Precious Metals at Sophia Jewelers

Our jewelry comes in a range of metals, from gold, platinum and sterling silver to stainless steel and titanium. Each product page lists its exact metal.

14k Gold (Most Popular)

58.3% pure gold. The ideal balance of durability and color richness. Available in yellow gold, white gold, and rose gold. The standard choice for fine jewelry and everyday wear.

18k Gold (Premium)

75% pure gold. Richer in color, slightly softer than 14k. Preferred for statement and heirloom pieces where purity matters most.

10k Gold (Everyday Value)

41.7% pure gold. The most durable gold alloy — ideal for active wearers. Stamped 417 on the piece.

Sterling Silver

92.5% pure silver, stamped 925. Cool-toned and versatile. Best for occasional wear; silver develops a natural patina over time.

Platinum

Naturally white, hypoallergenic, and the most durable precious metal. Recommended for those with nickel sensitivities.

Titanium & Stainless Steel

Lightweight, hypoallergenic, and virtually maintenance-free. Excellent for everyday jewelry and sensitive skin.

Lab-Grown Diamonds

Lab-grown diamonds are physically, chemically, and optically identical to mined diamonds. Same carbon crystal structure, same hardness (10 on the Mohs scale), same brilliance. The difference is origin and price: created in a controlled environment, lab-grown diamonds are typically 50-70% less expensive than comparable mined stones, meaning you get a larger, higher-quality diamond for your budget.

Lab-grown diamonds are conflict-free by origin and graded on the same 4Cs as mined diamonds: cut, color, clarity and carat weight. Grading reports are included only when the individual product details specify one.

How to Care for Your Jewelry

Fine jewelry deserves thoughtful care. These guidelines will keep your pieces looking luminous for years.

Daily Wear

  • Remove jewelry before swimming, showering, or using cleaning products
  • Apply lotion, perfume, and hairspray before putting on your jewelry — chemicals can dull metal and damage stones
  • Avoid wearing jewelry during gym workouts or high-contact activities
  • Put jewelry on last when getting dressed — last on, first off

Cleaning at Home

Mix a few drops of mild dish soap with warm water. Soak for 15-20 minutes, then gently scrub with a soft toothbrush. Rinse thoroughly and dry with a lint-free cloth. This method is safe for gold, platinum, and most gemstones. Avoid ultrasonic cleaners for pearls, opals, and emeralds.

Storage

Store each piece separately in a soft pouch or compartmentalized jewelry box to prevent scratching. Keep chains flat or hung to avoid tangling. Store silver in anti-tarnish pouches to slow oxidation.

Professional Care

Have precious stone jewelry professionally cleaned and inspected once a year to check prong integrity, stone security, and clasp function. Most jewelers offer this service free of charge.

Shipping

Standard shipping is free on US orders of $99 or more. Orders ship within 2–3 business days in insured packaging.

  • Standard: free on US orders of $99 or more; under $99, the USPS rate is shown at checkout
  • Faster delivery: USPS Priority Mail, UPS 2nd Day Air and UPS Next Day Air, priced at checkout
  • International: Canada, the UK, Germany, Australia and Japan, priced at checkout

A tracking number is emailed as soon as your order ships.

Returns and Exchanges

Return or exchange unworn items within 30 days of delivery, with their original tags and packaging. Request a return authorization (RMA) first; refunds carry a 10% restocking fee, waived for store credit. Engraved and personalized pieces can't be returned.

To start a return or exchange, email info@sophiajewelers.com with your order number, or see how returns work.

How do I choose between half round and comfort-fit platinum bands?

Half round feels classic; comfort-fit feels roomier and smoother. A half round band has a gently curved outside and inside. A comfort-fit band has a rounded inside edge that slides over the knuckle easily, which many wearers like for all-day wear, especially in wider widths.

What width of platinum wedding band should I pick?

Choose 2mm to 4mm for slim, 5mm to 6mm for medium, and 8mm for bold. Slimmer bands sit neatly beside an engagement ring, while wider ones make a stronger statement on their own. If you are unsure, check your ring size chart, since wider bands can fit snugly.

What affects the price of platinum wedding rings?

Width, diamond content, and finish drive the price most. Wider platinum bands use more metal, and diamond channel styles add cost by total carat weight and the number of stones. Use the Price filter on this page to set a budget.

Which platinum wedding ring styles are most popular?

Round diamond channel bands and half round bands lead the list. Featherweight half round bands and lightweight comfort-fit bands in a range of widths follow closely. Polished milgrain comfort-fit styles also appear near the top among the plain options.
