I made a colorful set with Swarovski elements. I used memory wire for the hoop earrings. The necklace reminds one of the Carrie Bradshaw (SATC) pieces. I used an eye pin for it and a ready made chain. It was pretty easy to make. The earrings took longer, memory wire is hard to work with. I had bought a discounted batch of Swarovski elements so it's not very pricey.
Make your own collar clips / cardigan clips accessories by up-cycling your old clip on earrings and a bracelet...
