Ring Sizing Guide
Selecting the correct ring size is essential for both comfort and security. For the most accurate fit, we recommend visiting a local jeweler to have your finger professionally measured.
Keep the following in mind when determining your size:
- Finger size can fluctuate throughout the day due to temperature, hydration, and activity levels.
- Measure your finger at the end of the day when it is at its largest.
- Avoid measuring your finger when your hands are cold, as fingers tend to shrink in lower temperatures.
- Wider bands typically fit more snugly and may require a slightly larger size.
If you are purchasing a surprise gift or engagement ring, consider borrowing a ring your recipient already wears on the intended finger and having it measured by a jeweler.
As all Marilex Diamonds pieces are made to order, customers are responsible for confirming their ring size before placing an order.
Due to the custom nature of our jewelry, we are unable to accept returns or exchanges for incorrect sizing. If you are unsure of your size, we encourage you to contact us before placing your order.
