River Stone DiamondsPrivate Consultation

The River Stone collection

A more discerning
standard for diamonds.

We personally review the details that matter: grade, proportions, media, growth method and availability, before a stone enters this collection.

A considered selection of CVD and HPHT lab-grown diamonds, including fancy colors, with final availability and order details confirmed before any order is finalized.

Search a certificate number from any diamond listing. We’ll open the matching River Stone page when it is currently available.

Explore our guides: loose IGI-certified diamonds · IGI certificate lookup · fancy-color diamonds · colored-diamond pricing.

Looking for several stones? Ask the Diamond Concierge for different shapes and carat weights in one request—for example, a 1.5 ct round, a 2 ct pear and a 3 ct emerald. Available matches appear together on one results page.

How RSD Selection worksWe begin with a curated shortlist. Every diamond shown passes our IGI, media, availability, growth-method and finish screens. Colorless stones stay within our stricter fluorescence screen; fancy-color stones retain the fluorescence grade reported on the certificate, including when it is not reported. RSD Selection places the strongest screened profiles first; it is a considered starting point—not a claim that one diamond is universally best.
