2. Necklace Length Guide
- 35cm – 40cm (14"-16"): Choker style. Fits closely around the neck. Ideal for children or petite women.
- 45cm (18"): The "Princess" length. Sits at the collarbone. Our most popular size for women.
- 50cm – 55cm (20"-22"): Sits at the chest level. The standard "Daily Wear" length for men.
- 60cm (24"): A longer statement length that sits mid-chest.
3. How to Measure at Home
- The Ring Method: Take a ring that fits you well and measure the Inner Diameter (the straight line across the middle of the inside of the ring) in millimeters (mm).
- Match: Find that mm measurement in the table above to determine your US / UAE Size. This is the size you will select on the product page.
