Weekly since 1980
July 30, 2026
News:
$1B reported De Beers price tag reflects industry’s multiyear downturn. De Beers trims 1H underlying loss to $188M amid cost controls. Sentiment improving in India, stable in US, as supply tightens. US tariffs on Indian goods stay at 10%; Belgium, Botswana and Namibia secure 0% rate. No clear impact on prices or inventory. Round prices under 1 ct. improving, 1 ct. mixed. Demand for 2 ct. and larger steady, with rough hard to find and going to a small number of companies. LVMH (Tiffany, Bulgari) and Kering (Boucheron, Pomellato) report strong jewelry sales in US and Asia. Big stones boost Gem Diamonds: 1H sales +33% YOY to $59.5M, average price +38% to $1,395/ct.
Fancies:
Long fancy shapes such as Ovals, Marquises and Emeralds doing better than rounds in 2 ct. and larger. High-quality Marquises, long Radiants and long Cushions in short supply. Marquise most expensive fancy shape. Long Cushions easy to sell and trading at 20% to 25% premium over square ones. Antique cuts and styles hot. Solid US market for elongated Ovals of good shape and quality in D-I, VS-SI categories. Very well-cut fancy shapes difficult to find and commanding premiums. Fancies with bad proportions illiquid.
Country Comments
United States
Market steady and mood positive. Difficult to replenish quality inventory. Low-color diamonds attracting buyers. Industry expecting business to pick up toward end of August as retail jewelers seek natural diamonds following summer break.
Belgium
Market quiet during summer holidays. Industry watching closely as 0% US tariff rate could position Antwerp as a more competitive manufacturing hub for large diamonds.
Israel
Market quiet during summer holidays. Industry under pressure from tariff disadvantage as US imposes 12.5% duty, with some calling for government support. Nissim Zuaretz resigns as Israel Diamond Exchange (IDE) president.
India
Sentiment positive ahead of IIJS show in Mumbai (August 5 to 10). Prices firm and inventory tight, with buyers struggling to source desired goods. Round, 0.30 to 0.69 ct. diamonds seeing solid recovery. Round, 2 ct. and larger diamonds performing well; 2.50 ct., G-K, VS-SI in good demand. Ovals improving. Pears performing well; long radiants and cushions moving steadily in 2 ct. and larger, F-I, VS-SI qualities. Trade expecting good Diwali season for domestic jewelry market.
Hong Kong
3 ct. and larger, D-F, IF-VS2 diamonds supporting market. Long fancies outperforming rounds in 2 ct. and larger. More businesses shifting focus from smaller stones to larger, certified goods. Goods under 1 ct. slow. Chinese wholesale market quiet but better than the same period last year, with demand concentrated in round, 1 to 2 ct., GIA-graded goods.
