3.18 Carat Hexagonal Rough Emerald Crystal | Faceting Rough

This is a single natural emerald crystal weighing 3.18 carats, mined from the Swat Valley, Pakistan — one of the world's historically significant emerald-producing regions. The crystal displays a vivid green color with a semi-transparent body and retains its natural hexagonal prismatic form. The stone is classified as 100% natural and earth-mined with minor oil treatment only — a standard, accepted practice in the emerald trade used to improve surface clarity. No resin, no fracture filling, no synthetic enhancement. Condition is rated Good (G) with clarity graded SI / Semi-Transparent. Mineralogically, this is a member of the Beryl family (Be₃Al₂Si₆O₁₈) crystallizing in the hexagonal crystal system. The natural prismatic termination is partially intact, making it suitable for both faceting and display. Stone Details Stone: Emerald (Beryl) Weight: 3.18 carats Shape: Hexagonal (natural crystal form) Clarity: SI / Semi-Transparent Crystal System: Hexagonal Origin: Swat Valley, Pakistan Treatment: Minor Oil (100% Natural, Earth-Mined) Product Use: Faceting Rough · Lapidary · Collector Specimen Suitability This piece is listed under Facet Rough, Raw Crystals, Lapidary Rough Stones, and Crystals for Collectors. The semi-transparent body and vivid saturation make it a viable candidate for custom faceting into a finished gemstone. Collectors may also retain it as a natural mineral specimen given the intact hexagonal habit. Frequently Asked Questions Q: Is Swat emerald the same quality as Colombian emerald? Swat (Pakistani) emeralds share the same mineral species (beryl) and can exhibit comparable vivid green color, though Colombian stones typically command higher market premiums due to brand recognition. Pakistani emeralds are valued for their strong saturation and direct-source availability. Q: What does "minor oil" treatment mean for an emerald? Minor oil means a small amount of colorless oil or resin was used to fill surface-reaching fractures, improving transparency. It is the most accepted and least invasive treatment in the emerald trade and does not affect the stone's natural classification. Q: Can a rough emerald crystal be faceted into a finished gem? Yes — rough emeralds with sufficient transparency and saturation are routinely cut by lapidaries into faceted stones. The yield depends on the clarity, inclusions, and shape of the rough; SI-clarity material like this piece is commonly used for custom cuts.
