Zoisite (Var: Tanzanite) : {Ca₂}{Al₃}[O\|OH\|SiO₄\|Si₂O₇]
	Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania This is a superb thumbnail of a gemmy, lustrous, tanzanite crystal, displaying tri-chroism (three disparate colors: purple, blue, red, each in a different plane). The third color is the proof of natural coloration - the treated ones do not have red on the long axis. 2.2 x 1.6 x 1 cm (40 carats)

Zoisite (Var: Tanzanite) : {Ca₂}{Al₃}[O\|OH\|SiO₄\|Si₂O₇]
	Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania What can i say that the pics do not except that this is BETTER in person, of the very top quality for deep color and intense dichroism! It is glassy and gemmy as hell! Crystals like this, with such obvious facet rough value, are becoming incredibly hard to come by now as the supply of rough dwindles. Given the government monopoly on facet rough ...

Zoisite (Var: Tanzanite) : {Ca₂}{Al₃}[O\|OH\|SiO₄\|Si₂O₇]
	Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania This fantastic, impressive crystal is so glassy and clean that you can EASILY read right through the whole thing, and it is brilliantly lustrous and colorful to boot! It is one of the finest-quality crystals of ANY SIZE that I have seen. It is so clear and clean that it shows off its gemminess in even minimal lighting, no backlighting required at ...

Zoisite (Var: Tanzanite) : {Ca₂}{Al₃}[O\|OH\|SiO₄\|Si₂O₇]
	Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania A VERY sculptural, glassy, lustrous, bright crystal with superb aesthetics! It is VERY gemmy and transparent in most parts. It shows excellent blue and purple colors along the a and b axes, but the c axis shows no red or brown hue, indicating that it is a crystal treated by heat to enhance the natural blue tones. 3.3 x 2.6 x 1.5 cm

	Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania A superb, gem-quality Tanzanite that demonstrates the classic color change along a and b axes. It is exceedingly glassy and gemmy! It should have a relatively high yield in stones from the large central zones. 2.2 x .9 x .6 cm (13 carats)

Zoisite (Var: Tanzanite) : {Ca₂}{Al₃}[O\|OH\|SiO₄\|Si₂O₇]
	Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania A specimen of surpassing quality, with both gemminess and GEM VALUE going for it. This is a NATURAL tanzanite without having been heated to enhance the blues at the expense of the red hue. This piece is the most strongly trichroic tanzanite crystal I have ever had to offer. It glows with rich colors: blue, purple, and particularly red/maroon along ...
