Core Product Information
Carat Range: 1.0-1.25ct (1 carat series) and ~3.0ct (3 carat series, e.g., 3.02ct, 3.21ct).
Shape: Cushion cut, characterized by a rounded square outline with brilliant facets, offering a classic and elegant appearance.
Color Grade: Primarily DEF (near-colorless to colorless), ensuring high visual purity.
Clarity Grade: Includes VS1, VS2, VVS1, VVS2 (very slightly included to very, very slightly included), indicating minimal internal flaws.
Certification: All diamonds are IGI-certified, providing authoritative verification of quality (color, clarity, cut, and carat weight).
Production Methods: Available in both HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). HPHT replicates natural diamond formation conditions deep within the Earth, while CVD grows diamonds by layering carbon atoms in a controlled environment. Both methods produce diamonds with the same physical and chemical properties as natural diamonds.
Pricing & Availability
Price Range: $274.00 – $1,231.00 (varies by carat, color, clarity, and production method). Individual listings (e.g., 1.01ct HPHT) are priced at $293.00.

Product Features & Applications
Aesthetic Appeal: The cushion cut’s rounded corners and brilliant facets create a soft yet striking look, blending classic and modern styles.
Versatility: Suitable for various jewelry designs:
1 carat diamonds work well for understated pieces like solitaire engagement rings or delicate necklaces.
3 carat diamonds make bold statements in statement rings, pendant necklaces, or earrings.
Practicality: Lab-grown diamonds offer a sustainable alternative to natural diamonds, with consistent quality and traceable origins.

Tailored color grades or clarity levels.
