Measure a ring you already own

  1. Pick a ring that fits the finger you're sizing.
  2. Measure the inside diameter in millimetres.
  3. Match the measurement to the chart below.

Tip: a millimetre ruler reads inside-edge to inside-edge across the ring.

Sizing tips

What if I'm between two sizes?

Round up. A ring that's slightly loose can be resized down; a ring that's too tight is harder to enlarge without affecting the setting.

When is the best time of day to measure?

Late afternoon or early evening. Fingers swell in heat and shrink in cold — measuring first thing in the morning or right after exercise will give you a misleading result.

Do wide bands fit differently?

Yes. Bands wider than 6 mm sit tighter than thin bands at the same nominal size. If you're choosing a wide band, go up a quarter to a half size.

Should I size for my knuckle or the base of my finger?

Whichever is larger — the ring needs to pass over the knuckle but should rest comfortably at the base. If your knuckle is much larger, talk to us about sizing beads.

Can my ring be resized later?

Most solitaires and standard bands can be resized within a few sizes. Eternity bands, tension settings, and patterned bands often cannot. When in doubt, ask before you buy.

Still unsure?

The 6ct Tennis Necklace is a lab grown diamond tennis necklace built around a continuous line of round brilliant diamonds, each set in its own four-prong basket so light moves freely from every angle. With 6 carats of total diamond weight resting just below the collarbone, it reads as a clean, classic riviera that works with everything from an open collar to an evening neckline. It suits anyone who wants one piece that carries real presence without leaning fussy.

Every necklace is made to order in solid gold, available in white, yellow, or rose to match the rest of your jewelry. The diamonds are real lab grown diamonds, IGI certified for cut, color, and clarity, and chemically identical to mined stones while typically costing 40-70% less. That difference is what lets you wear 6 carats every day rather than only on special occasions.

  • 6 carat total weight of round brilliant lab grown diamonds
  • Four-prong settings on a flexible, secure line
  • Solid 14k or 18k gold in white, yellow, or rose
  • IGI certified diamonds, made to order

Because it is made to order, give your build a little lead time. Your necklace ships free with insured delivery, carries a lifetime warranty against manufacturing defects, and is backed by our 30-day return policy.
