Product Overview
A contrast of finishes defines this cobalt wedding band: a satin-brushed center sits between polished surfaces, and ridged edges frame the whole with a clean, modern line. The result is a band that reads as both refined and substantial, with enough visual detail to stand on its own.
Cobalt brings a natural bright white color and exceptional hardness to the design, holding its finish through the demands of everyday wear without the need for plating. The band is engravable, so a personal message, a date, or a set of initials can be added inside the shank.

- Available in ring sizes 7 to 13, including half sizes

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.

Store rings individually in soft pouches or a compartmentalized jewelry box to prevent scratching.

Have your ring professionally cleaned and inspected once a year to check prong integrity and stone security.

Frequently Asked Questions
Everything you need to know about our rings, sizing, metals, and care.
The simplest method is to wrap a thin strip of paper snugly around the base of your finger, mark where it overlaps, and measure the length in millimeters. Divide that number by 3.14 to get your ring diameter, then compare to our ring size chart. Measure in the evening when fingers are at their largest. If you are between sizes, always size up.
Sophia Jewelers rings are crafted in 10k, 14k, and 18k yellow gold, white gold, and rose gold; sterling silver (925); and platinum. 14k gold is the most popular choice, offering the ideal balance of purity, durability, and color richness. Platinum is naturally white and hypoallergenic. Contact us if you need guidance choosing the right metal.
Our platinum and sterling silver rings are hypoallergenic and well-suited for sensitive skin. White gold rings contain a nickel alloy which can cause reactions in people with nickel sensitivities. If you have a known nickel allergy, we recommend yellow gold, rose gold, or platinum.
Karat measures the purity of gold. 10k gold is 41.7% pure — the most durable and affordable, ideal for active daily wear. 14k gold is 58.3% pure — the most popular choice for fine jewelry, offering beauty, durability, and value. 18k gold is 75% pure with the richest color, preferred for heirloom and engagement pieces. All rings are hallmarked with their karat weight.
Most rings can be resized by a local jeweler within 1–2 sizes. Rings with full eternity bands or channel-set stones around the entire shank have limited resize options. If you are between sizes, we recommend sizing up. Contact us within 30 days of purchase if you have sizing questions.
We offer a 30-day return and exchange policy on all rings in original, unworn condition with original packaging. Custom-engraved and resized rings are not eligible for return. Email info@sophiajewelers.com with your order number to begin the process. Free return shipping is provided for exchanges.
