This ring is massive, and weighs 212 grs.; the hoop has been chased with foliage and flowers, and enamelled, and appears to have been much worn; a few traces of the enamel remain. The impress is the royal achievement, engraved on a piece of crystal or white sapphire, of oval form, measuring about three-quarters of an inch by five-eighths. The royal cognizance or the crest, on a helmet of mantlings, and ensigned with a crown, is a lion sejant affronté gu. crowned, holding in his dexter paw a naked sword, and in the sinister a sceptre, both erect and ppr. Above the crest appear the motto and the initials previously alluded to. The shield is surrounded by the collar of the Thistle, with the badge, and supported by unicorns chained and ducally gorged. On the dexter side there is a banner charged with the arms of Scotland; on the sinister another with three bars, over all a saltire. It is remarkable that the heraldic tinctures are represented on the back of the engraved stone, either by enamelling or painting, and the field or back-ground is coloured dark blue. This mode of ornamentation is found in some of the fine Italian works of the period. Sir Thomas Hepburn has a gold ring traditionally regarded as having been worn by Queen Mary of Scotland. The hoop is enamelled black; the setting consists of six opals surrounding one of much larger size, presenting the appearance of a six-petalled flower. Apropos of Queen Mary’s assumption of the arms of England in defiance of Elizabeth, they are so engraved upon a signet-ring that belonged to the late Earl of Buchan, as certified upon the little boxes containing facsimiles of the seal, and sold to all sight-seers at Holyrood Palace. The arms of England and France are placed in the first and fourth quarter of the shield: those of Scotland in the second quarter, and those of Ireland in the third quarter.
