Stunning and unique 7.16 carat natural Blue Star Sapphire, Diamond and 18ct Gold Ring from Hatton Garden: sold

The quality of a star sapphire depends on many elements, including the star’s orientation and the cabochon’s symmetry, proportions and finish. And this natural Ceylon star sapphire has it all: wonderful symmetry and quality, the blue of the sapphire perfect to display the bright rays of the star. It has all the qualities the world’s gemologists seek: the star’s rays are uniform in strength, they reach from one side to the other, and they intersect at the top of the stone. They are straight, not fuzzy or broken, and contrast strongly against the beautiful blue of the sapphire. This star also has elegant ‘movement’, in that, as you rock the stone, the brilliant star moves smoothly across the surface. We are thrilled to have this unique and exquisite ring for our Members—particularly as the gemstone for September is the sapphire.

The scientific term for the natural gemological phenomenon of a star sapphire is asterism. When light is reflected off the stone’s inner ‘silk’, a star effect is created on the face of the stone. Asterism is rare, and increases the value of the stone. The star sapphire is also filled with symbolism: star sapphires surpass even regular sapphires in their reputed mystical power. Star sapphire is known as the ‘Stone of Destiny’, with the power to heal: sapphires have long been regarded as revealing the ‘third eye’, giving the wearer strength and health, warding off illness. This is in addition to the sapphire’s association with devotion: sapphire is thought to bring peace and contentment, as well as constancy and true love.

Whatever the meanings of the stone, this ring is a beautiful, natural, eye-catching piece of precious jewellery, a gorgeous addition to a woman’s jewellery collection, and one which will become a family heirloom. The gem is large enough to make a mesmerising impact, the diamonds flashing in a coronet of white fire—and suddenly that flash of the sapphire star appears, magnetising all who see it. So if you seek a show-stopping precious gem which is entirely natural and original, this may well be the one.

The blue star sapphire gemstone is 7.16 carats and the diamonds are .83 carats, F/G in colour and VS in clarity, and therefore in the top three for quality—very white and flawless to the eye. The ring measures 15mm by 13mm diameter. There is one only.
