Our Rough Gemstone Collection
Our Rough Gemstone collection is curated for makers who value gemstones in their natural, organic state. From raw Emerald and Ruby to earthy Amethyst and Apatite, we supply rough gemstones suitable for wire‑wrapping, lapidary work, and statement “raw” jewellery designs.
The MGB Photo Guarantee
Every rough stone product is photographed individually. Because raw stones are defined by their natural growth patterns, inclusions, and surface fractures, we show the exact product you are buying. We do not use stock images or idealised specimens — each photo reflects the true geometry and colour of your specific product.
Geological Variety
Precious Rough: Natural Ruby, Sapphire, and Emerald for high‑value organic designs.
Semi‑Precious Rough: Apatite, Citrine, Garnet, Kyanite, and other minerals selected for structural integrity and natural colour.
Practical Sourcing for Makers
Our rough gemstones are organised by weight and size, allowing you to select the scale needed for your project. Whether you need small accent pieces or larger focal stones, our high‑resolution images provide the detail needed to assess suitability for your design.
Straightforward Representation
We photograph all rough stones dry and under natural lighting to show their true “as‑mined” character. This transparency ensures you can evaluate texture, structure, and internal features before the stone arrives at your workshop.
