Jacob & Co. Unveils Angel Cut Diamond in Billionaire Double Tourbillon

Celebrating its 40th anniversary, Jacob & Co. introduces the Angel Cut, a patented diamond cut developed entirely in-house. Named after founder Jacob Arabo’s wife, Angela, it features 37 precisely engineered facets - reflecting their 37 years of marriage - merging technical innovation with personal symbolism. Designed to enhance light return while preserving elegance, the cut uses geometry rather than extra facets, with a lozenge-shaped table and stepped rectangular outline. The Angel Cut delivers a composed, continuous glow with controlled reflections, performing beautifully even in gem-set watch cases. It embodies precision, brilliance, and emotion, uniting high jewelry and watchmaking in a singular, luminous expression.
