Rooted in over 200 years of heritage, EXELCO DIAMOND is a renowned cutter's brand that defined modern brilliance through the Ideal Round Brilliant Cut, created in 1919 by Marcel Tolkowsky. Across eight generations, this legacy has been refined by visionary masters, shaping the highest standards of diamond cutting.
Inspired by classical European art and culture, each ring embodies timeless aesthetics — where proportion, form, and light are harmonized into elegant design. More than jewelry, every creation reflects a philosophy of beauty cultivated through history.
From raw stone to radiant jewel, EXELCO DIAMOND pursues perfection in every detail. While honoring its heritage, the brand continues to evolve, crafting diamonds that shine with enduring brilliance — just like the life they are meant to accompany.
A true cutter's brand — from rough selection to the final facet.
The word "diamond" comes from the Greek adamas, meaning "eternal" and "unbreakable." Once cherished by kings and knights as a symbol of unwavering loyalty, it has become the ultimate expression of everlasting love.
At GINZA DIAMOND SHIRAISHI, this timeless philosophy endures. Each diamond is carefully selected by Japanese experts from the world's leading exchanges, evaluated beyond the 4Cs to ensure exceptional brilliance.
With over 18,000 meticulously curated stones, the brand embodies a pursuit of purity, strength, and enduring beauty — true to the original spirit of the diamond.
Inspired by the beauty and rhythms of nature.
Founded in Tokyo in 1967, Whitestone Gallery has long been a pioneering force in the Japanese art scene, dedicated to bringing outstanding Japanese artists into a global context while redefining the possibilities of the traditional art market. Expanding across Asia — from Karuizawa to Hong Kong and Taipei — the gallery continues to embrace cultural diversity and deepen dialogue between art and region.
In Seoul, this vision enters a new chapter within a building reimagined by Kengo Kuma & Associates. Overlooking Namsan Mountain Park, the structure becomes a contemporary cultural space where layered, multi-level galleries create a dynamic and immersive artistic experience.
Within this environment, NEW ART Group brings Whitestone Gallery Korea together with its jewelry maisons — where art transcends adornment and is woven into everyday life.
