Measure a ring that fits.

Choose a ring worn on the intended finger and hand.
Measure its inside diameter through the centre, in millimetres.
Send the measurement and a clear photo beside a ruler to AUTIUM.

Wide bands and stacked rings may fit differently. If you have no suitable ring, arrange a fitting. Do not use screen circles as a calibrated measuring tool.

Before production: we confirm the exact HK size, gemstone, materials, total price and estimated timing in writing. Production begins after approval. If uncertain, contact us before payment.

Bangles & bracelets

Two different ways to fit.

A bracelet fits around the wrist. A rigid slip-on bangle must also pass over the hand; an opening or hinged bangle fits differently.

For a well-fitting bangle, provide its inner width and height in millimetres. For a round bangle, provide the inner diameter. For bracelets, send the wrist measurement and product code so we can confirm the appropriate allowance and finished length.

Do not assume every bracelet has an extension chain.

One complimentary bridal resize.

Singapore engagement and proposal-ring orders qualify for one complimentary resize of up to two HK sizes larger or smaller, where the design permits. Request it within 30 calendar days of receiving or collecting the ring.

We inspect the ring and confirm technical suitability before proceeding. Other rings, larger adjustments, subsequent adjustments and later requests are assessed individually and may incur charges confirmed before work begins.

Delivery, collection and insurance services are not included. Defects or departure from agreed specifications are assessed separately. Existing orders retain the terms promised when purchased. Applicable consumer rights remain unaffected.
