round brilliant diamonds shapeThe round shape is the most famous diamond cut as it accounts for nearly half of all polished diamonds. This is one of the great cuts named for its strong light properties. The ultimate formula for Round Brilliant was developed by Marcel Tolkowsky in 1919: all 58 facets are symmetrically cut, allowing …
Replicating what's happening deep underground is difficult, time-consuming and expensive, but the end result is the same as what's been mined for centuries. There are easier ways to do this, but only the process we use, replicating nature to rearrange atoms to grow beautiful diamonds as unique as fingerprints. We do this because we care …
What is diamond cut? Excellent cut diamonds have a uniform and clear pattern of light and dark areas and provide the highest level of fire and brilliance, as nearly all incoming light is reflected through the table. Very good cut diamonds are very similar to very good cut diamonds. They provide extraordinary brilliance and fire …

Also known as a diamond type 2a diamond, a Type IIa is one of four diamond classifications. Around 1-2% of all diamonds are classified as Type IIa (or 2a). These gems are purely, or almost purely carbon, and are considered to be the purest and most valuable of all. Type IIa diamonds have zero or …
If you put lab-grown CVD, HPHT, and natural diamonds in front of everyone's eyes, they are equally crystal clear, full of fire, and look exactly the same. However, natural diamonds are formed over a billion years or more, while cultivated diamonds are formed in units of days. Natural diamonds are formed by forces deep within …
