Saturation in color for amethysts is a very desirable and sought feature. The finest amethysts possess an intense purple tone, which is scarce throughout the world, and of nearly no visible color zooming. Due to the mineral nature of this quartz variety, you’ll find different shades within every crystal on the geode, however, homogeneity is very valued in amethysts.

Only high-quality amethysts can expose visible cut stalactites, which are rare and they can adorn the piece and embellish it stunningly and uniquely. The presence of a cut, polished stalactite resembles an “eye” or “flower” and they add a natural design and detail of brilliance.
Calcite formations are also relatively rare, therefore scouted out by collectors or buyers looking for more components as they reflect the extraordinary implication of different temperatures required for the two minerals to crystallize.
The presence, or not, of layers or bands in the agate bordering reaching the basalt back shell can add to the uniqueness of the piece. Each layer developed in a distinct period of its formation process and they possess different mineral impurities and compositions.

The merger of factors all contributed to a particular look that separates the piece from any other. Celadonite in multicolor shades of bluish, greenish, orange, and yellow to even vibrant green and blue shades around the borders accentuate the brilliance of purple amethysts remarkably.
