I used these Black Onyx chips to create a necklace with a round Black Onyx pendant. I mixed the chips with round, oval and rectangle Black Onyx beads. I also added 3mm sterling silver round beads as spacers to define the shapes. These chips are also smooth in texture, which makes them look great with other smooth gemstones. The color is versatile enough to add or mix with other gemstones. I created another necklace with colored glass chips and added the Black Onyx chips as a filler.
