Though the modern trillion cut diamond was developed recently, in the 1960s, the triangular cut diamond was first seen in the 18th century, pioneered by the Asscher brothers, known for their namesake square-shaped diamond cut. 

This is a rare example of true antique trillion-cut diamonds, set in platinum circa 1910-1920. Converted from an early Art Deco era stick pin, this beautiful charm is ready for a new life! It features gorgeous calibre cut sapphires. Complete with a large 14k gold jump ring, it is an elegant addition to any necklace!
