Greek Key Wedding Band in Black IP-Plated Titanium, 6mm, Size 6.5–13
*This ring cannot be resized

Product Overview
The Greek Key pattern is one of the oldest continuous motifs in decorative art, a symbol of unity and the unbroken bond between two people. Rendered here in precise laser detail across a polished titanium band, it finds a thoroughly modern expression. The black IP finish deepens the contrast between the engraved lines and the surrounding metal, so the pattern reads clearly from across a room and holds its definition over time.
Titanium is the foundation that makes this ring work as a daily-wear piece. One of the most scratch-resistant metals used in jewelry, it is also remarkably lightweight and strong - comfortable for all-day wear whether you are at a desk, in a workshop, or anywhere in between. At 2.78 grams and 6mm wide, the band has real presence on the finger without any sense of bulk. The 2mm profile keeps the silhouette clean and low.

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.

Should I choose a titanium or 14K gold Greek key ring?
Choose gold for a classic look, titanium for a darker, modern one. This page offers 14K yellow gold rings, plus titanium bands including black IP-plated styles. Titanium suits a plain, matte or dark finish, while yellow gold gives a warm, polished shine.
What is the difference between cut-out and domed Greek key bands?
Cut-out bands show open spaces in the pattern; domed bands are rounded. A cut-out Greek key band looks lighter and more detailed, with the pattern pierced through the metal. A domed ring has a smooth, curved profile with the pattern across the top.
How do I find the right size for a wide Greek key band?
Measure your finger, then check the listed size range. Some titanium bands here are 6mm or 8mm wide, and wider bands can feel snugger than thin ones. Our Ring size chart helps you measure at home.
Are Greek key rings a good gift for men?
Yes, many styles here suit a man's hand well. The wider titanium bands, black IP-plated finishes and the antiqued sterling silver ring have a bold, masculine look. They also work as wedding bands or a gift for any wearer who likes a graphic pattern.
