TAKEMOTO and Purple Heartwood
Purple Heart Wood is by now the only known wood species with true purple color (not purplish), though its color may vary from purple, purplish red to purplish blue, etc. due to the different degrees of oxidation. I am the first designer and craftsman in the world to make the entire eyewear frame with Purple Heart Wood from 2012 on (before then, only a few high-end brands used this wood partially). There are many inevitable problems with glass frames made of whole pieces of Purple Heart Wood. The wood has high hardness but is easily fractured, and the color is difficult to be controlled. However, with many years of experience, I am able to make delicate frames by using unique techniques. In order to make use of the oxidation process which causes the change in color, I also purchased the wood materials by years to ensure it becomes perfect purple. It is very difficult to make the arms, but as you can see, I have completed all the processes perfectly. When you receive a pair of Purple-Heart-Wood-framed glasses, don't worry if you think it is not purple enough. The color will slowly change in the future if there is plenty of sunshine, and the process will be very interesting.
