Intensity of color is very desirable and a sought feature. The finest amethysts possess a strong purple tone with nearly no visible color zooming. Saturated color is preferred, as it can be more uncommon, only the highest quality amethyst will posses it. Visible cut stalactites are rare in amethyst and they can adorn the piece and embellish it in a stunning and unique way.

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 time period of its formation process and they possess different mineral compositions and impurities. These factors all contributed to an 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. Due to the mineral nature of this quartz variety, you’ll find different shades within every crystal on the geode, however, homogenenity is very valued in amethysts.
