Howlite is a well-known stone recognized for its dye-able qualities. It is a soft, porous mineral that is usually enhanced with dyes and resins to create colorful beads. Most Howlite is mined in Canada and the USA, then processed and created into beads in East Asia.The faceted rectangle beads measure from 8mm long by 8mm wide to 15mm long by 11mm wide by about 5mm thick. The center-drilled holes are about .5mm to 1mm. The strand is approximately 6.5" inches long and there are approximately 16 beads on a strand.All photos have been taken indoors with daylight bulbs, but as always, computer and mobile screens display colors differently.
