CU Synthetic Quartz

  CU refers to the culet, or small face on the pointed tip of a cut gemstone. Synthetic quartz has the advantage of an ideal culet compared to natural stones. While culets were historically cut large, modern preferences lean toward smaller or even non-existent culets to optimize light return. Synthetic quartz producers have perfected the ideal culet size to balance durability and appearance. A small culet prevents chipping yet minimizes light leakage. Skilled cutting aligns the culet precisely with the stone's axis for symmetry. The culet may be shaped into a point, kite, or keystone. Tiny culets on synthetic quartz maximize the cropped-corner rectangular cushion and other cuts. An optimized culet showcases the stone’s clarity and sparkle.
