Margot Robbie wore a 100‑carat diamond necklace to the “Wuthering Heights” Paris premiere, a rare high‑carat display whose visibility is likely to reinforce private‑sale interest and purchasing appetite for top‑tier diamond pieces among high‑net‑worth clients and collectors.

Context: where a 100‑carat moment fits in 2025–26

Large‑carat necklaces remain a signalling device in luxury jewellery: the substantial heft and vitreous luster of a 100‑carat assembly reads as rarity and purchasing power. In a market that has seen both lab‑grown diamond price compression at accessible tiers and targeted growth in private sales for exceptional stones, high‑carat red‑carpet placements perform two functions — they demonstrate what the top of the category looks like, and they refresh the desirability of fixed‑inventory, certificate‑backed pieces for private clients.

For design and merchandising, the effect is often aesthetic rather than novelty. Retailers and houses place emphasis on refined settings (knife‑edge shanks, open‑backed mounts for light performance) and finishing that showcases scale and clarity without ostentation. Provenance, grading and the quality of craftsmanship become primary talking points during private viewings; visible moments on the red carpet supply the storytelling that supports those claims.

Impact: why US retailers and investors should pay attention

For US retailers and wholesalers, the immediate implication is merchandising and inventory strategy. Expect heightened demand for appointment‑only showings and private‑sale channels for high‑carat diamonds following prominent red‑carpet appearances. Buyers attracted by such moments typically prioritise certification and provenance; sellers should ensure clear grading documentation and controlled inventory presentation rather than broad public discounts.

From a category perspective, this kind of celebrity placement can widen the gap between the high‑jewellery tier and accessible diamond offerings. Marketing should lean into restrained, quiet‑luxury narratives: emphasise tactile qualities (substantial heft, precise facet polish, satin‑finished clasps) and the bespoke experience of acquisition. For investors and buyers, visibility for exceptional pieces tends to support private‑sale liquidity and reinforces the value proposition of certified, well‑documented stones at the top end of the market.
