Item Description

This emerald matrix specimen has excellent form, composition and contrast with the modified, well-formed Calcites providing the perfect association. A classic Colombian emerald crystal, but unusual in that it is nestled softly in "mountains" of sharp white calcite crystals, providing a beautiful contrast of two crystallized species instead of the usual host rock only! The 1.6 cm Emerald on this piece is of top color, glassy luster and good translucency (translucent but not transparent). This gorgeous Emerald crystal is nestled in with a trio of large, translucent, white to off-white, modified Calcite rhombohedra to 2 cm, along with a few smaller Calcite crystals. The Emerald crystal exhibits an intense green color and is quite gemmy with only moderate internal fracturing and a part of the top termination is evident. The larger Calcites exhibit an almost opalescent glow to them at the interior and compliment the emerald well - so the combination really acts to improve the beauty together more than either species alone. The piece sits nicely on its own for display. Illustrated in Mineral Collections of Brazil, 2020, page 131, shown in the personal collection of the multigenerational Gioia family of collectors (from Sao Paolo).
