It has been nearly a century since Marcel Tolkowsky revolutionized diamond cutting with the original Ideal Cut Diamond. To this day, the Ideal Cut remains the benchmark for industry excellence, and the name Tolkowsky® is synonymous with unsurpassed excellence. For this diamond engagement ring, a stunning Tolkowsky® round diamond is complemented by an additional round diamond on either side. Channel-set diamonds on the 14K white gold band complete the look. This fine jewelry ring has a total diamond weight of 5/8 carat. Each Tolkowsky® diamond ring comes with a certificate of authenticity and independent certification of the center stone.
