Pietre preziose cromo
Chrome gems are colored by traces of chromium, giving them a beautiful green color. Chrome green gems can range from bright green to deep forest green. Chrome gem varieties include chrome diopside and chrome tourmaline, which are available in various sizes, shapes and cutting styles.
Chrome diopside is colored by chromium and displays a rich forest green that has similarities to tsavorite garnet and chrome tourmaline. While not seen in mainstream jewelry stores, diopside is becoming more and more popular with jewelry designers for its intense deep green color. It is not a particularly hard stone, however (Mohs rating of 5.5-6.5), so it is best used for earrings, pins and pendants.
Chrome tourmaline is a distinct variety of tourmaline called chrome dravite, found in East Africa. Chrome tourmaline owes its vivid green hue to trace amounts of chromium and vanadium. These are the same elements that give emerald and tsavorite garnet their distinctive pure green hues. Like emerald and tsavorite garnet, fine chrome tourmaline is a visually pure forest green with slightly yellowish to bluish secondary hues. The blue will normally show itself in incandescent light, the yellow will be more visible in daylight. A blue secondary hue is preferred to yellow. Chrome tourmaline is quite rare generally, and particularly rare in sizes over one carat. A stone of fine quality over one carat is very rare. Therefore, the collector should expect a large percentage increase in the price of stones in carat-plus sizes.

I always check this site because they have unique options.
I ordered this really nice pair of Rubies from Gemselect and I love them because of all the detailed information you get. Also if you scroll down you can see other similar items single, in pairs, lots, bigger, smaller, etc and it's such an easy website to use.
I wasn't sure where to go to find a variety of gemstones to choose from in the size and shape that I was looking for. I'm really glad I found this website because the search options and filters made it really easy to find what I was looking for. The prices seem quite reasonable. This will be the first place I go the next time I'm looking for a gemstone!
