December, Tanzanite

Believed to have mellowing properties

Tanzanite: Tanzanite, the ultimate prize of a gem safari, has a mesmerizing blend of rich purples and blues with a velvety deepness of color unlike any other gem. Mined only in Tanzania at the foot of the majestic Mount Kilimanjaro, virtually every tanzanite is heated to permanently change its color from orange-brown to the spectacular violet-blue color for which this precious gemstone variety is known.

Legend has it that the effect of heat was first discovered when some brown gem crystals lying on the dry earth were caught in a fire set by lightning that swept through the grass-covered hills. The Masai herders driving cattle in the area noticed the beautiful blue color and picked the crystals up, becoming the first tanzanite collectors.

December, Blue Topaz

Symbol of love and fidelity

Blue Topaz: Topaz sometimes has the amber gold of fine cognac or the blush of a peach, and all the beautiful warm browns and oranges in between. Some rare and exceptional examples are pale pink to a sherry red. Sometimes peach-colored topaz can be pinked by gentle heating. This color change is permanent.

Blue, once the most rare color of topaz, is today the most common, thanks to diffusion, a stable enhancement process that turns colorless topaz blue. This enhancement process is permanent.

Topaz is a very hard gemstone, but it can be split with a single sharp blow, a trait it shares with diamond. As a result it should be protected from hard knocks. Clean with mild dish soap; use a toothbrush to scrub behind the stone where dust can collect.
