Gem Fruit ‘Lab-Grown Diamond’. Bring the frameless ‘real sparkle’ to you.
https://www.creema-springs.jp/projects/labod-frameless

The ‘Gem Fruit’ series began with the playful idea of ‘harvesting cute gem fruits.’ This time, we have given form to the particularly sparkling ‘diamond fruit’ within that series. The ‘frameless’ design, with no prongs or setting, offers a special experience, as if wearing the diamond itself. Lab-grown diamonds share the same composition as natural diamonds and represent an environmentally friendly, sustainable choice. We deliver the ‘real sparkle’ to many people at a reasonable price while maintaining high quality.
1. Frameless Structure: Designed with a 1.1mm hole, allowing a chain to be threaded directly through.
2. Delicate and Elegant: A teardrop-shaped silhouette that naturally follows the neckline.
3. Reliable Quality Guarantee: Sparkle of F color and above, VS clarity and above.
4. Accessible Diamond: A luxurious single stone achievable from 19,800 yen.
Achieved 469% of the 100,000 yen funding goal shortly after launch. The initial sales batch sold out, and ‘re-stock (20,800 yen)’ is currently being accepted.
Many customers have given positive feedback.
