Leaves Earrings–Taking more than 7 hours from harvest to completion, each piece begins with a Real Leaf or Botanical that is made semi-transparent, by exposing the lacy vein structure through an intricate filigree process. A delicate layer of copper is then applied to each leaf to strengthen and preserve it. The leaves are then hand dipped in 18k gold, rose gold, sterling silver. Our jewelry has been designed by Still Life artisans and handcrafted with care to preserve the essence of nature. For jewelry: We use sterling silver or 18k gold fill ear wires and chains.
