Finding the right fit is part of loving your piece. Here's how to measure accurately at home before you order.

RING SIZE

Method One — Measure an Existing Ring

Place a ring that fits the finger you intend to wear your new piece on flat against a ruler. Measure the internal diameter in millimetres, then match to the chart below.

Method Two — Measure Your Finger

Wrap a thin strip of paper firmly around the base of your finger. Mark where it meets and measure the length in millimetres — your circumference. Divide by 3.14 for diameter. Match to the chart.

Conversion chart:

• UK H  /  EU 47  /  US 4  —  14.9 mm
• UK J  /  EU 49  /  US 5  —  15.7 mm
• UK L  /  EU 51  /  US 6  —  16.5 mm
• UK N  /  EU 53  /  US 7  —  17.3 mm
• UK P  /  EU 56  /  US 8  —  18.1 mm
• UK R  /  EU 58  /  US 9  —  18.9 mm
• UK T  /  EU 61  /  US 10  —  19.8 mm

Tips: fingers are slightly larger in warm weather and at the end of the day. Measure in the evening for the most reliable result. If you're between sizes, size up. Many Classic Collection rings are adjustable — this is noted in each product description.

BRACELET SIZE

Measure around your wrist with a tape or strip of paper and add 1–1.5cm for comfort.

• Wrist under 13cm  —  14cm bracelet
• Wrist 13–15cm  —  16cm bracelet
• Wrist 15–17cm  —  18cm bracelet
• Wrist 17–19cm  —  20cm bracelet

NECKLACE LENGTHS

• 40cm / 16" — collar
