This is a 16k, 18k & 24k gold plated and Biwa pearl earring and necklace set. Contrary to what most people think, pearls are not all round and all white. These Biwa pearls for instance, are kinda rectangular and are shades of purple, blue and green. I made the earrings using 18k gold plated wavy circular posts. From them I added Biwa pearls. And for the necklace I used 18k gold plated chain with a 14k gold plated clasp. Next I put on a larger Biwa pearl pendant. This set is perfectly, imperfect. The connecting rings are 24k gold.
