Founded in 1976, we are manufacture of loose diamonds and jewelries in Japan. In 2001, we presented an original diamond cut shape named the O.E. cut. It was introduced by the Rapaport Diamond Report, TV programs and newspapers.
The O.E. cut diamond is derived from a formula totally different from Tolkowsky's ideal proportions. It brings stronger brilliancy, scintillation, and dispersion (fire) than the same 58 faceted excellent cut. We had patents at over 25 countries contain Japan, U.S and China. We have factories in Japan and China to product the O.E. cut diamonds and traditional shape diamonds.
We got awards from METI(Ministry of Economy, Trade & Industry) of Japan Government. This awards is for companies, which have high technology and excellent idea for business.
Our O.E. cut diamond jewelry named "Over Excellent" is selling at Mitsukoshi department store, Minamiaoyama shop, over twenty agent's shops in Japan and JAL/ANA's flight shops.
We sure that the O.E. cut diamond will bring you advantage on product differentiation strategy. In our company name, "Hohoemi" means smile and "Brains" means that we hope to success with partners (brains).
