How to clean 18k solid gold jewellery

Regularly wiping your 18k gold with a soft, lint-free cloth can help remove oils and residue, preserving its natural gleam.
For a deeper clean, a solution of mild dish soap and warm water, combined with a gentle brushing using a soft-bristle brush, or by using Hagerty Jewel Clean can revitalise even the dullest pieces.

How to store 18k solid gold jewellery

Let us help you find the perfect fit! Remember to measure the correct finger on the correct hand, as they'll vary in size. To ensure that the ring fits over your knuckle, we recommend measuring when your hands are warm, as cold weather can shrink your finger.

Measure an Existing Ring

1. Find a ring that fits the finger on which you'd like to wear your by charlotte ring.

2. Take a ruler or measuring tape and measure the inner diameter of the ring.

3. Take a note of the millimetres, not centimetres.

4. Use our size chart above to find your perfect size.

Use Our Ring Sizer

1. Push the end of the ring sizer through the buckle, pulling to form a ring shape large enough to easily slip onto your finger.

2. Adjust the width around your finger until you are comfortable and confident that it won't slip off. Note that the correct size should allow the ring sizer to move over the knuckle without too much effort.

3. Take a note of which number the arrow is pointing to.
