Guide
How to Choose Your Rings
Materials, sizing, engraving, center stones. Everything you need to know when choosing a LABONITO ring.
01Engagement Rings and Marriage Rings
An engagement ring is the ring you give at the proposal. The center stone diamond is its focal point. Marriage rings are what you both wear every day. LABONITO offers an engagement ring and a marriage ring for each of its 10 collections, so you can match them by name or choose them separately.
If you plan to stack your engagement ring and marriage ring together, choosing the same collection gives the most natural fit.
02Materials: Pt900 and K18
Every ring is available in Pt900 (platinum) and K18 (WG, PG, YG).
| Pt900 | K18 | |
|---|---|---|
| Color | White silver | WG (white) / PG (pink) / YG (yellow) |
| Character | Resistant to tarnishing, high purity. The bridal standard | Color options. Easy to match with your skin tone and other accessories |
| Price | Base price | Higher than Pt900 (approx. +¥50,000 depending on collection) |
If you are unsure, try them on at the shop and see which suits your hand.
03Sizing
Standard sizes are #3 to #20. Sizes #20.5 to #25.5 are also available (+¥11,000). After delivery, resizing is available within ±#2 (engraving must be redone with any resize).
Ring size changes with the season and time of day. At the shop, we measure for a size that fits comfortably even in the evening or when your fingers swell slightly.
04Center Stone (Engagement Ring)
The listed price for engagement rings is the setting-only price. Center stones accommodate 0.50ct to 1.20ct, and the setting price stays the same within this range (sizes outside this range are made to order).
For center stones, you can choose between lab-grown diamonds and natural diamonds. Lab-grown diamonds are real diamonds with the same composition, hardness, and brilliance as natural stones. With the same budget, you can choose a larger stone or a higher grade. For those who value the story of rarity, we also offer natural diamonds.
05Message Engraving
Choose from three fonts: Mincho, Script, and Gothic. First engraving is free. Character limits vary by design; most rings accommodate 10 characters for sizes up to #5 and 15 characters for #5 and above (VER and ATELIE engagement rings: 3/5 characters). Adding a secret stone reduces the limit by 2 characters.
Re-engraving after delivery costs ¥11,000.
06Secret Stone and Surface Finish
A hidden stone just for the two of you, set inside the ring. White, blue, or black diamond ¥5,500; birthstone ¥4,400 each (marriage rings also offer pink diamond at ¥18,700). * Blue diamond is treated.
| Month | Birthstone | Month | Birthstone |
|---|---|---|---|
| January | Garnet | July | Ruby |
| February | Amethyst | August | Peridot |
| March | Aquamarine | September | Sapphire |
| April | Diamond | October | Pink Tourmaline |
