One copper electroformed Real Copper Maple Seed post earrings. I remember loving these as a child, whirling to the ground like a helicopter. They may also be referred to as “whirlers,” “twisters”, whirly birds”, or “whirligigs,” samaras are the winged seeds produced by maple trees. Posts are made from surgical steel. Seed earrings measure approximately 20mm. The scientific and intricate process used to add layers of lovely copper is called electroforming. This process can be unpredictable and can take hours to days to complete just one wearable. There may be small perfect imperfections in the copper and it may darken over time. Each piece has been cleansed and sealed with you in mind.
