Diamond rondels are an easy and elegant way to enhance your pearl necklace or bracelet. Rondels are designed for single strands of pearls only. Choosing the number of rondels to add to your pearls is a decision based on your style. Some people add rondels in between each pearl while others add one on each side of their pearl clasp. This 8mm rondel will fit with pearls sized 8mm-10mm depending on how you want the rondels to look in relation to the size of the pearls.
