Tiffany named the gem in his honor: kunzite.

In the mix of pieces, some of which have a butterfly design, is this diamond and kunzite crystal necklace.

The family that provides her kunzite were her neighbors in San Diego until they moved to their native Afghanistan.

Jewelry made with pastel-colored gems like kunzite, paraiba tourmaline and mauve spinel plays a supporting role to diamond pieces.

Of growing importance are the gems found in California: a few diamonds in Butte county; rock crystal in Calaveras county; and tourmalines, kunzite, the rare pink beryl and bright blue topazes in San Diego county.
