C-256  Corundum  SOLD

Yinnietharra, Upper Gascoyne Shire, Western Australia, Australia

8 x 3.9 x 1.4 cm

Although technically not a Sapphire, I could not let this update go without this amazing colorless crystal.  One of Australia's most well-kept mineral secrets are the singular crystals from Yinnietharra.  The unusual form of these specimens are due to twinning which are sometimes referred to as "Angels.  The gentleman that I purchased this crystal from said it reminded him more of a cuttlefish than an angel.  Whatever it looks like to you; these oddities add credence to the statement: “some rocks are more unique than others.”

C-257  Corundum variety Sapphire  SOLD

San Jacinto Mountains, Riverside County, California

5.6 x 4.3 x 1.3 cm

Here's another strange-looking Sapphire that I acquired from a friend a while back.  The spot in the San Jacinto Mountains where Sapphire is found is renowned for it's tapered prismatic crystals which can be quite large in size.  Every once in a while these flattened Sapphires are encountered.  This bi-colored specimen still has a bit of Mica attached to it.  I believe that the grooves in the specimen are where Mica was once present.  A neat mineral oddity in my opinion.

N-003  Natrolite in Basalt  SOLD

Wasson Bluff, Parrsboro, Cumberland County, Nova Scotia, Canada

10.1 x 8.4 x 3.7 cm

This attractive specimen consists of a slab of Basalt which has a 4 x 3 cm wide vug that is lined with many sprays of acicular crystals of Natrolite.  The Natrolite sprays are peach-colored at their base and almost clear the rest of their length giving them an almost satin-like appearance.  Specimens from Wasson Bluff are hard to come by, as digging in the cliff area is allowed by permit only.

Sugilite, N'Chwaning II Mine, South Africa

S-150  Sugilite  SOLD

N'Chwaning II Mine, Kuruman, Kalahari Mn Field, Northern Cape Province, South Africa

10.4 x 6.3 x 4 cm

A very colorful specimen of the rare mineral, Sugilite.  The matrix of this specimen is covered by a a mat of coarsely formed, vivid purple, Sugilite crystals.  Sugilite is very rare, being found at a dozen or so locations worldwide.  Sugilite is an example of a mineral name pronounced wrongly more often than correctly. Named after Japanese petrologist Dr Kenichi Sugi, whose name is pronounced with a hard "g" (as in "geese"), whereas most english speakers mispronounce it with a soft "g" (as in "gene"). This wasn't much of an issue when sugilite was just an obscure ugly greenish-yellowish-brown rock-forming mineral from Japan, but when it was found in South Africa as large quantities of bright purple lapidary rock and thousands of people in the gem trade started talking about it, the bad pronunciation became entrenched.
