FM Konstglas / Ronneby Neodymium Lilac & Green Glass Fish

Description

A stunning Scandinavian green and lilac glass fish paperweight with large air bubble pattern. Made by FM Konstglas of Ronneby, Sweden, unmarked. Designed by Benito Marcolin, pattern number B850. Benito and his brother Josef founded FM Konstglas in 1961. The lilac layer is made from neodymium glass (also known as alexandrite glass), which changes colour according to different lighting conditions. It appears lilac in natural sunlight or yellow artificial light, and smoky blue in fluorescent/white light (see pictures). This is due to the presence of neodymium oxide (Nd²O³) in the glass.

Measures approx 4.5 inches tall by 7.5 inches in diameter at widest point.

Condition

Excellent condition, no chips or cracks, just a couple of small surface scratches, shown in final picture.
