The Kiki McDonough Citrine Cushion earrings are a specific design from the British designer's catalogue, consisting of cushion-cut citrines suspended as drops below smaller round-cut citrines or diamonds. The design has been worn on multiple public occasions by Catherine, Princess of Wales, contributing to the wider recognition of the McDonough brand outside Britain.

Design

The earrings combine two elements: a smaller citrine or diamond stud at the upper position, against the earlobe, and a larger cushion-cut citrine drop suspended below by a short connecting link. The cushion shape is the rounded-corner squarish cut traditional in coloured-gemstone work, allowing depth and colour saturation to be displayed without the more aggressive geometry of a true square cut. The mounting is typically 18-carat yellow gold, with claw or open-back settings designed to allow light to enter the back of the citrine and lift the colour.

Material

Citrine is the yellow to orange variety of crystalline quartz, coloured by trace iron in the lattice. Most commercial citrine is heat-treated amethyst or smoky quartz, with the heat treatment converting the original purple or brown to the yellow-orange citrine colour. The treatment is stable, permanent, and accepted in the trade; it is required to be disclosed under standard industry practice but does not carry a discount because untreated material in this colour is rare. McDonough's citrine, like the bulk of the trade's, can be assumed heated unless documented otherwise.

Royal wearing

The Princess of Wales has worn the Citrine Cushion design at multiple public engagements, including events in 2012 and subsequent appearances. Each public wearing has produced press attention, and the design has at points sold out following such appearances. The pattern is now familiar to British jewellery commerce: a piece worn by the Princess sees an immediate spike in demand, and McDonough has been one of the most visible beneficiaries.

Position in the McDonough range

The Citrine Cushion sits firmly within the McDonough core range of coloured-gemstone earrings, neither the most ornate nor the simplest in the catalogue. Variants in different stones, including amethyst, blue topaz, and green amethyst, follow the same architecture of small upper stud and larger cushion drop. The consistency of the architecture across stones is part of how the McDonough aesthetic is recognisable.

Trade significance

For the trade the design illustrates the commercial value of a clear, repeatable architecture combined with a plausibly accessible price point in the low to mid four-figure pound range. The royal patronage has been significant but the design predates the patronage and would be a credible commercial product on its own. For working jewellers it is a useful reference for how a moderately priced coloured-gemstone earring can sustain attention and demand over more than a decade.

Variants and second-market presence

Cushion-shaped citrine drop earrings of generally similar architecture are produced by many other makers; the McDonough version is recognisable through its specific proportions, the choice of citrine quality, and the particular gold-tone setting. Buyers should rely on documented provenance from McDonough or its authorised retailers for any piece represented as the McDonough Citrine Cushion design rather than on visual similarity alone.
