Light Of The Desert
The Light of the Desert is the world’s largest faceted cerussite gem, weighing . It is currently part of the collection of the Royal Ontario Museum (ROM) in Toronto. The raw cerussite was discovered in Tsumeb in northern Namibia. It was then acquired by a gem cutter from Arizona, who cut the raw material into the gem on display. Cerussite is extremely fragile and sensitive to temperature changes and vibration; cutting and transport of the gem therefore causes significant problems. After it was cut in Arizona, the gem was placed in a box, then wrapped in a large woolen scarf and a winter vest, and then hand transported to Toronto Toronto ( ; or ) is the capital city of the Canadian province of Ontario.

Cerussite
Cerussite (also known as lead carbonate or white lead ore) is a mineral consisting of lead carbonate (PbCO3), and is an important ore of lead. The name is from the Latin ''cerussa'', white lead. ''Cerussa nativa'' was mentioned by Conrad Gessner in 1565, and in 1832 F. S. Beudant applied the name ''céruse'' to the mineral, whilst the present form, cerussite, is due to W. Haidinger (1845). Miners' names in early use were lead-spar and white-lead-ore. Cerussite crystallizes in the orthorhombic crystal system and is isomorphous with aragonite. Like aragonite it is very frequently twinned, the compound crystals being pseudo-hexagonal in form. Three crystals are usually twinned together on two faces of the prism, producing six-rayed stellate groups with the individual crystals intercrossing at angles of nearly 60°. Crystals are of frequent occurrence and they usually have very bright and smooth faces. The mineral also occurs in compact granular masses, and sometimes in fibrous fo ...
