Premium Asscher cut diamonds
THE RARE 1 DIFFERENCE
Premium Asscher Cut Diamonds by Rare 1
What began as a passion project has evolved into a distinguished pursuit: sourcing, refining, and presenting Asscher cut diamonds that embody precision, purity, and presence. At Rare 1, our work is informed by heritage and driven by innovation—each stone is an expression of intention as much as craftsmanship.
Why our Asschers stand apart
We prioritize optical clarity, proportional integrity, and the innate potential for the stepped facets that define the Asscher. Quality is never incidental; it is the criterion that guides every acquisition.
Beyond grade and geometry, we consider how each diamond will live—set, worn, and seen. Proportions and polish are tailored to complement bespoke settings and the personal aesthetics of our clients.
Whether you seek a statement solitaire, a central gem for an heirloom commission, or a meticulously matched pair, our Asscher collection is curated to inspire. We invite private viewings and consultations to align intentions, technical requirements, and aesthetic vision—ensuring every diamond we present is as deliberate as the life it will accompany.

Our Process
-
Bespoke Design
Together, we outline a thoughtful path forward that’s realistic, strategic, and precisely tailored to your specific needs. At Rare 1, custom jewelry design begins with a meaningful conversation. We listen closely — to your vision, your lifestyle, the milestones you celebrate, and the legacy you intend to create. From that firm foundation we craft a strategic plan that is both imaginative and pragmatic, ensuring every design decision reflects your priorities: beauty, durability, provenance, and enduring long-term value.
-
Strict Sourcing
Premium sourcing is the deliberate pursuit of the finest materials and extraordinary provenance, combining rigorous vetting, established relationships, and sustainable stewardship to secure gems and components that transcend ordinary value. It demands global market intelligence, direct partnerships with miners and cutters, and uncompromising standards of traceability and ethics—ensuring every stone or element is authenticated, responsibly sourced, and uniquely rare. For a private jeweler to the world's elite, premium sourcing is not only about scarcity or size, but about provenance, craftsmanship potential, and the story each piece brings to life, ultimately transforming raw rarity into heirloom distinction.
-
Collaborate & refine
Every project is different, and once your CAD designs are complete we’ll guide you through a streamlined approval process tailored to your preferences: you’ll receive detailed renders and interactive views for review, followed by a scheduled walkthrough—virtual or in person—where we’ll note any adjustments; after revisions are made we provide final confirmation files and a clear sign-off form so you can approve production with confidence, knowing every facet of the design reflects your vision.
