The best diamond jewelry brands are distinguished by exceptional quality, expert craftsmanship and innovative diamond cutting. This guide highlights six premier designers, each with their own specialized approach to jewelry making.
Six of the Best Diamond Jewelry Brands
Kwiat
With a family heritage spanning over a century, Kwiat is a master of the diamond-cutting art. They specialize in proprietary cuts like the ASHOKA and the Tiara Cut, which are engineered to maximize brilliance and face-up size, often appearing larger than other diamonds of the same carat weight. Kwiat’s designs focus on open settings that allow the maximum amount of light to enter the stone, ensuring every piece radiates with internal fire.
Rahaminov Diamonds
Based in Los Angeles, Rahaminov is a boutique powerhouse known for its diamond-first philosophy. They specialize in rare, large and uniquely shaped stones, most notably their signature Movál cut—a hybrid of an oval and a marquise. Because they often build the jewelry around a specific, one-of-a-kind diamond, Rahaminov pieces are perfect for those looking for jewelry that feels personal and unmatched.
Christopher Designs
Innovation is at the heart of Christopher Designs, the brand that revolutionized diamond faceting with the patented Crisscut technology. By adding more facets than a traditional stone, their specialized L’Amour Crisscut diamonds offer a significantly broader surface area and unmatched scintillation. This technical precision allows their diamonds to provide a much larger visual impact, making them a top choice for those who value modern engineering and maximum sparkle.
J.B. Star
J.B. Star designs and produces all of its jewelry in the United States, maintaining full control of the jewelry-making process from start to finish. The brand works predominantly in platinum, a demanding metal that is more difficult to craft and requires advanced expertise. J.B. Star also offers select styles in 18k gold and is known for using fancy-shaped side stones like trapezoids, half-moons and trillions to frame center diamonds.
Lab-Grown Diamond Jewelry Brands
Clarity Diamond
As a leader in the world of lab-grown diamonds, Clarity Diamond specializes in the Chemical Vapor Deposition (CVD) process to produce single-crystal diamonds of exceptional quality. Their focus is on high-carat weights and superior color and clarity grades that are virtually indistinguishable from their natural counterparts. All Clarity diamonds are graded by GIA, a rare distinction within the lab-grown market. For the tech-forward or eco-conscious individual, Clarity Diamond offers a modern, sustainable path to high-end luxury.
Bridal Diamond Jewelry Brands
A.Jaffe
Founded in 1892, A.Jaffe is one of the only brands that places as much emphasis on the feel of the ring as the beauty of the stone. They are famous for their signature quilted interior and squared-off shank, which are designed to prevent the ring from spinning and provide unparalleled comfort. Specializing in bridal jewelry that stands the test of time, A.Jaffe combines ethical sourcing with rigorous craftsmanship to create a lifetime piece.
Whether you are looking for a patented cut that maximizes light or a handcrafted setting with a rich history, these six brands offer the ultimate in performance and design.
