This extra large piece hosts 2 generations of Calcite: the first generation is featured on the front which is a layer of bright white, highly lustrous Calcite crystals, and then on the side and back is a second generation of beige colored microcrystalline Calcite...

Really interesting piece: Several small Calcite crystals dusted with microcrystalline Quartz deposited on a plate of Amethyst Quartz crystals, also dusted with microcrystalline Quartz. This makes for incredible luster, great contrast and an unusual yet intriguing, eye-catching piece - I have yet to see...

This piece has great contrast with translucent to transparent lenticular Calcite crystals on a dark matrix. The Calcite crystals, especially the ones in front, are pristine and gemmy,  while the one in back has several Stibnite inclusions (see pics). This is an attractive and...

An elongated Calcite crystal with multiple terminations. Great luster and color and no damage. Location: Yunnan Province, China Size: 9.8 x 3.2 x 1.8 cm

A showy cluster of Sphalerite crystals on quartz, with red microcrystalline quartz crystals intermingled with, and in some instances, coating several of the Sphalerite crystals, along with numerous Calcite crystals populating the piece, especially the back. The Sphalerite crystals are a deep reddish-brown (see...

Great contrast - there is of course the golden, almost transparent lenticular Calcite crystals on a matrix covered with miniature white translucent scalenohedral Calcite crystals. If that’s not enough, near the front you’ll see Stibnite crystals intermixed with the matrix. Great piece with no...

This piece has one large, amber colored, translucent, complex Calcite crystal with a soft, waxy luster (due to the striations noticeable on the closeup pic) situated on a bed of smaller like-colored Calcite crystals. I have rarely seen a Calcite crystal this flawless and...
