This clip-brooch pairs two substantial centre stones — a 4.39-carat cushion modified brilliant-cut diamond and a 5.67-carat sugarloaf-cut emerald — surrounded by old, single, baguette-cut, square-shaped and round diamonds plus baguette-cut emeralds, the entire composition mounted in platinum. Sugarloaf cutting, a domed cabochon-style cut with a pointed peak, was a favoured Art Deco treatment for emerald specifically because it showcased colour saturation and depth in a way faceting could not, and pairing a sugarloaf emerald of this weight against a cushion diamond of comparable carat size represents a genuinely ambitious two-centre-stone composition.
Colour grade and clarity for both centre stones, along with the full accent diamond and emerald specification, are available on request. The variety of diamond cuts surrounding the two centre stones — old, single, baguette and square-shaped alongside round brilliants — reflects the Art Deco period's compositional sophistication, each shape contributing structure to the geometric framing around the dual centre stones. Platinum was the only realistic mounting choice for a piece carrying this concentration of value and this many individual settings, offering the strength to secure every stone permanently while contributing its own cool, understated frame.
As a wearable piece, a clip-brooch anchored by two centre stones of this scale becomes an unmistakable focal point — pinned to a lapel, it commands attention through composition and colour contrast rather than size alone, the emerald's green and diamond's white trading visual dominance depending on the light. Dual centre-stone Art Deco pieces of this ambition are genuinely scarce in the current market, since assembling two stones of comparable weight and complementary quality required exceptional sourcing even at the time of original construction.
Our workshop has inspected the clip mechanism and both centre-stone settings given the scale and value concentrated in this piece, and we recommend the same level of periodic professional inspection going forward. Independent gemmological certification for both centre stones and the full accent parcel is available on request — documentation we consider essential for a piece of this calibre. Two-centre-stone Art Deco brooches of this ambition were typically reserved for the most significant commissions a workshop undertook, and the sourcing effort required to pair a sugarloaf emerald against a cushion diamond of comparable weight represents a level of achievement rarely matched by later reproductions.
