According to family tradition, these earrings were once part of the Shrewsbury Collection. Most recently, an antique diamond shamrock brooch, originally part of the Earl of Shrewsbury & Talbot's Jewellery Collection, appeared in the sale Noble Jewels, held by Sotheby's in Geneva on May 17, 2007, lot 336. 

John Talbot, 16th Earl Shrewsbury and Earl Waterford (1791-1852) married Maria Theresa, first daughter of William Talbot of Castle Talbot, Co. Wexford in 1814. Shrewsbury was a leading Catholic in England who built and endowed a number of churches and religious establishments and was a man of general charity. In 1841 he was commissioner for finding the best mode of promoting the Fine Arts in England; earlier he had built Alton Towers in Staffordshire, designed for him by Pugin.
