What is a diamond?

Your Widget Header Text Goes Here Lorem ipsum dolor sit amet consectetur adipiscing elit. Alan Miller Jewelers Oregon, OH



Diamonds are crystals made up of carbon atoms arranged in a particular way. The arrangement of these atoms is what gives diamond its unique physical and optical properties. While graphite is also made up entirely of carbon atoms, it is soft enough to write with; whereas, diamond is so hard it can only be scratched by another diamond. Carbon atoms only arrange themselves into the unique structure needed to create diamonds under very specific conditions.

How diamonds form in nature

Your Widget Header Text Goes Here Lorem ipsum dolor sit amet consectetur adipiscing elit. Alan Miller Jewelers Oregon, OH

Diamonds are created approx. 100 miles beneath the earth's surface under immense heat and pressure

They then make their way to the surface over millions of years through volcanic activity

This process replicates the conditions that cause diamond formation in nature

Chemical Vapor Deposition  Alan Miller Jewelers Oregon, OHChemical Vapor Deposition  Alan Miller Jewelers Oregon, OH

Chemical Vapor Deposition

Hydro-carbon gas is superheated into plasma which releases carbon atoms that rain down onto a slice of diamond. These atoms attach to the existing crystal structure, and this causes the diamond to grow in vertical layers


These processes create different looking diamond rough

However, once cut and polished the result is a beautiful stone that is 100% a diamond
