Primula sinensis, deep glass earrings

Primula sinensis, photograph from Mendel's Principles of Heredity by W. Bateson, 1909. Because of its availability and variability of colour, primula sinensis was the subject of an early study on genetics, following the principles of Gregor Mendel, whose work had come to light in 1900. R.P.Gregory studied its heritable traits for 15 years at the Cambridge University Botanic Garden, before losing his life in the First World War.

The earring pendant trays measure 12mm diameter and 3.5mm deep, and are made from silver-plated brass. The glass cabochons are 10mm across and 6mm in depth, deeper than standard cabochons, creating an interesting and lively magnifying effect. 

All earrings have sterling silver hooks and come in a sturdy black card gift box.
