The factory of Blanka Diamonds in Antwerp manufactures excellent cut brilliants from 0.5 to 5cts, also with Hearts and Arrows pattern.
 The hearts and arrows cut (H&A) creates a perfectly symmetrical round brilliant diamond with 58 painstakingly cut and aligned facets which endlessly magnify light within the diamond.
One of our clients says " Only a handful manufacturers are able to create true Hearts and Arrows diamonds. If you are offered a H&A diamond that is not cut in Antwerp, you have an 80% chance it is not a true Hearts and Arrows".
Under special illumination, viewed from above and bottom the H&A cut brilliant presents a perfectly symmetrical pattern resembling a circle of hearts and arrows.
H&A brilliants from Blanka Diamonds are certified by the HRD (Diamond High Council) and the Antwerp division of the CGL.
CGL stands for Central Gem Laboratory, with its head office in Tokyo.
Grading of the H&A-pattern is indicated by putting a stamp on the sorting memo,
with a drawing of either H&A or Hearts only.
In Antwerp, you receive this sorting memo with all H&A brilliants of Blanka Diamonds. The parcel paper indicates the color, clarity, proportions and H&A-stamp and also diameter and depth.
In Tokyo, you may exchange this sorting memo at the CGL into a full certificate.
