Voluminous, asymmetrical earrings are made of solid beech wood with gold leaf gilding. You could see a similar technique on the domes of churches, the Palace bas-reliefs or the paintings of Klimt. The hardware is brass gold plated.
How to keep
Wood is a living material, and requires careful handling. However, with proper handling, wood products will last you for decades. Probably, in this course of events, you will need to update the accessories, which is easy and inexpensive, but the wooden heart of the decoration will be preserved very well. My main recommendation is to store in conditions of natural humidity, i.e. not on the windowsill above the battery, not in the bathroom. A frequent question: what will happen if you get caught in the rain?? Nothing will happen:) The wood is treated with professional high-quality compositions (paints, impregnations, oils, lacquers-depends on the decorative tasks) and nothing will happen to it from the ingress of a small amount of water. Dry in natural conditions, again, not on the battery!) Swimming in wooden ornaments is still not worth it, although they will withstand a certain number of swims:)
