What is the form of Opal?

Opal has no definitive form. The word used to describe opal is "amorphous" which means: lacking definite form - having no specific shape.


What is the weight of 10 carots total weight marquise cut loose opal lot Each opal measures approximately 4x2mm?

The is one factor missing .... how many stones make up the 10 carat total ? without this , the question is nonsensical. Rod Keady Actually, carat is a measure of weight already. It is the same as 200 milligrams. So 10 carats would be 2 grams. That is not a lot. Opal has a specific gravity around 2, so that means it has twice the density of water. Two grams of water is about 2 cubic cm, so 2 grams of opal would be about 1 cubic cm volume. Since some opal has a specific gravity of up to 2.25 or so, the volume of opal could be as little as 0.88 cc. That means, however, that you have quite a few of these small opals. Probably as many as 20 or 30 -- maybe more. Since they were cut, you really only have a small slice of opal in each cut, topped by a cabochon of crystal quartz. The specific gravity of quartz is higher than that of opal, which probably reduces how many stones you have, but still, you should have quite nice number of them. 4mm x 2mm is the perfect size to set in a ring or in earrings.

What is the identity of the gemstone Opal Diamond Garnet Topaz?

To learn the identity of the gemstones opal, diamond, garnet, and topaz you need to look at their color, transparency, specific gravity. You need to light the stone's surface and look through a loupe. You also need to determine the birefringence and refractive index.
