Description:
• 18CT PURPLE GOLD FLAT RECTANGLE CABOCHON •
The 18ct purple gold flat rectangle cabochon is a clean-cut, low-profile form designed for jewellery makers seeking precision and distinction. This refined, flat-bodied cabochon highlights the rich violet tone of solid 750 purple gold, offering a rare material option for minimal, geometric, or architectural pieces. Its slim silhouette enhances surface polish while minimizing weight, making it ideal for elegant designs that emphasise colour and form. Precision cut and ethically sourced, each piece invites elevated craftsmanship and thoughtful integration into bespoke jewellery.
• KEY POINTS •
[Solid 18ct purple gold]
[Striking purple hue]
[Polished finish]
[Ethically sourced & lab certified]
• MORE INFO •
Purple gold is an alloy known for its deep violet tone, achieved by carefully alloying gold with aluminium. Unlike traditional gold hues, this rare variation offers bold chromatic contrast and exclusivity in fine jewellery. The flat rectangle cabochon lends itself well to flush settings, modern lockets, minimalist signets, and high-end inlays. While its colour is striking, purple gold’s structure requires care — it is more brittle than other alloys and should be set into protective or framed environments. Surface pitting and minor inclusions are intrinsic to this alloy’s nature, contributing to its raw organic beauty.
• METAL SPECIFICATIONS •
[Material: 18k Purple Gold]
[Density: 15.00g/cm³]
[Melting Range: 800°C – 1065°C]
[Hardness HV (Vickers): 334]
[Annealing Temp: 600°C]
• USAGE & APPLICATIONS •
Best suited to experienced metalsmiths and designers, the flat rectangle cabochon works beautifully in pieces where precision and aesthetic impact are essential. Use it in low-profile rings, recessed pendants, or framed earrings where it is supported structurally. Avoid using purple gold in flexible or load-bearing structures. For ideal presentation and long-term wear, encasing it within a bezel or stabilizing alloy is recommended. Its unique hue will complement modern lines, geometric motifs, and clean visual compositions.

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.
