For example, G10 garnets, a type of garnet typically found in diamond-rich pipes, are lower in calcium and higher in chrome than garnets from barren pipes.

例如，G10 石榴石，一种通常发现于富含钻石的管道中的石榴石，与无钻石管道中的石榴石相比，其钙含量较低，铬含量较高。

It features a pear-shaped D color, type IIa diamond of 15.31 cts. and VVS2 clarity before.

FORBES: 30.52-ct. emerald-cut diamond sold for $3.3 million.

Gemesis colorless diamonds are all certified as Type IIa, the purest type of diamond, almost or entirely devoid of chemical impurities.

Adding to their allure is that they have also been determined to be Type IIa, the most chemically pure form of diamond showing exceptional appeal transparency.
