Rough Diamond Full White Color D E F G Unpolished Lab Created Diamonds
What are hpht grown diamond?
HPHT, the full name is High Pressure High Temperature, that is, high temperature and high pressure.A rough HPHT lab-grown diamond is grown from a small diamond seed. The diamond seed is placed in an environment that contains carbon (the molecular component of diamonds) and a metallic liquid which will help the carbon to settle around the diamond seed.
Why choose lab grown diamonds for jewelry?
Lab-grown diamonds, sometimes referred to as lab-created diamonds or lab-made diamonds, are becoming increasingly sought after for engagement rings and fine jewelry because they are much more affordable than natural diamonds. And what's great about lab-grown diamonds is that they are physically, chemically, and optically identical to earth-grown diamonds, so no one will know that your diamond was lab-grown. The sole difference between lab-grown diamonds and earth-grown diamonds is their origin. Lab-grown diamonds are available in all popular cuts, like the round-cut, cushion-cut, and oval-cut. Round-cut lab-grown diamonds are our bestseller since this shape is the most sparkly and incredibly versatile.
