17.2 x 9.4 x 2.7 cm. This plate of intergrown fluorite has crystals reaching 2.1 cm across. Oddly, the crystals have opaque, purple cores which are not in the symmetrical plane of the larger crystal growth. The sharp phantoms are cubic, and are 45 degrees rotated from the peripheral edge symmetry. All the crystals have lighter lavender colored edges which are very translucent.
13.6 x 11.6 x 2.7 cm. This plate of intergrown fluorite exhibits rich emerald green color along with lavender color zoning, caused by internal phantoms. Crystals reach 2.3 cm across and most of the crystal corners are colorless.
12.5 x 10.7 x 2.4 cm. Lustrous and translucent, this intergrown fluorite plate exhibits stepped growth and rich, emerald-green color which is perhaps better in person. Crystal growth reaches 5.3 cm across. Oddly, one or two specks of rich lavender color emanate from deep in crystal cores. Most of the cores though, are a darker green phantom growth, offset at 45 degrees to the larger crystal in which they reside.
9.6 x 9.3 x 6.3 cm. Large, blocky, cubes of fluorite, with stepped growth on the corners, exhibit a rich emerald green color at their cores and a lavender color at the corners. The crystals reach 5 cm or 2 inches across and are robust. The complexly stepped edges of the largest top and frontal cubes show wonderful complexity, highlighted by a purple color.
3.5 x 2.7 x 2.1 cm. This single crystal of lustrous and translucent emerald green fluorite has dark lavender spots in each corner.
4.2 x 3.8 x 1.3 cm. Not only is this translucent fluorite specimen strangely color zoned, most of the darker lavender core is oriented in a direction 45 degrees offset to the plane of the crystal, making a stark contrast of both color and form within the same crystal.
7.3 x 6.0 x 1.4 cm. This intergrown plate of fluorite is lustrous and highly translucent. The predominant color is intensely purple cores, but with colorless areas around them. The internal phantoms are oriented in a direction 45 degrees from the plane of crystal growth around them. Crystals reach 1.8 cm across.
6.9 x 4.4 x 1.7 cm. This is an aesthetic plate of well formed, intergrown fluorite crystals, with the largest crystal, 2.0 cm across, perched at the very top of the specimen if stood vertically. It has good luster and translucence with a rich lavender color supported by colorless areas and opaque lavender cores which are oblique to the plane of crystal growth.
7.9 x 5.2 x 1.5 cm. A large fluorite crystal measuring 2.3 cm across is perched high between smaller intergrown fluorite crystals. Good luster and translucence and a rich lavender color is augmented by colorless areas and opaque lavender cores which are oriented 45 degrees to the plane of crystal growth. Sharp phantoms.
12.2 x 6.4 x 1.9 cm. An overall color of rich lavender, along with good luster and exceptional transparency highlights this plate of intergrown fluorite. Crystals reach 1.0 cm across and many have darker, opaque color centers not oriented in the plane of crystal growth but rather offset at 45 degrees, producing a stark contrast in form and color both.
6.4 x 6.0 x 1.1 cm. This thin plate of lustrous and translucent, intergrown fluorite is highlighted by crystals that have a rich lavender color interspersed with colorless areas. Crystal size reaches .7 cm across. Exceptionally gemmy and translucent.
6.6 x 5.1 x 1.6 cm. Having primarily a rich lavender color along with colorless areas and dark lavender color centers (sharply set at 45 degrees to the surrounding crystal faces), this plate of intergrown fluorite crystals is lustrous and translucent. Crystals reach 1.0 cm across.
10.7 x 5.7 x 2.2 cm. This cluster features intergrown, translucent, fluorite crystals, to 1.5 cm across, of a variegated, light and dark lavender color. Many of the darker, opaque lavender cores are not oriented in the plane of the crystals, but stand dramatically out in form as they are 45 degrees off angle from the surrounding crystals in which they are phantoms.
9.4 x 8.0 x 3.4 cm. Lustrous and translucent, intergrown fluorite crystals, to 2.25 cm across, exhibit variegated light and dark lavender colors with really fun patterning. Sharp phantom lines are seen in many crystals. Crystals with lighter colored lavender phantoms are clearly evident.
4.8 x 4.5 x 1.9 cm. An extremely sharp, jigsaw-arranged cluster of variegated, intergrown fluorite crystals, to 1.5 cm across, exhibit luster and translucence. The colors range from light to dark lavender, and color zoning is clearly evident in many crystals.
