What are cluster rings? A cluster ring France is called a “marguerite”, the daisy flower. Then you understand that’s a name given to a broad range of ring styles with one thing in common : gemstones ‘clustered’ together. Most of the time there is a central stone in an entourage of smaller stones. They come in a wide variety of shapes: round, oval, square. Cluster rings can be set with all types of stones, but the great classic is the ring with a central sapphire surrounded by diamonds, like Kate Middleton’s ring.

More information : there are several examples of rings identified as Italian in the British Musuem, and although it is known that these designs were also made in Spain, there are no Spanish models referenced in museums. However, this style can be found throughout Southern Europe: Italy, Spain and Portugal, and can be explained by the presence of the Habsburgs during the 16th and 17th centuries in regions such as Sicily, Sardinia, Naples and Milan.

Gemology and beliefs: Opals come in various types, with noble opals being the kind that exhibits play-of-color. This captivating effect is caused by tiny, uniformly sized spheres of silica. When light hits these spheres and is refracted, it produces a dazzling display of colors on the opal’s surface. In contrast, common opals lack this play-of-color, as their spheres are disordered and of varying sizes, giving them a milky appearance. Opals have been associated with the power of invisibility in folklore, earning them the title “Patronus forum” (patron of thieves) during the late Middle Ages.
