Grown Diamonds at 1/10th the price, But how?
What do I need to know?
Lab grown diamonds are 100% real as they have the same physical, chemical & optical structure as mined diamonds. They infact are impossible to detect even by a trained gemologist with their naked eye. The quality and authenticity is certified by reputed labs like IGI, GIA, SGL who certify mined diamonds.
Factors affecting the pricing
The Price of diamonds are determined by the 4Cs - Color, Cut, Clarity & Clarat.
In Natural diamonds, restricted supply by huge conglomerates controlling the supply chain made the diamond prices expensive. As the size of the diamond increases the price increases exponentially!
In Lab Grown diamonds, the advancement of technology has given the power to replicate natural diamond growing process to grow precise and pure diamonds of the highest quality in a matter of months.
The other factors in production like grading, cutting, polishing stay the same. Still, the overall cost of the diamonds comes down drastically because of the reduced raw material sourcing cost.
Price Comparison
On an average Lab grown diamonds are 60-95% less expensive than their mined counterparts of the same size & quality. The bigger the diamond size the greater the price advantage.
