Hi,
I have been collecting ceystals in their raw form for a while and have lots of experience with identifying raw crystals but none with cut gems.

I recently ordered one pendant listed as Chrome Diopside from India and when it arrived it looked to me like glass, because I could not see any imperfections. Then I looked up cut Chrome Diopside on gem websites and it looks closely like mine.

I am wondering if you wiuld be able to tell from he photo whether it is real or glass / synthetic etc?

Thank you!

(Not sure if I am attaching the right way and if the photo went through, I hope it did)

Doesn't look like any Chrome Diopside to me. Hard to tell from your image, image is somewhat out of focus(blurry).
Maybe try to place some white light from behind and a better image, not to much light as to make it hard to see through stone.

Looks like glass to me. But not reliable from just a picture. An instant ID in a lab.

I think I know exactly the type of listing. I've seen a lot of them on eBay with improbable gem IDs thrown onto them.
The quick test for glass is to touch it to your lip--glass has lower thermal conductivity than a crystalline gem so it will feel warmer to the touch. Have a known glass and a known-not-glass stone to compare it to.

Imperfections (normally we call them inclusions) may or may not show depending on the type of stone and even then you would need to be trained to know what you're looking for. As others have said before, pictures aren't a good way to identify them and unfortunately the one you have doesn't have the right lighting or is too blurry for anyone to really get a clear image. I'm in agreement with others that it sort of has a couple of the telltale glass signs but you would need better pictures for us to even have a chance at guessing.

The main things you'll find in glass are rounded facet edges or bubbles (usually either round, doughnut shaped or elongated). There are a few other things as well but those would be the first things I'd be looking for. If you can get an image with light coming from the back of the stone (transmitted light) and a few different angles with both reflected, meaning top lit, and transmitted light then we might have a better chance at guessing.

Looking at the metal it's set in though even that isn't the best of quality and I would be making sure it's an actual precious metal (ie. silver) as that could be another indicator whether they would use a real stone or just glass/paste.

If you have more specific questions then we can certainly try to help but in general, we will probably end up suggesting bring it to a local jeweller or appraiser and have them tell you as they would be able to actually test and see the stone where pictures are never an accurate way of being able to tell what a stone is.

Thank you so much for all your replies.
I don’t have an access to a lab but may see if a local jewelry store may be willing / equipped to figure it out. I am including two more images, just in case they may give you more details to be able to tell:

Since it was a yes or no question you asked, my answer is no, not chrome diopside.

The two new pictures clearly show a large round gas bubble. Therefore without doubt, the correct identification is glass.

Agree as well. It appears to be fairly large oval and eye visibley clean, that alone would most likely eliminate it as CD. Thicker CD can be somewhat black in appearance.

Greatly appreciate your responses, thank you so much!
It confirmed my feeling about it, which was the reason I asked the question.
The picture included on the sale page was taken from a different angle and darker-looking and many of the other items that the seller was selling were real and uncut stones which I was familiar with, so that influenced my decision to get it from him. I will stay away from getting cut gems till I learn more.
Thanks again!
