Sapphire and Diamond 'étoile Du Nord' Clip-brooch Cushion-shaped Sapphire of 9.37 Carats, Round Sapphires and Diamonds
A cushion-shaped sapphire weighing 9.37 carats anchors this clip-brooch, a stone of genuine scale set at the centre of a composition built specifically to showcase it — round sapphires and diamonds surrounding the central stone in a halo arrangement, mounted in 18k yellow gold and platinum. Sapphire of this size in cushion cut carries real rarity: the cushion shape retains more of the original rough than many modern cuts, meaning a 9.37-carat finished stone likely began as a considerably larger piece of rough material, and finding sapphire rough capable of yielding a clean stone at this weight is itself an uncommon event in the gem trade.
Colour grade and clarity for the central sapphire are available on request. What can be confirmed with confidence is the carat weight and cut, verified directly against the piece, and the two-metal construction — platinum almost certainly forming the central setting for maximum security and a cool-toned frame around the sapphire, with the yellow gold carrying the surrounding structure and warming the overall composition. This kind of considered metal choice, using each material where it performs best rather than defaulting to a single metal throughout, is characteristic of the finest period workshops of the era.
As a wearable piece, a brooch built around a stone of this scale becomes the natural focal point of any outfit it joins — pinned to a lapel, it commands attention without requiring additional jewellery nearby; gathered at a neckline, it functions almost as a sculptural pendant in its own right. Sapphire at nine-plus carats, in a clean cushion cut with confirmed halo construction, represents precisely the kind of centre-stone brooch that collectors acquire specifically because comparable material becomes harder to source with each passing year that goes by.
Our workshop has inspected the clip mechanism and central setting security given the scale of the central stone, and we recommend periodic professional inspection for any brooch carrying this level of central stone weight. Independent gemmological certification for the 9.37-carat sapphire and surrounding diamonds is available on request, and our specialists are glad to discuss colour, origin where documented, and clarity in detail with any serious enquiry that reaches us.
This brooch bears the Legacy signature as a substantial sapphire centre-stone design. To request the full gemstone report or arrange a private viewing, please contact our client advisory team — we welcome the opportunity to discuss a piece of this calibre in depth.
