Diamond-Cut Box Chain Necklace in 14K White Gold, 2.4mm

Product Overview
Geometric square links meet diamond-cut facets in a chain that earns a second look. The rhodium finish gives it a bright, cool-white tone and tarnish resistance, while the solid gold construction underneath provides real weight and presence. Made in Italy to tight machine tolerances, every link is even and the finish is consistent from clasp to end.
Worn alone, it sits cleanly at the collarbone or lower depending on the length chosen. Paired with a pendant, the flat square links hold a bail without twisting. Two tones are not at play here, just one precise, polished surface that suits both dressed-up occasions and the kind of everyday wear that asks a chain to simply look good without any effort.

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 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.
All Sophia Jewelers lab-grown diamonds are conflict-free by definition and independently graded by IGI or GIA using the same 4C criteria applied to mined diamonds: cut, color, clarity, and carat weight.
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.
