What is the difference between a “Drill” and a “Crystal”

In order to reflect the light, each shape has multiple planes or facets facing in different directions. As the light hits these facets, they appear to sparkle as the light bounce back at you. The round and square drills are the same as what you find in your diamond painting kits. Square drills will have a combination of 9 or 13 facets to reflect the light and round drills contain 13 facets in a quilted checkerboard formation. Crystal drills (including “Metallics”) are faceted like a rhinestone or diamond.  There is an arrangement of 14 facets with a flat top. This tends to make crystal drills more reflective. Crystal drills can be made of a solid material or silver backed creating a transparent drill providing a beautiful depth and additional reflectivity and sparkle.
