Description:
• 18CT WHITE GOLD CASTING GRAIN •
Our 18ct white gold casting grain offers jewellers a reliable, high-quality material for custom casting applications. Each granule is precisely refined to ensure consistent alloying, excellent flow characteristics, and minimal porosity during the casting process. Available in bulk for professional use, it's ideal for jewellers seeking reliable, ethically sourced gold for casting projects that require precision, durability, and a professional finish.
• KEY POINTS •
[Solid 18ct white gold]
[Ready for lost-wax casting]
[Excellent fluidity and minimal shrinkage]
[Ethically sourced and lab certified]
[Consistent composition and melt quality]
• MORE INFO •
This casting grain consists of a 75% gold content alloyed with silver, copper, and other metals (nickel-free), resulting in the standard 18ct white gold formula that balances workability, strength, and a bright, lustrous shine. The grain is free from contaminants and refined to promote optimal melt behaviour. It is especially suitable for batch production, artisanal workshops, and custom fabrication processes. The uniform size and shape of the granules help achieve an even, controlled melt and reduce oxidation.
• METAL SPECIFICATIONS •
[18ct White Gold]
[Purity: 75%]
[Density: 16.10g/cc]
[Melting Range: 1075c - 1125c]

Green and Gold
Sustainable precious metals are revolutionizing the fine jewellery industry, offering an eco-friendly and ethical alternative that resonate with environmentally aware consumers seeking high-quality materials that align with their values.
Recycled precious metals are the perfect blend of beauty, durability, and sustainability. By incorporating recycled gold, silver, and platinum into production, manufacturers reduce the environmental impact typically associated with traditional mining practices. Using reclaimed metals not only helps preserve natural resources but also minimizes carbon emissions and energy consumption, ensuring that every piece of jewellery crafted contributes to a greener future.
This eco-conscious approach conserves natural resources, lowers carbon emissions and reduces energy usage, making every piece of jewellery a greener, more sustainable choice.

Authenticity Assured
To ensure the highest quality and authenticity, the metals used in our products undergo rigorous testing by an internationally accredited laboratory that specialize in precious metals.
Techniques like fire assay—a traditional method that provides highly accurate measurements of gold content—and XRF (X-ray fluorescence) analysis are used to test and certify the purity of each metal.
These advanced testing methods guarantee that every batch of material meets strict industry standards, ensuring the durability and beauty of your finished jewellery.
Each item dispatched from Ore Metals is documented with assay dates to offer transparency and peace of mind for consumers. This commitment to quality, combined with the sustainability of recycled metals, makes our precious metals the ideal choice for eco-friendly, ethically conscious jewellery making.
