14K Gold Filled Round Venetian Box Chain Necklace in 1.2mm Width, 16–20 Inch

A 1.2mm round Venetian box chain in 14K gold filled -- the Venetian box (or round box) chain is formed from square links rotated 45 degrees to create a rounded, uniform profile. It lays flat and smooth with a clean, modern look. Polished yellow gold, lobster clasp. Available in 16, 18, and 20 inch lengths.
Gold filled means 14/20 -- a thick layer of real 14K gold bonded to a base metal core. More durable than gold plated and will maintain its finish with proper care.

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.

How do I choose between a pearl strand and a solitaire pendant?
Choose a solitaire for everyday, a pearl strand for dressier looks. A round solitaire sits neatly at the collarbone and goes with almost anything. A pearl strand or an endless pearl necklace gives a softer, more polished finish and works well for dinners, events, or layering.
What affects the price of round necklaces?
Metal, stone type, and size drive the price most. Karat or metal (14K gold versus sterling silver), diamond or lab-grown diamond carat weight, pearl size, and chain width and length all play a part. Use the Price filter on this page to set a budget.
Which round necklace styles are most popular?
Round box chains and freshwater pearl necklaces lead the list. Gold filled and 14K yellow gold box chains appear at the top, followed by pearl strands, round solitaire necklaces, and diamond-cut cable chains. Cross necklaces also show up among the favorites.
What does a round box chain look like, and can I layer it?
A box chain is made of small square links that look smooth and even. Thinner widths, like 1mm to 1.5mm, layer well under a pendant or beside a pearl strand. Wider chains, like the 2.6mm and 3.6mm styles, work best on their own.
What length should I pick for a round necklace?
Sixteen to 18 inches suits most people at the collarbone. Shorter pearl lengths, like 12 or 14 inches, sit close to the neck. Longer chains, up to 36 inches, hang lower and layer easily. An 80 inch endless pearl necklace can be worn long or wrapped.
How do I care for pearl and chain necklaces?
Wipe them softly after wear and store each one separately. Pearls should be kept away from perfume and hairspray, and chains should be stored flat or hung to avoid tangles. See our jewelry care page for more detailed tips.
