Cultured freshwater pearls look amazing all on their own, and also pair fabulously with Swarovski or Preciosa Crystal beads. Standard strand length for pearls is 16 inches. String them on silk beading cord and always either knot in-between each pearl or use bead bumpers to protect them from scratching. Freshwater pearls are known for their small holes, so use a pearl reamer if you require a larger hole size. Always remove pearls from original strand. Freshwater pearls are a natural material and variations in size, shade, and shape are to be expected.
