outdoors a blue green. I remember once under a strange sky it became a beautiful shade of green. But as I read more I think it is probably man made.

My find in a button box
by: Bobbie

While digging through an inherited button box I found a pair of earrings, silver metal later to be noted as silver and marked Jerusalem on the back. There were these strange stones in the earrings that would change color under different settings, deep pink or blue and I just knew I had found a treasure. But, once I took them to a jeweler in Los Angeles to have them set in a more modern pair of earrings I was assured that they were indeed lab created. My friend who owned these had made a world tour as war was breaking out in 1937-1938 and traveled to Jerusalem. The jeweler said many jewels made it to other countries at that time and lab created stones were made at that time as well.
So, no treasure except in sentimental memories. I love them and wear them often.

Possible alexanderite
by: Sarah

I have a ring I think was from late 1800s to early 1900 from my 3rd or 4th time grandmother. I was told by one jewelry store that it was an alexanderite and needed to get it certified after I got new prongs on it. I'm not sure how big it is I think a carrot. It sometimes looks like a light mauve green sometimes gray greeneish. then a very light mauve sometimes kind of yellowish mauve.
