This is a great video showing the new Charles & Colvard hearts and arrows cut vs their standard cut in both color options, D/E/F color and G/H/I color, both in the new F1 crystal. The hearts and arrows is cut more to diamond proportions so it has a taller crown and a smaller table. Stone #1 is the new hearts and arrows cut F1 GHI color. Stone #2 is the standard cut F1 DEF color. Both cuts are available in either color. The GHI color face up very white while the DEF colors are completely colorless.
