Our Engravable Groovy Diamond Envelope Hinged Charm features our signature fluted radiating rays texture in 14k yellow gold, opening to reveal a sterling silver letter plate that can be engraved with a name, number, date, or tiny message. A bezel-set natural diamond adds a hint of brilliance. Styled solo or layered on a wheat chain, this mixed-metal design is part of our Love Notes capsule—Adina’s personal favorite.
