Jadeite Jade has been known and treasured for more than 7,000 years. But only in 1863 was it discovered that jade is actually not a single mineral. What was traditionally called jade is in fact two separate and distinct minerals: jadeite and nephrite.
Nephrite is the more common form of jade. Nephrite ranges in color from mid- to dark-green or grey-green, but it can also be white, yellowish or reddish. Nephrite is slightly softer than jadeite; nephrite is 6-6.5 on the Mohs scale, while jadeite is 6.5-7. They have quite different chemical compositions as well; nephrite is a calcium magnesium iron silicate while jadeite is a sodium aluminum silicate. The two minerals also have different densities. Jadeite has a density of 3.30-3.38 while nephrite is less dense at 2.90-3.03.

In my 20's I imported gemstones. I decided to try it again, for gifts. I found GemSelect; studied their website; talked with them and decided to make a purchase.
I would recommend GEMSELECT based upon the variety of gems. Gems that i didn't expect to even be apart of the selection and it gave me more options. Options in which played a key role in finding the right gem. Its always good to have options especially when trying to formulate a good piece of art work that has uniqueness. Which ultimately captures costumers eye appeal.
Gemselect is o.k the prices are pretty good, but the shipping prices really suck, one time I order from them and order got lost or never came, but they were good about fixing the problem and rectifying the situation, the stones and good, and the ones that come in the mail, look just as pictured on the website, or all it's not bad and its were I go to get my stones.
