Amethyst heart in metal stand with large dark crystals

An amethyst heart in a metal stand from Brazil with large, dark crystals. The internal crystallography is distinctly large, and the color is deeply saturated.

Deep iron substitutions produce the dark coloration. Long, stable growth phases are responsible for the large individual crystals. Both properties together constitute a double gemmological premium mark.

The heart-shaped cut frames the internal crystals in a symbolic ornamental form. The metal stand fixes the heart in an optimal upright viewing position.

Brazilian deposits in Rio Grande do Sul supply the premium raw materials for such heart cuts. The sharp contour of the individual crystals against the polished outer edge is striking.
