William Goldberg Diamonds

What William Goldberg Diamonds does

William Goldberg Diamonds is a private, family-owned high jewelry company headquartered at 589 Fifth Avenue in New York and founded by Bill Goldberg in 1950. The company sells natural diamond jewelry and timepieces, including rings, men’s rings, necklaces, pendants, earrings, bracelets, fancy color diamond pieces, historic diamonds, and bridal jewelry. The indicated customer base includes affluent individual buyers, bridal customers, gift purchasers, selective retail partners, and luxury design collaborators.

Its core product differentiation rests on high jewelry craftsmanship, rare natural fancy colored diamonds, and the proprietary ASHOKA® diamond cut, described as a trademarked cushion shape with trimmed corners and a distinctive facet pattern. The business model appears to be one-time sales of high-value jewelry and ASHOKA® branded pieces through direct website inquiry or quote requests, supplemented by availability through exclusive retailers worldwide. Public pricing is not disclosed, which points to bespoke, consultation-based luxury pricing rather than standardized online checkout economics; no external funding or public revenue data is provided.
