• 18CT PURPLE GOLD CASTING GRAIN •
Our 18ct Purple Gold Casting Grain, also known as 750 Purple Gold, is a rare and luxurious alloy, perfect for creating unique and high-end jewellery pieces. Made from a precise combination of gold and aluminium, these casting grains showcase the striking deep purple hue that sets Purple Gold apart. Whether you’re casting bespoke jewellery designs or crafting exclusive components, our Purple Gold Casting Grain ensures quality, authenticity, and elegance in every creation. Its rich colour and rarity make it a must-have for any artisan or professional jeweller seeking to stand out.
Due to its unique alloy composition, traditional granulation techniques are not suitable for producing Purple Gold casting grain. As a result, the grains do not form the typical spherical shapes commonly associated with casting grain. Instead, they take on a more natural, nugget-like appearance, reminiscent of raw ore, and can feature a grey outer surface or patches caused by oxidation during the fabrication process.

Purple Gold, a mysterious, unique and luxurious metal alloy, has gained popularity for its striking hue and exclusive presence in high-end jewellery. But what exactly is Purple Gold? This intriguing alloy is created by combining gold with aluminium, to produce its distinctive purple colour. The creation process involves a precise balance of elements, ensuring the rich, deep purple shade that sets it apart. However, while Purple Gold's aesthetic appeal is undeniable, it's important to understand its properties, both beneficial and challenging. On the one hand, Purple Gold's rarity and unique colour make it a sought-after material for exclusive jewellery designs, offering a distinct alternative to traditional gold hues. On the other hand, the alloy's composition can lead to some limitations. Notably, Purple Gold can be more brittle than other gold alloys, requiring careful handling during jewellery making. Additionally, its porous nature requires meticulous crafting experience to preserve its stunning appearance. This blend of pros and cons highlights the need for skilled craftsmanship when working with Purple Gold, ensuring that its beauty is showcased while maintaining its integrity.
• METAL SPECIFICATIONS •
[18k Purple Gold]
[Purity: 75% Au, 25% Al]
[Density: 15.00g/cm³]
[Melting Range: 800–1065°C]
[Hardness HV (Vickers): 334]
[Hallmarked: N/a]
• USAGE & APPLICATIONS •
Ideal for lost-wax casting, custom jewellery design, and alloy blending. Whether you're casting rings, pendants, or intricate charms, this grain provides a clean and predictable result with strong mechanical properties and bright polish potential. Use in a controlled environment with proper flux and crucible to maximise finish quality and metal yield. Before embarking on a project with purple gold, it's essential to understand its distinct properties and limitations as a unique alloy:
-Due to its unique composition, purple gold naturally exhibits pitting and imperfections. These characteristics are inherent to the material and should be considered an integral part of its organic appeal.
It is advisable to steer clear of intricate filigree work or parts that will be subject to external mechanical stresses, as purple gold may not withstand these conditions well.
For enhanced durability and to preserve its aesthetic, incorporating a frame made of a more ductile alloy is recommended. This frame serves to support and safeguard the purple gold elements within the jewellery piece.

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.
