Lab Grown Colored Diamonds
Natural colored diamonds come from accidental geological changes. They are super rare, only about 0.1% of all natural diamonds. Lab grown fancy color diamonds are controllable to produce, widely available and much cheaper.
Two production methods: as-grown and post-treatment.
HPHT fancy color diamonds usually get color while growing. We add trace elements to form yellow and blue stones directly. Most CVD colored diamonds start as colorless rough stones. Irradiation and heating create pink, green and red color diamonds. IGI and GIA reports state clearly if color is As-Grown or Treated.
Treated diamonds retain all original physical and chemical features. Colors hold well for everyday wear. Still, long high heat during welding or repair may cause fading occasionally.
Better Star provides HPHT and CVD colored lab diamonds. Our plant runs modern energy-saving machines and uses green power from Henan. We meet international rules on waste management and metal recycling, delivering ethical colored lab diamonds.
