Labradorite is a variety of the most abundant mineral group on Earth, the feldspars. Its structure gives a beautiful play of colours, ranging from its natural grey to green, yellow or red as the stone is moved. Labradorite, moonstone and sunstone are all gem varieties of feldspar.
This ring forms part of a collection of 154 gems bequeathed to the V&A by the Reverend Chauncy Hare Townshend, a cleric and poet. Sir A. H. Church gave additional specimens in 1913. He also compiled the first catalogue Precious Stones: A Guide to the Townshend Collection. The first edition appeared in 1883. The stones are mounted as rings, although they may not have been intended to be worn.
