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.

Necklace Length Guide

Chain length determines where a necklace sits on the body. Here is a quick reference:

• 14 inches (Choker): Sits at the base of the throat. Works with open necklines and off-shoulder styles.
• 16 inches (Princess): Rests at the collarbone. The most popular length for pendants and solitaire necklaces.
• 18 inches: Falls just below the collarbone. The most versatile all-purpose length — flatters most necklines and pendant sizes.
• 20 inches (Matinee): Sits at the top of the chest. Works well with higher necklines and larger pendants.
• 22-24 inches: Falls across the chest. Great for layering and statement looks.
• 28-30 inches (Opera): Dramatic length, sits below the neckline. Can be worn doubled for a different look.

When in doubt, 18 inches is the safe choice — it suits most necklines and pendant sizes.

Necklace Types at Sophia Jewelers

• Chain necklace — a continuous metal chain, the foundation of any jewelry wardrobe
• Pendant necklace — a chain with a single decorative element hanging from a bail
• Tennis necklace — a continuous line of diamonds or gemstones in a flexible setting
• Station necklace — a chain with evenly spaced stones or charms — elegant and understated
• Lariat / Y-necklace — a long chain that loops through itself, creating a Y shape
• Choker — a close-fitting necklace that sits at the throat, typically 14-16 inches

Clasp Types

• Lobster claw — the most secure clasp, standard for most fine necklaces
• Spring ring — lighter and slimmer, common on delicate chains
• Toggle — T-bar through a loop, decorative and easy to use one-handed
• Box clasp — clicks shut, used on heavier and multi-strand necklaces

The clasp type for each necklace is noted in the product description.

Layering Necklaces

Vary chain lengths by 2-4 inches between each layer. Mix chain widths and styles for texture. Combine a plain chain with a pendant necklace and a station necklace for a complete layered look. Two or three layers is the sweet spot — more than four tends to look busy.

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.
