Spherical Amethyst (''grapes'')

Item Description

This is a good cabinet-sized piece of these distinctly unique Amethyst specimens from the recent discovery in Indonesia. Quartz can be called the most diversified species in the world (found in a wide variety of styles, habits and colors), but we still see new material that is unlike anything we've encountered before. Here we have a beautiful example of these unique specimens from Indonesia which are commonly referred to as "Grape Agate" or "Grape Chalcedony" for obvious reasons. They are fairly new to the market, and they are singular as they do not resemble any other Quartz specimens we've seen. They actually are not Agate or Chalcedony, but in fact they are micro-crystallized on the surface, so this is not a cryptocrystalline variety of Quartz, this is truly purple crystallized Quartz = Amethyst. The pieces were analyzed by Dr. George Rossman at CalTech and determined to be Amethyst due to the micro-crystallization.

As you can see, these specimens got their nickname due to the fact that they are purple and genuinely resemble bunches of grapes. Very little of this material seems to be out there now, and perhaps it is drying up. If you missed out on these when they first came out, this is a great opportunity to pick up a really attractive specimen for a great piece. This piece is filled with excellent, translucent, sparkling "balls" or spheroids measuring up to about 4 mm which are tightly intergrown and are visible literally on every side of the specimen. The color is a pleasing medium purple hue, with green tones due to Celadonite inclusions in spots. There is a lot of Quartz in the world, but these pieces are truly unique and would make a great addition to any Quartz suite.
