Heart Key Locket in Sterling Silver with Pavé Cubic Zirconia, 47mm Textured

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.

18k Gold (Premium)

75% pure gold. Richer in color, slightly softer than 14k. Preferred for heirloom and statement 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 wear 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. Created in a controlled environment, lab-grown diamonds are typically 50-70% less expensive than comparable mined stones. Lab-grown diamonds are conflict-free by origin. Grading reports are included only when the individual product details specify one.

Choosing the Right Pendant or Charm

Pendant Sizing and Chain Length

The chain length determines where a pendant sits on the body. A quick reference guide:

• 14 inches (Choker): Sits at the base of the throat. Works with small, delicate pendants only.
• 16 inches (Princess): Rests at the collarbone. The most popular length for solitaire and small pendants.
• 18 inches: Hangs just below the collarbone. Versatile — suits most pendant sizes and necklines.
• 20-22 inches (Matinee): Sits on the chest. Works well for larger, statement pendants.
• 24-30 inches (Opera): Falls below the neckline. Best for bold pendants or layered looks.

As a rule: larger and heavier pendants look best on longer chains. Small, delicate pendants can feel lost on a long chain.

Layering Pendants

Vary chain lengths by 2-4 inches between each layer. Classic three-layer: 16", 18", 20-22". Mix pendant sizes from small at the shortest layer to larger at the longest. Mixing chain styles — box chain, cable chain, snake chain — adds texture without clutter.

Charm Bracelet Compatibility

Charms are designed to attach via lobster claw clasp or jump ring to a bracelet or chain. Standard compatibility works with bracelets that accept 3-5mm wire gauges. Contact us with your bracelet details and we will confirm compatibility before you purchase.

• Locket — opens to hold a photo or keepsake; a timeless heirloom style

Caring for Your Jewelry

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

Daily Wear

• Remove jewelry before swimming, showering, or using cleaning products
• Apply lotion, perfume, and hairspray before putting on your jewelry
• Avoid wearing jewelry during gym workouts or high-contact activities
• Put jewelry on last when getting dressed

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. 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 laid 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.
