The posts of these earring (the part that goes into the ear) are stainless steel and the decorative metal is a rose gold-finished "pewter" (zinc based alloy). Because of the construction of these earrings, customization unfortunately is not possible.
Flower Enamel Gold Posts with Clear Glass Rivolvi Earrings
All of our earrings are safe from lead and nickel and safe for most ears, including sensitive. However if you have a metal allergy or if you would prefer a different style of earring (for example, a different metal, earring posts versus fishhook), or clasp (toggle versus lobsterclaw or even magnetic!) than as currently designed we do have other options.
Customizations are available, but please know that changes may increase cost and/or delay shipping.
