They say a diamond is forever, and they would be correct. Diamonds are the hardest and oldest known material on earth. Only a diamond can cut another diamond. Diamonds in their natural state may come in an array of shapes, colors and sizes. They are formed by extremely intense pressure and heat, over 100 miles beneath the earth’s surface. Why are diamonds so expensive? It takes approximately 100 to 200 tons of earth to be mined for a single one carat rough diamond. Whether you plan on wearing a diamond, proposing to a loved one, or even as a solid investment; a diamond is forever.

On January 1, 2003, the Kimberley Process Certification Scheme for international trade in rough diamonds was implemented. Our rough diamonds come from conflict-free sources, and we abide by all UN guidelines and guarantee all our diamonds as conflict-free. By purchasing natural earth mined diamonds, you actually help support a 6 billion dollar a year industry - which employees millions of people worldwide (from miners to retailers and manufacturers alike).
