Mined vs Natural
We can help you identify whether diamonds are Lab Grown or Mined
Lab Grown
Same molecular structure and makeup of natural mined diamonds which are grown in a lab. This means the diamonds are grown in a controlled environment .
Mined Diamond
Natural or mined diamonds, are found in nature and mined from the earth. These diamonds take more time to grow and each is unique as they may have special inclusions and more varrying
The carat is the measure of weight of a diamond after it's been cut and shaped to it's final form. Diamonds are found in many sizes, the larger being more rare, the heavier the weight the more valuable the stone.
Carat
Diamonds are generally graded for their colour with the absence of colour being more valuable, from D to Z. If the diamond has a vivid colour then they are called coloured diamonds such as blue, pink, yellow and champagne.
Colour
Diamond are formed by stacking carbon particles and as it's formed there may be impurities or imperfections in the structure which are called inclusions. Diamonds free from inclusions or damage are more rare and grade from Flawless to Included.
Clarity
Based on the shape of the rough diamond, they are cut in a shape and specification that keeps the most weight while allowing the colour and clarity to be the highest grade. Therefore diamonds can be cut to varying degrees that give the most fire and appeal. The cut is graded from excellent to poor
Cut
The 4 C's
Shape, Dimension, Weight
Diamonds come in different shapes and sizes which are specified along with the 4 C's on a grading report. The diamond shapes may be round brilliant, princess cut, emerald cut, radiant, oval and other fancy shapes. They will have different dimensions and depending on the cut they will have varying weight. Some diamonds bay be thick and heavy or thin and light. No two diamonds are generally the same and that's what makes them special
