The process of creating Costco Diamonds is called “laser ablation” and it involves heating the diamond to temperatures above 2,000 degrees Fahrenheit (1,093 degrees Celsius). The heat causes the carbon atoms in the diamond to explode and release electrons which are then captured by a laser.

The lasers used for this process are extremely powerful and can easily vaporize any other material within their range of operation. The heat that is generated by these lasers also causes nitrogen gas molecules within the diamond to combine with oxygen atoms in the air causing them to become superheated vapor. These vapors condense on the surfaces of the diamonds and form small cavities known as “voids” which trap all but one electron from each nitrogen molecule making them positively charged and capable of being attracted to a negatively charged surface such as a metal.

Are Costco Diamonds GIA Certified?

Costco diamonds are GIA certified, which means that the stones are graded and certified by the Gemological Institute of America. This is a respected independent organization that provides grading services for diamonds, precious metals, pearls and gemstones.

The GIA is one of the few organizations that has been able to offer this level of service at an affordable price. This makes them an attractive option for many people who want to buy diamonds but don’t have enough money for GIA certified diamonds.
