A sapphire exceeding sixty-five carats is a genuine rarity in the jewellery trade, and this clip-brooch is built around exactly that: a cushion-shaped sapphire weighing 65.46 carats, set as the commanding centre of a platinum and 18 karat white gold mounting. Surrounding round brilliant-cut diamonds, ranging in size from 2.12 down to 1.60 carats, frame the sapphire with substantial individual stones rather than the small pavé accents more typical of lesser pieces — a choice that signals confidence in the centre stone and in the overall composition.
Colour depth, clarity characteristics and full diamond weight totals are available on request; sapphires at this carat weight are judged first on colour saturation and evenness, and clients seriously considering this piece are encouraged to request full gemmological notes and independent certification before proceeding, given the scale of the stone involved. The cushion shape chosen for the centre sapphire is a traditional cut for large corundum, favoured for the way it retains weight while allowing colour to read with maximum depth across the stone's face.
As a clip-brooch, the piece is engineered with a double-clip fitting rather than a single pin — a mounting style favoured historically for larger, heavier stones precisely because it distributes weight across two points of contact on the fabric rather than one, reducing strain on delicate fabrics and on the mount itself over years of wear. This is a meaningful distinction for a stone of this mass, and it reflects serious engineering rather than decorative afterthought.
A sapphire of this size is, in practical terms, a collector's acquisition first and a wearable brooch second — though it remains entirely suited to formal evening wear, worn at the shoulder of a structured gown or the lapel of formal eveningwear where its scale can be appreciated without distraction from surrounding pieces. Sapphires of this carat weight and quality rarely reappear on the market once placed in a serious collection, making acquisitions like this one as much about securing scarce material as about the finished piece of jewellery.
Given the significance of the centre stone, independent laboratory certification is available on request, and we recommend it as standard practice for an acquisition of this scale. This clip-brooch has been entered into the Legacy house register among our most notable sapphire holdings, a designation reserved for stones of genuine, verifiable rarity.
Our senior client advisors are available for a private, confidential consultation to discuss the sapphire's characteristics, provenance, and acquisition terms in full detail. We welcome the opportunity to arrange an in-person viewing at your convenience.
