Sphere Diamond is not merely a brand; it is a refined evolution. As the sister house to S.Diamond, we carry forward a lineage of excellence in Bangkok's high jewelry scene.

While S.Diamond remains the guardian of natural diamond investment, Sphere Diamond explores the infinite possibilities of Premium Lab-Grown Diamonds—curated for those who demand the same level of mastery, but through a modern lens.

Experience our craftsmanship at CentralWorld, 1st Floor (Jewelry Zone), where tradition and innovation exist in perfect harmony.

Minimalist Luxury.
Bold Intentions.

Our aesthetic is defined by "Editorial Minimalism"—clean, structural, and unapologetically bold. We design for the woman who travels, the woman who leads, and the love stories that defy the ordinary.
