THE HOLLOWAY DIFFERENCE All Holloway diamonds above 0.70ct are GIA certified. All diamonds we sell, including the small ones, in addition to a GIA cert also pass the HCA and Ideal-Scope test.
HCA – Determines the diamond cut quality, potential to sparkle and its size relative to an average diamond of the same carat weight.
Ideal-Scope – Determines diamond light leakage.
ASET – Determines fancy shape diamond light leakage.
