Itchy Heschel & Company — Premier Diamond & Precious Stones, New York
Exceptional natural diamonds, rare colored gemstones, and important jewelry — personally sourced for discerning private clients and the world's finest jewelers.
THE ART OF NATURAL RARITY
At Itchy Heschel & Company, every diamond and gemstone is selected for extraordinary beauty, rarity, and provenance. Isaac M. Heschel — GIA Graduate Gemologist with more than 45 years in diamond manufacturing — personally evaluates each stone before it enters the collection.
From D Flawless and Type IIa white diamonds to rare Kashmir sapphires, Burmese rubies, Colombian emeralds, and important fancy-color diamonds — including Vivid Yellow, Vivid Pink, and Vivid Blue — we specialise in nature's finest creations. Our inventory spans loose stones, matched pairs, complete layouts, and signed estate jewels.
Based in the New York Diamond District at 15 West 47th Street, Suite 708, we serve private collectors, family offices, and select members of the trade worldwide. Every acquisition is conducted with complete discretion and backed by decades of market expertise.
Only Natural. Only the Finest.
Unparalleled Jewelry Selection
Personally sourced natural diamonds and rare gemstones for collectors, investors, and discerning private clients worldwide. Every stone is hand-selected by Isaac M. Heschel, GIA Graduate Gemologist, from primary markets and private estates — never treated, never synthetic.
Extraordinary Fancy Shapes
Matching pairs. Perfectly matched layouts. One-of-a-kind creations. The extraordinary begins with the right stone. From exceptional rounds to distinctive fancy shapes, every D Flawless Type IIa diamond—among the rarest and most chemically pure diamonds in existence—is chosen for its remarkable cut, clarity, character, and brilliance.
Nature's Rarest Colors
Beyond exceptional white diamonds lies an extraordinary world of natural color. Vivid Yellow, Vivid Pink, Vivid Blue, and Vivid Orange diamonds. Kashmir sapphires, Burmese rubies, Colombian emeralds. No two are ever alike — and no treatments are ever accepted.
PERSONALIZED JEWELRY
Beyond our ready-to-wear selection, we offer fully customized services for crafting a unique piece that embodies your vision. Our team, led by Isaac Heschel, will listen closely to your preferences and guide you through every step of the design journey, ensuring the finished piece reflects your individual style and personality.
From selecting the ideal diamond — a radiant-cut D Flawless, a Type IIa oval, or a rare fancy-color stone — to choosing the metal, setting style, and finishing details, every bespoke commission is executed with the same uncompromising standards that have defined Itchy Heschel & Company for over four decades. Private appointments available at our New York Diamond District studio.
