One of the most magical gemmological phenomena is known as ‘asterism’ or the star effect. This extremely rare attribute is caused by tiny rutile needle-like inclusions within the gemstone which intersect and align to create a shimmering star when viewed under a light source.  Stones with these inclusions are cut ‘en cabochon’ to best display this unusual optical quality. 

A hot topic in global news at the moment is that the world’s largest star sapphire has been recently discovered in Sri Lanka, weighing an astonishing 1404.49 carats and is believed to be worth in excess of $100 million USD. This gemstone is obviously too large to be mounted and worn as jewellery, however if you are looking for a star sapphire which can be worn and enjoyed, take a look at the following antique and vintage star sapphire rings currently available in Berganza’s stock.
