The Corona™ diamond is a new square cut created by Yuval Harary Diamonds, the same team that introduced the Fourever Concept technique several years ago. The company holds the design patent and registered trademark for this diamond cut.
The Corona has 65 total facets, 40 on the pavilion and 25 on the crown. The stones are cut in the company’s house factory in Ramat Gan, Israel. The square-cut stones are cut deeper than rounds in order to ensure the kind of light output that distinguishes the stone from other cuts. Corona cuts are available between 0.05 and 2 carats, in colors D through J and in clarities IF through 11. The Corona is certified by the Israel Diamond Institute (IDI).
Diamond Source of Virginia does not sell the Corona shape of diamond.
