Rough Emerald Crystals
This lot consists of approximately 18 individual rough emerald crystals, displayed on a white paper surface with a handwritten annotation indicating a total weight of 115 carats. The gemstones exhibit a characteristic vibrant, deep green saturation typical of high-quality emeralds. Physically, the crystals display a variety of natural hexagonal prismatic habits, which is the standard crystal system for beryl. Sizes appear to vary from roughly 5mm to 12mm in length. The clarity ranges from translucent to semi-opaque, with visible internal inclusions, fractures, and 'jardin' (garden-like) patterns common in natural emerald specimens. Some crystals show flat basal pinacoid terminations, while others appear more fragmented or water-worn. Surface textures vary from shiny, glassy facets to duller, matted areas where host rock matrix or surface reach-in inclusions are present. Darker inclusions, possibly biotite mica or pyrite common in certain origins like Colombia or Zambia, are visible in several pieces. No evidence of oiling or resin treatment can be confirmed from the image alone, though such treatments are standard in the trade. The stones are in their natural, unpolished state, showing sharp edges and raw geological formations indicative of high-quality mineral specimens suitable for lapidary work or mineral collecting.
