There may still be time to meet deadlines for your orders placed at iiiterate shift, my Shapeways market.
I don't keep a lot of 3D printed jewelry in stock - and I usually order black or white (white so that I can apply my own color). But don't let my two-tone obsession prevent you from adding lightweight colorful jewelry to your collection or as a gift.
Shapeways offers a large selection of colors for you to choose from. Note: you will need to DIY the items a bit so you can wear them by attaching ear wires and/or a neck chain of your choice.
