At Glamira, diamonds have a special place in designs of jewelry and are selected according to some criterias. The first and most important step to choose a diamond is the compliance with ethical commitment that it must be 100% conflict-free to be used in Glamira products. Secondly, Glamira evaluates and classifies diamonds according to the 4Cs (colour, cut, clarity and carat) determined by GIA. The colour of a diamond refers to the combination of three components: hue, saturation and tone. The color-grading scale for diamonds ranges from D to Z.. A perfect diamond, known as D colour, has no colour at all. H colour is the most suitable colour grade according to both the best price-performance ratio and the best harmony with designs. That’s why at Glamira, diamonds in H colour are generally used.
