Lab Grown vs Mined Diamonds: An In-Depth Comparison

Lab grown diamonds, as the name suggests, are diamonds created in a laboratory. Using cutting-edge technology, such as High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD), scientists replicate the natural conditions under which diamonds form. The result is a diamond that is identical to a mined diamond in every way—chemically, physically, and visually.

In short: Lab-grown and mined diamonds: identical chemistry (pure crystallized carbon), identical Mohs 10 hardness, identical brilliance and fire under all lighting. Differences — origin (reactor vs deep-Earth), price (lab-grown 60-80% cheaper at identical 4Cs), environmental footprint (~10% the land impact, ~30% the water for lab-grown), resale value (lab-grown 20-30% of purchase vs 30-50% for natural).

What Are Mined Diamonds?

Mined diamonds are formed naturally over billions of years under the Earth’s surface. Through intense heat and pressure, carbon is transformed into diamond crystals, which are then extracted through mining operations. Mined diamonds have been valued for centuries, both for their rarity and the natural processes that shape them. For a range of available diamonds, check out our wholesale diamonds page.

The Visual and Physical Differences

When comparing lab grown diamonds to mined diamonds, there are no visible differences to the naked eye. Both sparkle with the same brilliance and possess the same durability. In fact, lab grown and mined diamonds are identical in terms of their chemical structure, hardness, and optical properties. Only specialised equipment can distinguish between the two, meaning that visually, one is just as beautiful as the other. Browse our collection of round lab grown diamonds to see for yourself.
