Shop by Gemstone Category
Select Your Spark. Whether you’re feeling the cold fire of a Diamond or the moody depths of a Sapphire, we have a stone for every version of you. Shop by gem and find your signature glow.
Two ways to Shop
Most gemstone shops choose between “Retail” or “Trade-Only.” At Gem Fountain, we make both
accessible with full transparency — directly from the Chanthaburi gemstone market.
Two service levels: a refined, curated selection and genuine trade parcels sold as traded.
Classic & Fine Gems
Jewelry-ready gemstones, carefully selected and refined for setting performance — from classic everyday favorites to truly exceptional stones.
- Professional finishing: polish, symmetry and proportion
- Single stones, matched pairs, sets & layouts
- Market-sourced, then refined in-house where beneficial
- Classic gems (cabochons and popular varieties), plus Fine Gems — rare, collector-grade
highlights - Best for jewelers and collectors seeking ready-to-use quality
or high-end exceptional stones
Market Direct & Wholesale
A genuine parcel-buying experience. Market Direct gives buyers access to trade parcels, lots & rough stones — sold as traded and priced often significantly below retail-equivalent single stones.
- Trade parcels, lots & rough stones at the lowest possible price-per-carat
- Native cuts and mixed cutting quality directly from the market
- Mixed goods: some stones are jewelry-ready, while others offer re-polish or recut potential
- Get exactly what the market offers, without refinement markups
- Ideal for dealers, cutters, jewelers and manufacturers sourcing for production or value opportunities

Integrity in Every Facet.
Built for the trade.
In a market flooded with ambiguity, we provide the clarity and provenance professional jewelers require to sell with absolute confidence.
Ethical Sourcing & Origin
We work with trusted suppliers, direct market channels, and long-standing trade relationships. Origin information is disclosed honestly where known or documented. We do not make unrealistic mine-to-market claims for every gemstone — instead, we clearly state what is known and what can be supported.
Long-term Supplier Relationships
Our work is rooted in Chanthaburi’s gemstone trade and supported by long-standing family and supplier relationships. These connections give us access to a wide range of gemstones, cutting services, and market-direct opportunities — with trust built through years of fair trading.
