The stone is a modified Asscher cut of 5.59cts and is valued at £95,000 to £120,000. It will be included in the Antique & Modern Jewellery sale on 3 July at Fellows & Sons in the Jewellery Quarter, Birmingham.
It was originally one part of a pair of earrings and could be remounted into a new piece of jewellery, most probably a ring.
Richard Slater, senior valuer at Fellows & Sons, said: “This is a truly beautiful diamond and the estimated value reflects its stunning design. It will be the highlight of the sale and no doubt generate a real buzz, also proving there is a market for such high value items outside London.”
The 3 July auction at Fellows also features an Art Deco diamond and emerald bracelet estimated at £15,000 to £20,000, with trap cut diamonds to the centre panel. The item is possibly from America.
The attention to detail is a clear indicator of quality, with a delightful combination of well matched bright green emeralds and lively diamonds. The superbly made bracelet mount also features some delicate engraving to the back of the clasp.

Notes to Editors:
The ‘Asscher cut’ was developed by the Amsterdam master cutter Isaac Joseph Asscher and first patented on 2 December 1902. The firm was founded in 1854 and spent its early years cutting Brazilian diamonds and was later to become one of the first De Beers sightholders following the discovery and subsequent mining of diamonds in South Africa around 1870. Indeed the firm was charged with the responsibility of cutting the 3,106ct Culinan rough diamond in 1905, the major facetted stones which now reside in the crown jewels.
The earliest form of modified square cut originally had a three-stepped crown and a seven-stepped base or pavilion with broad cut corners and a total of 74 facets including the table and culet. This cut was modified during the 1920s to only two or three crown steps and three or four pavilion steps, this modification resulting in more fire and brilliance than the original stones when cut to good proportions and unrivalled amongst square cut stones.
