They are ethical and sustainable diamonds. They are produced with a technology that allows the creation of diamonds identical to mined ones (physically, chemically and optically) without resorting to mining. The only difference between mined diamonds and lab-grown diamonds lies in their origin. This option not only considerably reduces the impact on the environment, but also eliminates the risks traditionally associated to its extraction.

The criteria for assessing the quality of lab-grown diamonds are the same as those used to assess mined diamonds, since both share identical qualities. We refer to the so-called '4C': Color, Clarity, Cut and Carat.


It is one of the most important qualities of diamonds. The more colourless (transparent), the more valuable it is considered, for its beauty and scarcity. There is a scale that classifies diamonds according to their color, establishing the following grades:

D-F Colourless
G-J Near-colourless
K-M Faint yellow
N-R Very light yellow
S-Z Light yellow
All the diamonds we use at LA MUSA are of excellent quality. They rank at the top of this scale, with an F-G rating.
This criterion refers to the tiny natural imperfections that are present in diamonds, known as inclusions (a fracture, liquid, a cloud, etc.). For its assessment, the crown of the diamond is observed regarding the following classification:
IF Internally flawless
VV1 y VV2 Very very slight inclusions
VS1 y VS2 Very slight inclusions
SI1 y SI2 Slight inclusions
I1, I2, I3 Imperfect
*The aforementioned assessments are carried out by an expert who examines the diamonds with a 10x loupe, except for grades I1, I2 and I3 that can be seen with the naked eye.
The diamonds that LA MUSA uses in its creations are of VS quality.
  • CUT
Cut refers to how well a diamond's facets interact with light. Diamonds shine depending on their proportions symmetry and polish. There are numerous types of cuts: brilliant, princess, oval, pear, baguette, marquise, etc.
The cut that we use the most at LA MUSA is the brilliant cut, the best known. The brilliant cut is the one with which the best angles are obtained so that the diamond reaches maximum sparkle, as it allows more light to be reflected. It is round in shape, with 57 facets or sides (sometimes 58, when the vertex is truncated).
    It refers to the weight, measured in carats. The metric carat corresponds to 0.20 gr.
