Precious Metals at Sophia Jewelers
Every piece is crafted from certified precious metals selected for lasting brilliance and skin-safe wear.
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. All Sophia Jewelers lab-grown diamonds are conflict-free by definition and independently graded by IGI or GIA.
Finding the Right Bracelet Size
Measure your wrist with a flexible tape measure or a strip of paper, wrapping snugly just below the wrist bone.
- Snug fit: wrist measurement + 0.5 inch
- Standard comfortable fit: wrist measurement + 0.75-1 inch
- Loose/stacked fit: wrist measurement + 1-1.5 inches
Most women's bracelets are sized 6.5 to 8 inches; 7 inches is the standard size. Men's bracelets typically range from 8 to 9 inches. The bracelet length is listed in each product description. Bangles do not adjust — measure the widest part of your hand (knuckle to knuckle) to find the right bangle diameter.
Bracelet Types at Sophia Jewelers
- Tennis bracelet — a continuous line of diamonds or gemstones in a flexible setting; the most classic fine bracelet style
- Bangle — a rigid circular bracelet that slips over the hand; worn singly or stacked in multiples
- Cuff — an open-ended bracelet that wraps around the wrist; adjustable and bold
- Charm bracelet — a link or chain bracelet designed to hold charms; grows with you over time
- Chain bracelet — interconnected metal links in cable, box, rope, or figaro patterns
- Link bracelet — wider, flat metal links; a classic choice in gold and silver
- Beaded bracelet — strung beads in gemstone, metal, or pearl; casual and stackable
Clasp Types
- Box clasp — clicks shut securely; standard for tennis and fine chain bracelets
- Lobster claw — the most secure clasp; easy to open one-handed
- Toggle — T-bar through a loop; decorative and easy to fasten
- Fold-over — folds flat against the bracelet; used on link and bangle styles
- Safety clasp — a secondary lock added to box clasps on high-value pieces
Stacking Bracelets
Mix textures and widths: pair a thin chain bracelet with a medium cuff and a bangle for depth. Odd numbers (3 or 5) tend to stack more naturally than even. Vary metal colors or keep to a single metal tone — both work. Delicate bracelets stack better on the same wrist; bolder pieces are best worn alone or with one accent piece.
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.

What affects the price of curb and Cuban chains?
Metal, width, and length set the price most. Solid 14K gold costs more than sterling silver, stainless steel, or titanium, and wider, longer chains use more material. Gold-plated and gold-filled options also differ from solid gold. Use the Price filter on this page to set a budget.
Which curb chain styles are most popular?
Titanium and sterling silver curb chains lead the list. Titanium curb necklaces in widths from 3.5mm to 10mm come first, followed by sterling silver chains in polished, beveled, and diamond-cut finishes. Slim 14K yellow gold curb chains and stainless steel necklaces with pendant-style fronts follow.
What width curb chain should I choose?
Pick 2mm to 4mm for subtle, 7mm and up for bold. Slim links sit quietly under a collar or hold a small pendant. Wider links, like the 7.5mm or 10mm chains here, are meant to stand alone as the main statement piece.
How do I pick the right chain length?
Choose 18 inches for a close fit, 20 to 24 for a relaxed drop. Many chains here come in a range, such as 18 to 24 inches. Shorter lengths sit near the collarbone, while 24 inches or more hangs on the chest. Shorter 7 to 9 inch sizes suit wrists.
Which metal is best for everyday curb chains?
Stainless steel, titanium, and solid gold suit daily wear well. They hold up to regular use, while plated pieces can wear over time. Sterling silver is a classic choice and may need occasional polishing. Compare yellow gold chains for a lasting warm tone.
What is the difference between a curb chain and a Cuban chain?
They are close relatives with flat, twisted, interlocking links. Cuban chains usually have tighter, thicker, more uniform links, while curb chains can be slimmer or finished in polished, beveled, or diamond-cut styles. If you want a different link look, try Figaro chains.
