Finding Your Perfect Fit
At Lume Store, we want your jewelry to feel like a natural extension of yourself. Ensuring the right fit is essential for both comfort and style. Use the guides below to find your perfect measurements for rings, necklaces, and bracelets.
1. Ring Sizing
Finding your ring size is easy with two simple methods. For the most accurate result, we recommend measuring your finger at the end of the day when it is at its largest.
How to Measure
-
The String Method: Wrap a piece of string or a thin strip of paper around the base of your finger. Mark the spot where the ends meet and measure the length in millimeters—this is your circumference.
-
The Existing Ring Method: Take a ring you already own that fits the intended finger perfectly. Measure the internal diameter (the distance across the middle) in millimeters.
Standard Size Chart
| Size (US) | Internal Diameter (mm) | Best For |
| 10 – 12 | 19.8 mm – 21.4 mm | Large / Statement fit |
| 13 – 15 | 22.2 mm – 23.8 mm | Extra Large / Thumb rings |
| 16 – 18 | 24.6 mm – 26.2 mm | Specialty sizing |
| 19 – 22 | 27.0 mm – 29.4 mm | Specialty oversized |
2. Necklace Lengths
Our collections, from the celestial Nebula to the rhythmic Mare, are designed to sit beautifully at various lengths.
-
35–40 cm (Choker/Short): Sits high on the neck, perfect for layering or open-collared shirts.
-
45 cm (Princess): The most common length; sits just below the throat on the collarbone.
-
50–55 cm (Matinee): Falls slightly lower, ideal for pendants and creating a focal point over clothing.
-
60 cm+ (Opera): A dramatic length that hangs over the chest, inspired by the depth of the ocean.
3. Bracelet Sizing
To find your bracelet size, measure your wrist just below the wrist bone using a flexible measuring tape.
-
For a snug fit: Add 1 cm to your wrist measurement.
-
For a comfort fit: Add 2 cm to your wrist measurement.
-
For a loose fit: Add 3 cm to your wrist measurement.
Tips for Gifting
Pro Tip: If you are buying a gift and don't know the size, the Size 54 is our most popular ring size for women, and a 45 cm necklace is the standard "one size fits most" choice.
