A very attractive Datolite cluster the color of which includes green, yellow, green/yellow, blue/green and yellow with a slight orange tint. There are two generations of Datolite crystals with smaller crystals having grown on larger crystals. The largest underlying crystal is approximately half the size of the overall specimen. On the surface of the Datolite, there are unusual shaped Quartz crystals with a narrow habit. The shape was caused by the Quartz growing in layers with Calcite which later dissolved. The dissolved Calcite has also left pseudomorphic casts on the surfaces of the Datolite. These casts are in the shape of thin, parallel orientated grooves. The Quartz is smoky colored in places and white elsewhere. The surfaces of the Datolite have a high, glossy luster. In places, the upper layer of the Datolite is gemmy.

Condition: Excellent

Flaws: Nothing Appreciable
