Trilogy Engagement Rings
Lab-grown diamonds have been successfully produced for decades by manufacturing the exact conditions under which mined diamonds are formed.
Everything from the look, feel, weight and chemical makeup to the sparkle and light refraction are exactly the same as an earth grown diamond. Lab-grown diamonds have matured not only to meet their mined counterpart in every way, but even surpass the quality of a mined diamond.
Mined diamonds are at the mercy of the elements over hundreds of years, therefore often have a yellow discolouration and heavy inclusions, which in turn results in low clarity and sparkle. Laboratory diamonds on the other hand, though the process of creating them is very complex, are more consistent in quality (colour, clarity, cut, carat) as the environmental factors that they are formed under are able to be contained, which results in less waste with over 90% of lab-grown diamonds going on to be set into engagement rings.
