The British and Irish Pearls are found in a large black Muscle.... They are peculiar to rapid and stony rivers; and are common in Wales, and in the North of England, and in Scotland, and some parts of Ireland. In this country they are called by the vulgar _Kregin Diliw_, i.e. Deluge shells; as if Nature had not intended the shells for the rivers; but being brought thither by the Universal Deluge, they had continued there, and so propagated their kind ever since. Those who fish here for Pearls, know partly by the outside of these Muscles, whether they contain any; for generally such as have them are a little contracted or distorted from their usual shape. A curious and accomplished Gentleman, lately of these parts, showed me a valuable Collection of the Pearls of the Conway River in Wales; amongst which I noted a stool-pearl [button-pearl], weighing seventeen grains, and distinguished on the convex side with a fair round spot of a Cornelian colour, exactly in the center.[191] In 1560 “large handsome pearls” were sent from Scotland to Antwerp.[192] In 1620 a great pearl was found in the Kellie Burn, in Aberdeenshire. This was carried to King James by the provost, who was rewarded with “twelve to fourdeen chalder of victuals about Dunfermline, and the Customs of Merchants’ goods in Aberdeen during his life.” No record appears of the reward paid to the finder; possibly it was not worth recording. In 1621 the Privy Council of Scotland issued a proclamation that pearls found within the realm belonged to the Crown; and conservators of the pearl fisheries were appointed in several of the counties, including Aberdeen, Ross, and Sutherland. It was the duty of the conservators, among other things, to nominate experts to fish for pearls during July and August, “when they are at chief perfection.” The conservators and fishermen were compensated by selling those pearls of ordinary quality, but “the best for bignesse and colour” were to be remitted to the king. It was reported to the Privy Council that the conservator in Aberdeenshire did very well in the first year. “He hath not only taken divers pearls of good value, but hath found some in waters where none were expected.” The first parliament of Charles I abolished these privileges. Robert Sibbald, physician to Charles II, wrote that he had seen a necklace of Scotch pearls which was valued at two thousand crowns; they were “larger than peas, perfectly round, and of a brilliant whiteness.”[193] It is said that Sir Richard Wynne of Gwydir presented to Catherine of Braganza, queen of Charles II of England, a pearl from the Conway in Wales, which is said to be even yet retained in the royal crown. In his “Faerie Queene” (1590), Spenser speaks of the Conway, which out of his streame doth send Plenty of pearles to deck his dames withal.
