It is hard to find a good cluster of Danburite. Usually we see them as single crystals, and occasionally as large clusters, usually damaged. This cluster is quite aesthetic as the crystals shoot off in many directions. Near the base of the crystals are reflective Chalcopyrites. Danburite is found in a Tin Mine in Mexico. The miners that bring them out are apparently quite rough with them, as seen by very common damage. This piece is in good shape overall. the largest 15 crystals are fully intact, there is a stub or two, but you have to look for them.  

SPINEL3 - Blue Spinel in calcite with Mica
$ 125.00 (=~ ¥ 18452.31) SOLD
Rift Valley Province, Kenya
small cabinet - 7.3 x 7.1 x 4.3 cm

This is a large specimen showing over a dozen blue Spinels embedded in calcite, and contrasted by scattered sheets of mica. This piece really shows the layer well. It's in good condition, and some of the crystals are very gemmy.

DATOLITE1 - Datolite with Quartz
$ 65.00 (=~ ¥ 9595.20)
Dalnegorsk, Primorskij Kraj, Russia
miniature - 4.4 x 3.7 x 2.8 cm

This bright twinned Datolite is perched alongside a cluster of Quartz crystals. Many Datolites from this location are either dark and blocky or so light in color as to seem invisible. This example has a slight green tint. Some of the quartz crystals have broken off, but the centerpiece is the Datolite, which is in great shape (very tiny chipping along an edge, seen with loupe).

QUARTZ16 - Quartz var. Faden
$ 235.00 (=~ ¥ 34690.35)
Dara Ismael Khan District, Waziristan, Pakistan
cabinet - 13.3 x 4.8 x 4.3 cm

This spectacular Faden Quartz is an excellent example from the original find in Pakistan. I grabbed this piece along with a few other fine examples from an italian dealer who was the first broker of this find about 12 years ago. It shows the white stripe of the "thread" (in German: Faden) well, it has great clarity, no damage. It is tall and is on matrix.

TOPAZ5 - Topaz
$ 65.00 (=~ ¥ 9595.20) SOLD
Minas Gerais, Brazil
miniature - 3.6 x 2.4 x 2.0 cm

Here is a solid, blue topaz crystal. It was the best crystal from a lot purchased years ago. It is undamaged, it has some natural etching that makes it interesting. It weighs 32.5 grams.

"5d" pic is a top down image. It looks a lot bluer in low light, as it is mostly transparent.
