Introduction to Cultured Pink Diamonds​

Cultivation Methods​

Cultured pink diamonds are crafted via High – Pressure High – Temperature (HPHT) or Chemical Vapor Deposition (CVD) techniques. In HPHT, carbon sources endure around 1500°C and 5 – 7 GPa pressure. Trace elements like nitrogen, along with specific lattice defects, are introduced during growth to yield the pink color. With CVD, carbon – bearing gases decompose in a vacuum. Precise control of growth factors and addition of suitable impurities lead to the formation of pink – hued diamonds on substrates.​

Color Grading​

Colors vary from Faint Pink, barely perceptible, to Very Light Pink, Light Pink, Fancy Light Pink (a bit more vivid), Fancy Pink (moderately saturated), Fancy Intense Pink (bright and highly saturated), Fancy Deep Pink (deep and rich), and the rare Fancy Vivid Pink, the most saturated and precious.​

Advantages​

These diamonds are a more affordable alternative to their scarce natural counterparts. Their production is environmentally friendly as it reduces the need for large – scale mining. Quality control in the lab guarantees consistent, high – grade stones with fewer inclusions.​

Application Scenarios​

Popular in jewelry such as rings, necklaces, and bracelets, adding a touch of romance and elegance. They also appeal to collectors, especially high – grade ones, which may appreciate in value.
