Diamond Jewelry

The world's most beloved, pure and mysterious brilliance




万物最高の硬度を持ち、
そして比類なき輝きを放つ宝石・ダイヤモンド。

その名はギリシャ語の
『アダマス(Adamas)』=『征服しがたい』
に由来します。

鉛筆の芯で馴染みのあるグラファイトと同じ成分でありながら、地中深くでこんなにも強く美しく生まれ変わるだなんて、地球の神秘を感じられずにはいられません。

長い年月を経ても変わることのないその煌きは、永遠の愛の証としてブライダルジュエリーや、10周年のプレゼントとしても人気があり、いつの時代でも世界中の女性を魅了し続けています。
