Jewelry Size Guide: Rings, Necklaces & Bracelets

METHOD 01 / VISUAL DIAMETER

Measure an Existing Ring

Select a ring that fits the intended finger comfortably. Place it flat on a ruler and measure the inside edge to inside edge in millimeters (Inside Diameter).

METHOD 02 / CIRCUMFERENCE

Measure Finger with Paper Strip

Wrap a 1/2-inch wide paper strip around the base of your finger. Mark where the paper overlaps comfortably, then measure the length against a ruler in millimeters.

Master Jeweler Sizing Tips: 1. Fingers fluctuate in size throughout the day; measure at the end of the day when your hands are at their normal, warm size. 2. Ensure the measured size can slide smoothly over the widest part of your knuckle. 3. Wider ring bands (6mm+) fit tighter; we recommend choosing a 1/2 size larger for wide designs.

Finding Your Ideal Chain Length

The right chain length frames your face and accentuates your neckline. Consider your personal height, neck circumference, and the style of pendant you plan to wear.

14" Collar Fits snugly around the throat. Best for open-collar or scoop necks.
16" Choker Rests at the base of the neck, hitting right above the collarbone.
18" Princess Most Popular. Falls gracefully below the collarbone. Ideal for diamond solitaires.
20" Matinee Sits between the collarbone and the bust. Great for casual and business wear.
24" Opera Falls at or just below the bust line. Perfect for high necklines and statement pendants.
30" – 36" Rope Rests on the navel or can be doubled up into a two-strand choker.
WOMEN'S NECKLACE GUIDE

Standard Women's Lengths

For most women, an 18-inch chain is the gold standard for daily wear and solitaire diamond pendants. If you prefer a choker style, select 16 inches. For layering, pairing 16", 18", and 20" chains creates an elegant tiered waterfall.

MEN'S CHAIN GUIDE

Standard Men's Lengths

For men, the most common length is 20 inches, which sits right at the collarbone. A 22-inch chain falls a few inches below the collarbone, ideal for wearing with a cross, dog tag, or heavier pendant outside a shirt.

METHOD 01 / CHAIN & TENNIS BRACELETS

Measuring Wrist Circumference

Wrap a flexible measuring tape snugly around your wrist just below the wrist bone. Add 0.5 inches (1.2 cm) to your exact measurement for a comfortable, graceful drape.

METHOD 02 / SLIP-ON BANGLES

Measuring Hand for Bangles

Bring your thumb and little finger together as if putting on a bangle. Wrap measuring tape around the widest part of your hand (the knuckles). This ensures the bangle can slip over your hand.
