Precious Metals
14k Gold (Most Popular) — 58.3% pure gold. The ideal balance of durability and color richness. Available in yellow, white, and rose gold. The standard choice for fine jewelry and everyday wear.
18k Gold (Premium) — 75% pure gold. Richer color, preferred for heirloom and engagement pieces where purity and depth of tone matter most.
10k Gold (Everyday Value) — 41.7% pure gold. The most durable gold alloy. Ideal for active wearers. Stamped 417 inside the band.
Sterling Silver (925) — 92.5% pure silver. Cool-toned and elegant. Best for occasional wear; develops a warm natural patina over time.
Platinum — Naturally white, hypoallergenic, and exceptionally durable. The premium choice for those with nickel sensitivities or who want a ring built to last generations.
Alternative Metals
Stainless Steel — Extremely durable, scratch-resistant, and hypoallergenic. Maintains its polish with minimal maintenance. A popular choice for mens wedding bands and everyday rings. Does not tarnish or corrode.
Cobalt Chrome — Four times harder than platinum and naturally white. Cobalt chrome rings are virtually scratch-proof, lightweight, and permanently polished. An excellent alternative to white gold for those who want lasting brilliance without rhodium replating.
Titanium — Exceptionally lightweight and incredibly strong. About 45% lighter than steel, titanium is hypoallergenic and corrosion-resistant. A practical choice for active wearers who prefer a lighter ring without sacrificing durability.
Tungsten Carbide — One of the hardest materials used in jewelry. Tungsten rings are highly scratch-resistant and hold their polish indefinitely. Heavier than gold or titanium, which many wearers prefer for the substantial feel. Cannot be resized.
How to Find Your Ring Size
Finding your ring size is simple. Use one of these methods before purchasing.
Method 1: Measure an Existing Ring
Place a well-fitting ring on a ruler and measure the interior diameter in millimeters. Compare to our ring size chart.
Method 2: Measure Your Finger
Cut a thin strip of paper and wrap it snugly around the base of your finger. Mark where it overlaps, then measure in millimeters. Divide by 3.14 to get your diameter.

Mix a few drops of mild dish soap with warm water. Soak for 20-30 minutes, then gently scrub with a soft toothbrush. Rinse thoroughly and dry with a lint-free cloth. Safe for gold, platinum, and most gemstones. Avoid ultrasonic cleaners for pearls, opals, and emeralds.
