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.

US Ring Size Reference

  • Size 5 — 15.7mm
  • Size 6 — 16.5mm
  • Size 7 — 17.3mm
  • Size 8 — 18.2mm
  • Size 9 — 19.0mm
  • Size 10 — 19.8mm

For the full printable chart, visit our Ring Size Guide page. If you are between sizes, size up. Most rings can be resized 1-2 sizes by a local jeweler after purchase.

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 satin cobalt bands?

Brushed is understated, polished is bright, and satin sits softly between. Many bands here combine finishes, such as a brushed center with polished edges, for contrast. If you want a quiet everyday look, start with a brushed half-round band.

Which Chisel cobalt ring styles are most popular?

Beveled-edge, hammered, grooved domed and ridged bands lead the list. Half-round cobalt bands and styles with 14K gold accents follow close behind. Black IP-plated and sterling silver inlay bands also appear among the top sellers.

What do the black and yellow IP-plated cobalt bands look like?

IP plating gives the cobalt a black or yellow color. The black bands read dark and modern, while the yellow ones give a gold-toned look. Several come in center-groove, beveled or hammered profiles, mostly at 8mm wide.

How do I find my ring size for a wide band?

Measure with a ring sizer, and consider the band width. Wider bands like 8mm often feel snugger than narrow ones. Sizes here run 7 to 13, and our ring size chart can help you compare.
