Emeralds are hard to not like. Such a verdant green.

Jadeite ..... USD $3 + Million/Carat

jadeite-tm-1.jpg


Until recent years jadeite has been something of a mystery mineral, but we now know of primary sources in Guatemala as well as several California occurrences of white or grayish jadeite. Boulders in which a few small freestanding crystals have been seen occur in San Benito Co., California, with additional finds in Clear Creek, between New Idria and Hernandez. All Mexican jadeite is in artifacts, from unknown sources. The record price for a single piece of jadeite jewelry was set at the November 1997 Christie’s Hong Kong sale: Lot 1843, the “Doubly Fortunate” necklace of 27 approximately .5 mm jadeite beads sold for US$9.3 million

MOAR! Today is the desert rose.

Desert rose is the colloquial name given to rosette formations of the minerals gypsum and barite with poikilotopic sand inclusions. The 'petals' are crystals flattened on the c crystallographic axis, fanning open along characteristic gypsum cleavage planes.

The rosette crystal habit tends to occur when the crystals form in arid sandy conditions, such as the evaporation of a shallow salt basin. Gypsum roses usually have better defined, sharper edges than barite roses.
