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. Round drills contain 13-23 facets in a quilted checkerboard formation. Crystal drills can be faceted in the same manor or are faceted like a rhinestone or diamond in an arrangement of 14 facets with a flat top. Crystal drills can be made from a transparent material, either resin or glass, with a silvered back. This arrangement creates a beautiful depth to the drill and additional reflectivity and sparkle.
This item, DMC 415 Square Crystal Drills, is made from resin with a silver foil backing.
DMC Colors for Crystal Drills
Square Crystal Drills are sold by DMC number . What I find most interesting about the crystal drills is that you can use them to replace more than one color. A shade lighter or darker almost always work for the same drill because of the way they reflect light. You may also be able to change hue – tones that are a little more blue a little more yellow due to the prismatic effect. If you do not have an exact DMC match with crystal drills, think more along the lines of I am looking for a dark red or light pink to find a replacement. You can also try this wonderful tool on Cody Hoover’s website to find a substitiution.
