In addition to buying precious metals, we craft platinum wedding bands that are 95% pure. Use the guide below to understand the alloys and properties we rely on when fabricating new pieces or evaluating estate jewelry.

Platinum Group Metals

Six Platinum Group Metals (PGM’s): Platinum, Palladium, Ruthenium, Iridium, Rhodium, Osmium

How PGMs Are Used

  • Rhodium is used in plating solutions.
  • Osmium is used in the manufacture of expensive pen points.
  • Palladium, iridium and ruthenium are commonly alloyed with platinum.
  • Combining alloying elements creates purpose alloys to improve casting flow, color, or polish.
  • Only 5% alloy content can dramatically change platinum’s hardness and workability.

Common Platinum Alloys

  • 950 Pt / 50 Ru: Ideal for tubing and die-struck wedding rings; Vickers hardness 130 (210 when work-hardened). Melts 1795–1780 °C. Preferred by the Platinum Guild and used in our bands.
  • 950 Pt / 50 Co: Excellent for casting with Vickers hardness 135 (up to 270 work-hardened) and slight ferromagnetism. Melts 1770–1680 °C.
  • 950 Pt / 50 Ir: Softer castings (Vickers 80) but can be work-hardened; common in Germany and Japan for safety catches and pins.
  • 900 Pt / 100 Ir: American favorite for hand fabrication; melting range 1800–1780 °C with Vickers hardness 110.

Platinum Alloy Standards

U.S. regulations require at least 95% platinum and 5% PGMs to label a piece “platinum.” Alloys above 95% can be stamped “PLAT” while 75–95% items must include the secondary metal (e.g., IRIDPLAT). Common American alloys include 95/5 Pt/Ru, 95/5 Pt/Co, and 90/10 Pt/Ir.

General Platinum Information

Platinum has marked life’s celebrations since ancient Egypt and Louis XVI’s court. It remains prized for its strength, purity, rarity, luster, and fashion versatility.

  • Strength: Weighs 60% more than karat gold and resists material loss, making it ideal for daily wear.
  • Purity: Fine jewelry typically contains 90% or 95% platinum, is hypoallergenic, and resists tarnish.
  • Rarity: Ten tons of ore yield just one ounce of platinum, versus three tons for gold.
  • Luster: Neutral white sheen enhances diamond brilliance.
  • Style: Platinum pairs beautifully with 18k gold accents for modern designs.

Platinum Jewelry & Weddings

Designers favor platinum for its durable prongs and ability to secure legendary diamonds such as the Hope and Koh-i-Noor. Bridal couples choose it for lifelong protection of engagement rings and wedding bands.

Buying Platinum Jewelry

Modern platinum pieces often include 18k gold details. Look for markings like “IRIDPLAT” (90% Pt / 10% Ir) or “PLAT” (95% Pt). Its density and luster make platinum a wise long-term investment.
