Stoop, I fully expected the shop to make a profit so paying, say £60.00 would have been fine with me, but £100 was just greedy!!
Another point is, British Gold is much higher quality than foreign gold, which is why, at auction a British piece will always make more money. I always notice, when a Foreign piece comes up at Auction the Jewellery buyers will never bid as much money, they always want to see British Hallmarks on pieces.
