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.

How to Care for Your Ring
Fine jewelry deserves thoughtful care. These guidelines will keep your ring luminous for decades.
Daily Care
- Remove your ring before swimming, showering, or using cleaning products
- Apply lotion, perfume, and hairspray before putting on your ring
- Avoid wearing rings during gym workouts, gardening, or heavy-handed activities
Cleaning at Home
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.
Storage
Store rings individually in soft pouches or a compartmentalized jewelry box to prevent scratching.
Professional Care
Have your ring professionally cleaned and inspected once a year to check prong integrity and stone security.

How do I choose between brushed, polished and hammered cobalt bands?
Pick the finish by how much shine you want. Brushed bands look soft and matte, polished ones are mirror bright, and hammered bands have a dimpled texture. Many bands here combine brushed and polished areas, which gives contrast and a two-tone look without adding another metal.
What width of cobalt wedding band should I choose?
Widths here run from 4mm to 8mm. Slimmer bands of 4mm to 6mm look understated, while 7mm and 8mm bands feel bolder and show off details like grooves or inlays. Check the ring size chart, since wider bands can fit snugly.
What affects the price of cobalt wedding bands?
Width, finish and added details drive the price. Diamond or cubic zirconia accents, 14K gold accents, sterling silver or carbon fiber inlays, and IP plating in black or yellow all change the cost. Use the Price filter on this page to set a budget.
Which cobalt wedding band styles are most popular?
Beveled-edge and flat bands lead the list. Hammered, grooved domed, ridged and half-round styles follow close behind. Most are plain cobalt in brushed and polished finishes, with diamond-accent and gold-accent bands also appearing near the top.
