Necklace body can be printed in 1 part with color changes at 3.08 mm and 3.68mm.
Print out the jump ring and cut with a sharp knife, then gently add to the necklace bridge.
No need for supports.
Necklace body and jewel can also be printed out separately.
Try different top fill patterns like “Aligned Rectilinear” (my favorite for this necklace) or "Octagram Spiral"
