About us
OUR PERSPECTIVE
大阪 · 日本From Japan.
With intention.
Precision is a practice.
Beauty is a pursuit.
Based in Osaka, Apple Green Diamond Inc. introduced neon-green, HPHT-treated natural diamonds under the APPLE GREEN DIAMOND brand in 2001. DIAMONDLITE followed in 2009, with our recrystallized gemstone collections introduced in 2010.
Our work brings together a fascination with gemstones and the possibilities of technology. We invite you to look closer.

Beauty is only
the beginning.
A gemstone holds a world within it.
We see the possibility of another.
Through the art of recrystallization, selected gemstone material finds a new expression. A meeting of natural beauty, scientific curiosity and an exacting eye for colour.
