What do emeralds look like when well cut???Why do the shine green???

Question

If it was dark or light green,what would this mean abot the emerald???...Thank you

Answer 1

Emerald is one variety of the mineral beryl (Be3Al2Si6O18). (It is not a beryllium crystal. Beryllium is just one of the elements that goes into the mineral.) The ideal mineral is colorless. The colors of the various gem varieties of beryl are the result of impurities, other elements substitute for the aluminum or silicon atoms. In the case of emerald, the green color is cause by small amounts of chromium and vanadium. (This is by definition. If a green color is cause by some other element, then it is not an emerald.)

As for what an emerald looks like when it is well cut, well that is rather hard to describe without pictures. However, when looking at the stone, you should look at corners. The ridges that come into a mutual corner should all come to the same point. The further off of this arrangement the ridges are the worse the cut. This is one thing that you can look for. There are others, but I would really need pictures to show you.

colored green by trace amounts of chromium and sometimes iron .. maybe the more Cr and Fe the deeper green .. adding to that Emeralds come in many shades of green and bluish green. There is a wide spectrum of clarity, along with various numbers of inclusions. Most emeralds are highly included, so it is quite rare to find an emerald with only minor inclusions. so the inclusions play a role in coloring the mineral ..

it depends upon the cut of the stone; an "emerald" cut is rectangular. other various cuts are, "princess", "brilliant", "radiant", "round", "square", etc. yes they shine green, it's a green stone. the shine can be very sparkly depending upon the cut and how high /deep the gallery of the stone is, and the setting. different settings allow more or less light to enter the stones cut facets. the quality of the stone depends upon where it's mined...braziliian emeralds are very beautiful. if you don't want a sparkly setting, you can get a stone set in a cabachon...that is an unfaceted flat stone in a picture frame-type setting. i don't like them, as they don't sparkle. also depends on the quality rating of the stone: AA, A, B, etc. i think they look much better set in sterling silver rather than gold, and much less expensive too. there are many websites you can go to, to see different gem stones...google it. hope this helps. ;)

Answer 4

thats because the impurity in its crystals
its a berilium crystal, its formulae is Be3Al2(SiO3)6. the berilium crystals are transparent, but its impurities are cromium and vanadium are the origin of the green shine
