Product Description
This listing is for a 100-carat parcel of natural rough tourmaline crystals sourced from Afghanistan — one of the world's most recognized origins for multi-color tourmaline. The lot contains 42 pieces with individual crystal weights ranging from under 1 carat up to 11 carats, averaging approximately 2.3 carats per piece.
The crystals display the characteristic trigonal prismatic habit of tourmaline, with visible striations along the length of each piece. Colors in this parcel include pink, light pink, apple green, light green, indicolite (blue-green), lavender, red, and colorless — several pieces show bi-color zoning within a single crystal.
Lot Specifications:
- Stone: Tourmaline (Semi-Precious, Natural Gemstone)
- Origin: Afghanistan
- Total Weight: 100 Carats (42 pieces)
- Individual Sizes: Under 1 ct to 11 ct (avg. ~2.3 ct)
- Shape: Rough prismatic crystals, natural loose shapes
- Clarity Range: Transparent to Included (VVS, VS, SI, and Included grades present)
- Treatment: 100% Natural – Untreated, Earth-Mined
Suitable Uses:
- Faceting & Lapidary: Cleaner, more transparent pieces in the lot are suitable for faceting into small gems. Sizes up to 11 ct offer workable rough for beginner and intermediate cutters.
- Cabochon Cutting: Included or opaque pieces can be shaped into cabochons for use in silver or wire-wrap settings.
- Crystal Collecting: Several pieces retain natural terminations and prismatic form, making them suitable for mineral specimen collections.
- Raw Stone Jewelry: Smaller crystals are usable as-is for wire-wrapped pendants, raw crystal rings, or healing jewelry.
This is a mixed-grade parcel — not all pieces are facet-grade. The lot is sold as shown, and the variety of clarity grades and colors reflects the natural distribution of rough from this source region.
Frequently Asked Questions
Q: What is the difference between facet-grade and collector-grade tourmaline rough?
Facet-grade rough is transparent with minimal inclusions, allowing it to be cut into faceted gems. Collector-grade pieces may have inclusions or interesting crystal form but are valued for their natural appearance rather than cutting potential.
Q: Can Afghan tourmaline rough be used for wire-wrapped jewelry without cutting?
Yes. Small raw tourmaline crystals with natural terminations are commonly used in wire-wrapped pendants and rings without any lapidary work. Pieces under 3 carats in this lot are well-suited for that purpose.
Q: How is tourmaline rough graded — what do VVS, VS, SI, and Included mean for raw crystals?
These clarity grades indicate the level of internal inclusions visible to the eye or under magnification. VVS and VS pieces are largely transparent with few inclusions; SI pieces have visible inclusions but remain partially transparent; Included pieces are heavily fractured or opaque.
