The heart of the ocean

A natural 8.50 ct sapphire in an Art Deco platinum & diamond ring, circa 1930

The memory of some special jewels is deeply etched in our collective memory. Some of them actually exist, like the blue Hope diamond or the yellow Tiffany. Others live only in memory or imagination, like the spectacular blue "heart of the ocean" that drives and conditions the plot of James Cameron's 1997 Titanic as a central anchor point. Looking at this spectacular ring from the Art Deco years, that heart of the ocean came to mind. Not because of the ship's sinking, of course, but because the spectacular, large sapphire at its center equally beguiles the senses and immerses the gaze in the infinite expanses of Neptune's realm. The ring in platinum sets the large, natural sapphire as the highlight of the design in a double frame of diamonds. Against this backdrop of white sparkle, the deep, slightly violet blue of the stone shines particularly impressively; the oval that the stone prefigures is very slightly multi-passed towards the edges, creating a slightly moving surface. It is a colour that is both beguiling and soothing, which runs through the stone in bands of varying intensity. The special quality of the sapphire has also been confirmed by an independent gemmological laboratory. The corresponding certificate of appraisal, shown here, is of course included with the ring. The ring, created in Germany around 1930, is in first-class condition and came to us from a distinguished estate in the Rhineland.

The sapphire is a truly royal stone. Even more frequently than the ruby, it adorns the crowns of the monarchies of Europe: the English state crown sparkles in the light of 18 beautiful stones, and that of the Bohemian king Wenceslas has just as many. And yet it shares many properties with the ruby, because for the mineralogist both stones belong to the group of corundum. The most famous sapphires in the world come from Kashmir, where today only a few sapphires are mined. Kashmir sapphires show a powerful cornflower blue and have a so-called "sleepy", slightly milky character. Sapphires from other sites show different shades of blue: stones from Mianmar, which can also reach the highest qualities, tend more towards an ultramarine. Sapphires from Sri Lanka tend to shine in a lighter, sky-blue tone. Sapphires from both locations tend to show stronger inclusions. It should not be forgotten, however, that sapphires can be more than just blue! Because like the ruby, the sapphire belongs to the corundum group. Since in mineralogy all corundums are called sapphires with the exception of the red ruby, yellow, green and orange sapphires are encountered in addition to the blue varieties. These stones, if they have an outstanding color quality and are free of inclusions, also fetch high prices in the trade. The pink to orange variety of sapphire is particularly sought after: these stones come exclusively from Sri Lanka and are known as Padparadscha. Today, however, the colour of stones from other regions is often altered by technical treatment and then also sold as padparadscha. In popular belief, the sapphire is considered the stone of truth, loyalty, wisdom and reason. Accordingly, the Doge of Venice wore such a mild blue stone as a sign of his fidelity and marriage to the sea, set in gold. And Queen Elizabeth I of England also believed that her sapphire could protect her against slander and cunning.
