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

Precious metals used in jewelry each possess unique properties affecting durability, appearance, and value. Understanding these characteristics helps you choose metals matching your lifestyle and preferences.
Platinum: Exceptionally durable, dense metal (95% purity in jewelry). Hypoallergenic, maintains polished appearance, most expensive precious metal.
Gold (14K): 58.3% pure gold alloyed with copper and other metals. Durable, warm appearance, widely available, moderately priced.
Gold (18K): 75% pure gold alloyed with copper and other metals. More pure than 14K, softer, warmer color, premium pricing.
Silver: 92.5% pure silver alloyed with copper (sterling). Beautiful appearance, softer than gold, requires regular polishing.
Purity standards ensure consumers understand exactly what they're purchasing. Proper hallmarking verifies metal content and provides confidence in jewelry authenticity.
Gold Karat Markings: 24K (pure), 22K, 18K, 14K, 10K. Higher karats contain more pure gold but are softer.
Platinum Markings: 950 (95% pure), 900, 850. Platinum pieces are typically marked with purity percentage rather than karatage.
Silver Markings: 925 (sterling), 900, 800. Sterling silver is the standard for fine jewelry and contains 92.5% pure silver.
Hallmark Significance: Hallmarks indicate metal type, purity, and maker. Professional hallmarking protects consumer interests and verifies quality.
Different metals exhibit varying durability and longevity characteristics. Understanding durability helps you select metals matching your activity level and daily wear requirements.
Platinum Durability: Exceptionally durable, resistant to scratching, maintains structural integrity for lifetime wear. Most durable precious metal.
Gold Durability: 14K and 18K gold are durable for daily wear. 14K is slightly harder than 18K due to alloy composition.
Silver Durability: Softer than gold, more prone to scratching and bending. Better for occasional wear or display pieces.
Repair & Maintenance: All precious metals can be repaired by skilled jewelers. Platinum is easiest to work with; silver repairs require most expertise.
Is platinum worth the extra cost?
