From Wednesday, September 2nd to Tuesday, September 15th, we will be holding a promotion for Spinelli Kilcollin a fine jewelry brand from California that was founded in 2010.


To coincide with this event, the "KOTA SG Noir" ring will be available exclusively Isetan Shinjuku Store, Men's Building starting September 2nd (Wednesday). The ring's name incorporates the meaning of "koda," a word used by the Native American Dakota and Sioux tribes, which means "companion."

Other new jewelry pieces featuring black diamonds include the "AMI" series, shaped like a heart, and the "OMBRE" ring, which boasts a beautiful gradient reminiscent of the phases of the moon.

For two days only, on September 5th (Sat) and 6th (Sun), we will also be accepting custom orders where you can create your own special ring with your preferred combination of elements.
