Trilliant cut

Introduction and History of Trilliant Cut

  • The trilliant cut was introduced by the Asscher brothers in Amsterdam.
  • Leon Finker created his version of the triangular brilliant cut diamond, called the trillion cut.
  • Henry Meyer Diamond Company also cut triangular brilliant diamonds, but their stones were cut slightly differently.
  • Henry Meyer referred to his diamond cut as trilliant, while Finker called his cut trillion.
  • Marvin Finker, son of Leon Finker, patented the cut and trademarked the term Trillion.

Trademark Loss and Alternative Terms

  • In 1986, a federal court judge ruled that the words Trillion and Trilliant were phonetically equivalent.
  • The term trilliant, being a concatenation of the generic term triangular brilliant, could no longer be a registered trademark.
  • Finker introduced their patented cut as Trielle and TRIELLE in a stylized design.
  • After losing the trademark, the term trillion cut became used for all triangular-shaped gems.
  • GIA uses the terms triangular brilliant and triangular modified brilliant for non-branded diamonds.

Straight Cut Trilliant

  • The straight edged trillion cut is usually used as accent gemstones.
  • It displays sharp brilliance and fire when cut to the correct depth.
  • The ideal length to width ratio for this cut is 1:14.
  • Straight edged trillion cuts are commonly used on either side of a main, larger stone in a ring.

Curved Cut Trilliant

  • The curved triangular brilliant is known as trilliant.
  • This cut has three soft points and curved sides.
  • The length to width ratio should be 1:1 to keep the gemstone proportioned.
  • It is a softer version of the uncurved cut.
