  • 01. Crossfor Cut(Patent No.3181566)

    Crossfor Cut, invented in 1999, is a proprietary cutting technique that built our foundation. It is inspired by the shape of raw diamond stones and it was developed as a result of three years of repeated research and development. This precise cutting technique successfully creates mysterious, cross-shaped glitter in the center of a gemstone using the reflection of light.

  • 02. Dancing Stone(Patent No. 5424435)

    In 2010, Crossfor developed a gemstone setting technique that allows diamonds to sparkle by relying on slight movements of the human body. The technique was named "Dancing Stone" because the gemstone appears to be dancing. Dancing Stone, a registered product of Crossfor, moves the diamond finely, gently, and elegantly, and the technique opens up unlimited design potential.

  • 03. EXL-LOCK (Patent No.5424435)

    Clasps can be troublesome when putting on jewelry. As a solution, Crossfor developed the EXL-LOCK (pronounced "excellent lock"), which allows jewelry to be easily clipped on and off with one hand even when users are rushing to go out. EXL-LOCK, born from the passion to see more people enjoy jewelry, is technology that makes life easier for jewelry wearers.
