The Diamond Collection

Yes, 100% real. The Federal Trade Commission (FTC) in the United States and leading global gemological institutes like GIA and IGI officially classify lab-grown diamonds as genuine diamonds. They are not simulant stones like cubic zirconia or moissanite; they possess the exact same atomic structure, fire, scintillation, and lifelong durability as earth-mined diamonds.

Chemical Vapor Deposition (CVD) grows diamonds layer by layer from a hydrocarbon gas plasma inside a vacuum chamber onto diamond seed plates at moderate pressure, typically yielding Type IIa crystal purity. High Pressure High Temperature (HPHT) recreates deep earth conditions (approx. 1,500°C and 50,000 atmospheres) using hydraulic presses. Both techniques produce genuine, certified diamonds, and HIVA Diamond provides both CVD and HPHT inventories independently certified by IGI and GIA.

Every loose diamond in our vault—both lab-grown and natural—is independently graded by internationally accredited gemological laboratories, primarily IGI (International Gemological Institute) and GIA (Gemological Institute of America). Each diamond comes with a verifiable certificate detailing the 4Cs, optical specifications, proportions, and a microscopic laser inscription on the girdle matching the grading report.

Surat, Gujarat is the diamond capital of the world, responsible for cutting and polishing over 90% of all diamonds globally. By purchasing directly from HIVA Diamond, you acquire stones directly from the primary cutting atelier. This eliminates traditional middlemen markups, distributor margins, and luxury showroom overheads, delivering wholesale manufacturer pricing directly to discerning buyers.

Professional gemologists universally recommend prioritizing Cut above all else. A diamond's cut determines how effectively it captures and reflects light to produce brilliance, fire, and scintillation. An 'Excellent' or 'Ideal' cut stone will appear significantly brighter, whiter, and visually larger than a poorly cut diamond of higher nominal color or clarity.

An 'eye-clean' diamond has no inclusions or blemishes visible to the naked human eye from a standard viewing distance of 6 to 10 inches in normal daylight. Typically, clarity grades of VS1, VS2, and clean SI1 diamonds are eye-clean, offering the visual beauty of flawless diamonds at substantial price savings.

Elongated fancy shapes such as Oval, Marquise, Pear, and Emerald cuts have larger surface areas (spread) compared to round diamonds of identical carat weight. Their extended length-to-width ratios also create an elegant, flattering elongating effect on the wearer's hand.

Absolutely. As master lapidaries based in Surat, we cut over 28 distinct geometric shapes.
