Long, slender crystal of laboratory grown Quartz.  This came from an old collection that had lots of 1980s era specimens, though the exact date of when it was grown is unknown but likely dates back to the 1950s when these were grown for the telecommunications industry.  It's water clear and pristine with dimpled/wavy surfaces over the prism faces and flat, glassy termination faces.  These were grown between two metal pins and each tip has a small indentation cuased by the pins.  Rare historic specimen.

Glassy white Datolite crystals on matrix. Found by a friend while prospecting in this area known for Jadeite and Rosenhahnite crystals. These were found in a single boulder that was excavated during construction work on Highway 101. This boulder produced what are considered Californias's best Datolite. Individual crystals on this specimen reach 7mm in size and are translucent to transparent. Superb piece for a California suite of minerals.

Smokey Quartz cluster on Microcline with a terminated green Tourmaline crystal projecting out near the base of the Quartz. The Quartz have an unusual and intersting 'spotted' appearance due to radiation halos from Uranomicrolite. There are also Tourmaline included within the Quartz. Ex. Cal Graeber collection with his number on back.  Cal used to work with Bill Larson when he owned the mine and is a true San diego county expert.  The fact that he kept this specimen in his collection speaks for it's rarity and quality.

Large, dark green single Tourmaline crystal from recent production at this famous mine in Zimbabwe. Tourmaline has been very rare from this mine historically, which has primarily targeted blue Topaz. Most Tourmaline found here occur as small pencil-like crystals and this fat, somewhat tabular crystal in an anomaly. Though dark, it is transparent facet grade throughout with a more greenish brown at the upper third and a bright pure green in the lower two thirds. There is a bit of edge chipping along the sides, it's complete all around, and has a perfect termination. Weighs a hefty 153 grams.
