Giant Moonstone Ring
Moonstone has fascinated us for millennia. Legends talk of moonstone's ability to bestow good luck on the wearer, and Hindu mythology claims that the stone is made of solidified moonbeams. Its lunar connection has given moonstone a strong association with the divine feminine, indeed the ancient Greeks and Romans paired the stone with their respective moon goddesses, Selene and Diana.
Moonstones were once known as "adularia", named after the city in Switzerland, Mt. Adular, where to finest quality moonstones were once found, we still call the mesmerising optical effect whereby a shimming blue haze appears to swirl and shimmer inside the stone "adularescence".
They were popular with the great designers of the Art Nouveau movement - René Lalique and Louis Comfort Tiffany - and also with the jewellers of the Arts and Crafts era on account of its wonderful pairing with silver (not just gold).
A gigantic blue moonstone forms the centrepiece of this remarkable ring. At over 18 carats in weight, and displaying exceptional blue adularescence and good transparency, it is a rare stone indeed - worthy of setting in a rather special ring. A 22 carat gold Roman-style double bezel secures the stone, the rich, butter gold tone providing the perfect complement to the blue shimmer, and the rest of the ring is solid and substantial, crafted in 18 carat gold.
