Provenance
Acquired by the present owner from an antiquities dealer
Nicolo, from the Italian onicolo or “little onyx”, is a variety of layered onyx with a dark lower layer beneath a thin layer of pale bluish-white. Roman gem engravers learnt to exploit this structure, polishing the stone so that the pale layer formed a soft blue-grey surface, then cutting the design through it into the dark stone below. The result is a subtle, luminous image framed by a dark border, and nicolo became one of the most popular stones for Roman intaglios, particularly in the second and third centuries AD.
For a very similar ring, engraved with a grape vine, see Anna Beatriz Chadour, Rings: The Alice and Louis Koch Collection, Leeds, 1994, p. 88.
