If you do not know your size, please use the measurement tool below.
You can check your approximate size simply by placing a ring you normally wear on your smartphone or tablet screen.
If you do not have a ring, you can also measure by the circumference of your finger.
The fit of a ring can vary depending on its design and width.
Wider rings (voluminous designs) have a larger surface area in contact with the finger, so they tend to feel tighter than thinner rings of the same size. Therefore, when choosing a wider design, we recommend selecting a size about one size larger than what you usually wear.
Ring size standards vary by country and region.
If you know your size in another country, please use the conversion chart below as a guide to check the size that fits you.

This is a double ring that combines two parts.
Combining a simple flat ring made of SV925 with a K10YG ring creates a three-dimensional ring .
It is designed so that the two parts do not come apart when worn.
To combine the two parts, insert the thinner end of the thin ring into the flat ring and slide it to secure it in place.
A double ring is worn on two fingers, and can be worn on any finger as long as the size fits.
The middle and ring fingers have a limited range of motion, so you can use it without feeling any restriction.
Both can be worn as rings on their own, but the thinner one will be slightly larger, so please refer to the size guide below.
Because flat rings are wide, they may feel smaller than their actual size, so we recommend choosing a slightly larger size.
Thin rings are worn on two fingers, so the sizes listed are not exact.
Also, the two rings are different sizes.
| size | Flat Ring | Thin Ring |
|---|---|---|
| S | Approximately No. 9 | Approx. 9 - 12 |
| M |
Approximately No. 11 | Approximately 1 1 - 14 size |
| L |
Approximately No. 13 | Approximately 13 - 16 size |
Example: I am wearing a size M on my middle finger (size 12) and ring finger (size 10.5).

We use materials that can be used for a long time - precious metals such as 925 silver, K10, and K18, and pearls, a gift from nature.
Precious metals are materials that have been passed down by human hands, repeatedly changing shape, and retain their value over time.
The form has been carefully designed to look beautiful from any angle. The minimalist design is alive with sensitive details.
This jewelry will appeal to anyone, regardless of style or gender, and will satisfy even the most detail-conscious person.
After use, gently wipe off sweat or dirt with a soft cloth. Store away from moisture and air to maintain its beautiful shine.
