A pink star sapphire
Cluster ring with natural star sapphire & 1.26 ct diamonds, circa 1880/1970
When you think of sapphires, the first thing that comes to mind is blue gemstones. However, the range of colors that genuine sapphires have to offer is far greater. Depending on the deposit and the elements involved in the formation of the stones, sapphires can occur in almost every color of the rainbow. Sapphires with particularly expressive colours are especially sought after, which is why we are especially pleased with the beautiful, delicate pink sapphire in this white gold ring. This precious ring with its 19th century ring face features a wonderful natural star sapphire in its center. Shaped as a tall cabochon, the gemstone has a beautiful pink color that glows intensely. In optimal and selective light, the gemstone exhibits an inner glow that seems to travel across the body of the sapphire. This effect, known as "asterism", is caused by inclusions of the mineral rutile, whose needle-shaped crystals refract the light in this special way. A ring of ten sparkling old-cut diamonds with a total weight of approximately 1.26 carats surrounds the sapphire. With their white colour contrasting with the sapphire, they bring out the pink of the coloured stone particularly well. They are set in side-closed settings, typical of the ring's period of origin, which gives the ring head a compact appearance. The ring band was apparently renewed in the 1970s and is made of white gold. The ring head is forged from silver and the whole ring is also fully rhodium plated. As a result, it now glows a flawless bright and uniform white. A truly exceptional piece of jewellery of heavenly elegance.
Asterism (from Greek ἀστήρ (aster) = "star"), also called star of light or star shine, is understood in mineralogy and gemmology to be star-shaped light reflections in crystals. The special light reflections are produced by fine crystal fibers or needles that are embedded in the host crystal in question and meet at a point when ideally distributed. The more evenly the needles are arranged, the more harmonious and beautiful the light star appears. Depending on the crystal system and class of the mineral in question, 4-, 6-, 12- and 24-rayed stars occur. In the case of rose quartz, circular asterism can also occur. Asterism is preferentially seen in sapphire and ruby, the varieties "star sapphire" and "star ruby" have therefore also been named after this effect. The asterism is particularly emphasized by the corresponding cut (cabochon cut).
