How to Buy Jewellery for Your Partner Without Asking Their Size

The Surprise Dilemma

Nothing beats the magic of a surprise gift. But when that gift is a ring or a fitted bracelet, keeping it a secret while ensuring it fits perfectly can feel like a spy mission.

Here are the clever hacks our customers use to find their partner's jewellery sizes in secret.

Ring Size Hacks

• Borrow a Current Ring: Snitch a ring they already wear on their ring finger from their jewellery box. Trace the inside circle on a piece of paper, or press it into a bar of soap to create a physical template.
• The String Test: If they are a heavy sleeper, you can wrap a piece of thread around their ring finger while they sleep, marking the overlap point with a pen.
• Ask Their Best Friend: Partners often share their dream styles and sizes with friends. Ask their inner circle before buying.
• Default to Average: If you are totally unsure, the average female ring size is US 6 (India size 12). Buy a design that can be easily resized later. Read our resizing policy.

Necklace and Bracelet Sizes

Necklaces are much easier to buy without size checks. The standard female necklace length is 18 inches (45 cm), which sits gracefully below the collarbone on most women. For bracelets, the average length is 7 inches (18 cm).

Let's make sure the surprise lands perfectly.
