Engagement Ring Resizing

Many rings and bands can be resized to fit within a few sizes. At Brilliantany, we provide complimentary resizing for engagement rings and wedding bands within 30 days of receipt.

It's generally feasible to adjust a ring up or down by a few sizes, but we recommend staying within a two-size difference for best results. Resizing beyond two sizes can present challenges. When selecting a ring size for yourself or a loved one, opting for a slightly larger size is often a wise choice.

Finding The Best Ring size

Planning a surprise proposal or ring gift? There are several discreet methods to determine ring size without giving away the surprise.

Consider asking your partner directly. Even if they suspect a proposal, surprising them with the ring style and center stone ensures the perfect fit.

To discreetly determine their ring size, borrow a ring they recently wore on their ring finger and visit a local jewelry repair shop. They can quickly and accurately measure the size for you. Just ensure the ring you use is typically worn on the ring finger.

Take a string and measure the inside diameter of a ring they wear on their ring finger. Or wrap it around their ring finger while they are sleeping. Measure the inside portion of the ring and compare it to the chart below. Once you have determined the millimeter diameter, compare it to the sizing chart below to find the right size

Engage a close friend or family member to discreetly gather their ring size information. Ensure they keep the surprise intact while they find out the size for you, allowing you to make the perfect purchase.

Utilize our printable sizing guide to easily determine the perfect size for your band or ring. For expert advice from our gemologists on finger sizing while maintaining the surprise, explore our resources.
