I have searched high and low for more information on these square cut diamonds with hearts and arrows (hearts and cupids). Hope International Inc., has a sales office in New York so a dealer should be able to find something out. Here is a link along with some of the information that I found. I really like the rounded corners on these stones.

Kanenori Kagawa of Hope International said, “We are probably the biggest manufacturer of Hearts and Arrows.” Because precisely manufactured stones always exhibit the Hearts and Arrows pattern of reflected facets, such stones were once commonly called Hearts and Arrows in the Japanese trade. But when the company that discovered the effect named itself Heart and Arrow Co., Ltd., the trade was no longer free to use the name. The Central Gem Laboratory, a leading Japanese grading laboratory, named the pattern Hearts and Cupids instead. “If stones do not show Hearts and Arrows, we will return them to the factory and repolish them until they do,” said Kagawa. Today the company has 300 cutters in India and “hopes to double” its production within a year. “China will probably grow to be a huge market,” said Kagawa , who recently opened a Hope sales office in Hong Kong, in addition to his Antwerp and New York offices. “But China aside, we would be happy to cater to the greater Asian communities throughout Southeast Asia.”
In Hope’s New York sales office, stones are sold with AGS certificates. “Our stones get AGS 0 without fail,” said Nick Ishii, executive director in charge of the New York office. “I wish AGS would
provide pictures of the stones on the certificates as Japanese labs do. The pictures clearly show Hearts and Arrows images, which would be a great advantage for retailers to show to their customers.” The company’s biggest problem, said Ishii, is “not having enough goods, particularly in larger sizes.”
Like other manufacturers, Japanese diamond cutters find that securing rough is their toughest problem. Hope International has three rough buyers stationed in Antwerp. “Whenever we hear rough is available, we fly there, be it Africa or Siberia or Canada,” said Kagawa. “I flew to Konakri, Guinea, myself,” said Ueda of Gem International, “but Antwerp is the best place for me to buy.”
