Natural Diamond

The Natural Diamond

Natural Diamonds are timeless. They were created over a billion years ago. They’re divided into Type I and type II based on their impurities. When grading a diamond for clarity, only those impurities noticeable by a trained eye under 10X magnification is considered.

Type Of Natural Diamond

1

Type Ia diamonds include nitrogen. Type Ia is the most plentiful. The nitrogen atoms are in clusters. Their color differs from near-colorless to light yellow.

2

Type IIb hasn’t any measurable nitrogen or boron particles. They’re mostly colorless but can also be light shades of brown. The famous “Hope Diamond” may be a Type IIb natural diamond.

Lab-grown Diamonds

Lab-grown Diamonds

Exhibit a similar physical, chemical, and visual properties as natural diamonds. Colorless lab-grown diamonds are Type II. Yellow lab-grown diamonds are Type Ib. Lab-Grown Diamonds aren’t imitations or simulate. they’re diamonds.

High-Pressure High-Temperature (HPHT)

HPHT is the method of growing diamonds using diamond presses. They mimic the acute conditions that form natural diamonds within Earth’s layer. Within the early stages of HPHT, the lab-diamonds were for industrial use. The method has improved since the technique was first utilized in 1955. HPHT diamonds are grown during a Cubo octahedral structure.

Chemical Vapor Deposition (CVD)

Starts with a natural diamond slice or seed during a chamber. Gas is injected within the chamber and mixed with high heat. The electrons separate and form plasma gas. The free carbon then collects on the seed, growing new diamond crystals. This method mostly creates brown or gray diamonds, that are then turned into colorless diamonds by an HPHT annealing process. CVD diamonds are produced during a tabular structure.
