From the zone in Brazil famed for Amethyst geodes, this is something very different from almost any other Quartz. A pair of spindle-like growths of Glauberite that has been altered to and overgrown by Quartz. These are perfect, complete all around, with tiny transparent smokey Quartz sparkling on all sides.

Simply a very esthetic and unusually well formed piece. The "flower" is 7 cm in diameter and the individual "petals" reach 3.8 CM. The color is a gradation from light to dark purple and the whole sits neatly on a quartz matrix. Excellent condition and showy. Irai has been a very prolific location so good specimens can still be found for a reasonable sum. This is well above average for quality and a very good value.

Two perfect radiating clusters (suns) joined together in an impressive and esthetic piece of glass-like Quartz. No damage at all, a fine purple hue that grades to a clear outer edge the piece is fully transparent and glows with even a hint of backlight. Not the typical quality, this is a fine mineral specimen for a fine collection.
