Product Type: Rings

This is a signet ring for women that skips the family crest and goes straight to color: a cushion-shaped onyx, black or green, sitting in a smooth bezel on a band that broadens as it rises to meet the stone. The face is just under half an inch across, big enough to read from across a table and polished flat, so it looks like real jewelry rather than costume.

  • Half-inch onyx face. Desiregem cuts the stone 12 by 12 mm, about 0.47 inch on each side, with softly rounded corners.
  • Real weight. At about 5.6 grams (0.2 oz) it sits flat and solid, which is exactly why it should be sized snug: a heavy top on a loose shank spins.
  • Black or green. Black onyx reads graphic and sharp; green onyx is a clear, bright jewel tone that lifts denim, camel and white.
  • Sizes 7 to 10. Desiregem makes it in US ring sizes 7, 8, 9 and 10.

Choosing a Signet Ring for Women

A signet ring for women works when the face is generous and the band stays slim, which is exactly this shape. The shank is narrow at the back of the finger and widens toward the bezel, so the ring feels lighter than it looks while the onyx gets the attention. Desiregem lists the metal as 18K gold plated brass. The bezel is a continuous rim of metal with no prongs to catch on a sweater.

Onyx is the classic signet stone because it is opaque: a solid block of color instead of sparkle, with a glassy polish that turns the face into a small mirror when light strikes it at an angle.

How to Wear a Signet Ring

How to wear a signet ring used to be a rule: little finger, non-writing hand. Today it goes wherever it looks best. The index finger gives a statement face the most room, the middle finger is the next natural spot, and both usually take a larger size than the pinky. If you already wear a wedding band, put the signet on the other hand so the two never knock together. One bold face on a bare finger says more than three busy rings.

Measuring the Size of a Ring

The most reliable way to measure the size of a ring is to take one you already wear on the same finger and measure straight across the inside, edge to edge, then match the figure below. Paper strips and string stretch and slip, so treat them as a rough check, and measure in the evening when fingers are fullest.

Size chart, measured in inches
US size Inside diameter (in) Inside diameter (mm)
7 0.68 17.3
8 0.71 18.1
9 0.75 18.9
10 0.78 19.8

The shank widens under the stone, and a broad section sits tighter than a thin wire band of the same number. Landing halfway between two numbers? Go up one.

Onyx Signet Ring Care and Fit

Is onyx a good stone for a ring worn every day? Yes, with one habit. Onyx is a quartz-family stone that shrugs off everyday knocks, but grit in a pocket can leave fine hairlines on a polished face, so give the face a rub with a soft cloth and keep it apart from keys.

Black or green onyx, which goes with more? Black works with every color you own and is the easier evening choice. Green is the one that gets noticed, strongest against neutrals, navy and warm browns.

Where does the plating wear first? On the underside of the shank, where the ring rubs against the palm and other fingers. Plating is a thin layer over the brass, so take the ring off for showers, swimming and hand washing, let lotion and perfume dry before it goes back on, and store it on its own in a dry pouch.
