LABELLED FM Konstglas/Ronneby Neodymium Glass Penguin

Description

A stunning Scandinavian green and lilac glass penguin paperweight. Made by FM Konstglas of Ronneby, Sweden, unsigned, but still bears the original factory label. 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.

Size

Measures approx 9 inches tall by 3.5 inches in diameter at widest point.

Condition

Excellent condition, no chips or cracks, just a couple of small surface scratches.
