CVD vs HPHT Lab Diamonds - Which is Better?
Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT) are the two primary methods for creating lab-grown diamonds. CVD diamonds account for over 60% of India's production and are generally preferred for their purity and fewer inclusions.
Key Differences:
- • CVD: Better clarity, Type IIA diamonds, slower growth
- • HPHT: Faster production, sometimes metallic inclusions
- • Price: Virtually identical in retail market
- • Quality: Both produce gem-quality diamonds
