Riyanika Jewels Size Guide
Precision first. Use this guide to determine accurate sizes for rings, bangles/bracelets, and necklaces. All recommendations align to luxury-fit standards for 18K gold jewelry.
Ring Size
Method A — Measure an Existing Ring
- Place a ring that fits the intended finger on a millimetre ruler.
- Measure the inner diameter in mm (do not include metal thickness).
- Match to the quick reference below. Average 2–3 readings.
Method B — Measure Your Finger
- Wrap a narrow paper strip or thread around the base of the finger—snug, not tight.
- Mark the overlap. Measure the length in mm = circumference.
- Match to the quick reference below.
Professional Tips
- Measure at day’s end; hands are smaller in the morning and in cold conditions.
- If between sizes, select the larger.
- For wide bands (≥4 mm), size up by ¼–½.
- For full eternity rings, order exact size; these cannot be resized.
- Toi et Moi and multi-stone designs: match finger size and shank width for balance.
