inclusions

[Bobby]

hi,id like help in identifying this inclusion.i do not know what gemstone this is.its a greenish yellow gem.

inclusion

under uv light

[Bobby]

i dont know why the same stone in uv in a dark room is more reddish .

First instinct is Scapolite. But on-line guesses are just that. Not reliable.

[Bobby]

Thank you for your reply.The specific gravity is around 3.5.

re: green stone
Does anyone else see what appear to be bubbles throughout this stone?

[Bobby]

just posting a few more pics of the stone.There are no round bubbles as such but i guess bubbles are elongated too.

[Bobby]

hi barbara yes i did notice the bubbles when looking at the pictures clearly.Looked into the stone again.I think it was just the way the picture was taken.Two pictures of the same inclusions .

Some of the inclusions look like Apatite XLS to me. Which again is consistent with Scapolite as the stone. Also the extent of scratches on the facets and abrasions at the facet junctions are consistent with a stone of low hardness. Finally, the iridescent inclusions/areas in the stone is common and indicative of Scapolite.

So hard to do this from pictures. Just a couple of minutes with the stane and all would be known with certainty.

hi,thank you for your reply .Those are not surface scratches but inclusions.Its actually a very old stone.Im just trying to figure out if its worth getting it tested.Atleast i now know its a natural.The inclusions are so unusual that i was confused .Icould test only the specific gravity which is 3.5.The weight of the stone is around 14.6 carats.

I have to disagree. In addition to interior inclusions of different types, the images you posted clearly show both surface abrasions, and abraded facet junctions. This I am very confident in.

I concur that both the types of inclusions, and the variety of inclusions shown in the images support a likely natural stone call. If you are accurate in your specific gravity calculation the stone is not Scapolite. Chrysoberyl and Topaz then become my most likely candidates. Both can have the yellow color and both can show red/orange fluorescence under UV light.

However, I still tend to lean towards Scapolite based on color, fluorescence, hardness, and inclusions.

How did you measure the specific gravity?

What is the resolution of the scale you used?

[Bobby]

The edges are chipped but let me check the surface and take a pic.Thank you

[Bobby]

some pics of the surface .

[Bobby]

these are some scapolites which i got cut myself ,rough is from south india.few other stones mixed.
