Crafted To Last

The Diamos Precious Metal Guide

At Diamos, we understand that a masterpiece requires more than just an exceptional diamond. The foundation of every creation is the precious metal that holds it. We make our rings, earrings, necklaces, pendants and bracelets and all our other jewellery using only the finest gold, meticulously blended to balance breathtaking beauty with enduring strength. At Diamos, every design is available in three timeless colors, including Yellow Gold, White Gold, and Rose Gold, and can be masterfully cast in your choice of 18 Karat, 14 Karat, or 9 Karat purity.

The Architecture of Gold

The purity of gold is universally measured in karats (K). Pure gold is 24K, meaning it is 99.9 percent pure. While breathtaking in its raw form, pure 24K gold is inherently soft and entirely unsuitable for the demands of daily wear. To create fine jewelry that is durable enough for everyday life while retaining a luxurious finish, pure gold is masterfully alloyed with strengthening metals such as silver, copper, and palladium. These precise alloys dictate the metal's strength, its resistance to scratches, and its final beautiful color.

Formulated with exactly 37.5 percent pure gold and 62.5 percent premium strengthening alloys, 9 Karat gold is engineered for absolute maximum resilience. This high concentration of fortifying metals creates the hardest and most structurally robust option in our collection. It is specifically designed to withstand the intense demands of rigorous daily wear, offering unparalleled resistance against scratching, bending, and blunt impact. Despite its formidable durability, 9 Karat gold polishes to a beautiful, radiant finish and provides an exceptionally rigid setting that secures your diamonds with absolute precision. It stands as the definitive choice for everyday fashion pieces, robust wedding bands, curated gifting collections, and highly active wearers who require their jewelry to remain completely unyielding through every aspect of life.
14K Gold

Comprising exactly 58.5 percent pure gold and 41.5 percent strengthening alloys, 14 Karat gold represents the ultimate convergence of structural resilience and timeless elegance. This precise formulation engineers a metal that is significantly harder and more rigid than higher karats, granting it extraordinary resistance to scratching, bending, and the natural impact of daily life. Because of its exceptional durability, 14 Karat gold creates a profoundly secure foundation for intricate settings, ensuring your diamonds remain perfectly anchored over a lifetime of continuous wear. Visually, this precise blend delivers a beautiful, classic gold radiance that brilliantly illuminates the fire of our elite diamonds. It remains our most highly recommended purity for engagement rings, wedding bands, and foundational everyday pieces. For clients who lead a dynamic, active lifestyle but demand a premium aesthetic, 14 Karat gold offers the definitive balance of practical longevity and effortless luxury.
18K Gold

Pure Gold 0%
Premium Alloys 0%
Composed of exactly 75 percent pure gold and 25 percent strengthening metals, 18 Karat gold is the historic benchmark for luxury jewelry. This exceptional level of purity yields a noticeably heavier weight and a vibrant, deeply saturated color. Because it contains a minimal amount of alloy, 18 Karat gold is highly resistant to tarnishing and naturally hypoallergenic, making it the ideal foundation for sensitive skin. While perfectly secure for setting our elite lab grown diamonds, its elevated pure gold content makes the metal slightly more malleable. It remains the definitive choice for legacy engagement rings, bespoke creations, and monumental heirloom pieces.

Every Shade of Diamos Gold

Every Diamos design is available in a selection of timeless metal colors, allowing you to personalize your jewelry to match your exact aesthetic without ever compromising on craftsmanship.

Yellow Gold

Defining traditional luxury, yellow gold delivers a warm, rich glow — made by alloying pure gold with precise proportions of silver and copper. Paired with our colorless D-F diamonds, it creates striking contrast; paired with vivid yellow diamonds, it deepens their radiant saturation.

  • Timeless Aesthetics
  • Vintage-Inspired
  • Everyday Luxury

White Gold

Modern elegance in a crisp, mirror-bright finish — pure gold fused with palladium and silver, finished in reflective rhodium. The setting seems to melt into colorless D-F diamonds for a seamless brilliant look, while amplifying fancy vivid yellow, blue and pink diamonds.

  • Contemporary Engagement
  • Halo Settings
  • Minimalist Designs

Rose Gold

Captivating and romantic, with a soft blush warmth from a higher concentration of copper — a tone that flatters every skin tone. It elevates the icy brilliance of colorless D-F diamonds with unexpected warmth, and amplifies the romantic saturation of fancy pink diamonds.
