The Telegraph’s Sunday magazine in August 1981 offered in one advert – ‘The Royal Ring’ made by RJW. “A ring of rare beauty and exquisite detail carefully crafted to follow the design of the Royal original.”
Down in Hatton Garden, skilled craftsmen were hammering them out with a sapphire surrounded by diamonds. “Precision set in yellow or white 9 carat gold with a very special rodium plate finish to the mount”.
Rodium, it turns out, is a member of the platinum family. So there you go. Something I never knew.
The normal RRP was £150 but the “Important Announcement price” was “just” £79.95. You could also get matching earrings and pendant and “impressive gift boxes”.
