A Still Board, a Shifting Structure, and a De Beers Sight Days Away
Polished prices have not moved since September's RAPI, but De Beers ownership, a two-year Venetia pause, and a revocable U.S. tariff waiver all shifted under a quiet market.
The polished price board did not move this week. Quotes sit where September's RAPI left them, with the 0.50-carat grade up 2.5% for the month and the one-carat grade up 0.3%, and no new index, sight result, or tender to reprice inventory. The quiet is only the surface. Under it, the industry's ownership, supply, and trade-policy questions all shifted, and next week forces several of them into view.
The board stays quiet, and demand explains why
September's reading, led by the smallest goods, is still the last firm price point the trade has. The calm is not a pause in a recovery. India's September gem and jewelry exports grew 9.43% to $2.95 billion, but cut-and-polished natural diamonds came in at $1.29 billion, down 5.44% on the year (GJEPC). The gain sits in gold and lab-grown goods, not in natural stones. So the flat board reflects natural-diamond demand that has not yet turned, and the small-stone lead remains the only firmness on the sheet. The next figure that can change inventory valuations is the October RAPI in early November.
Currencies and metal moved where prices did not
Two currencies and one metal did the week's work. The rupee held the turn we have tracked since mid-October, settling near 94.47 per dollar. It firmed past the 1.5% weekly line that matters for quoting earlier in the month, and this week's 0.73% move stays below that threshold, so the level holds even as the weekly change has cooled. For Surat, a firmer rupee trims what exporters collect on dollar sales while making imported rough a little cheaper in local terms.
Gold fell 6.14% since September 22, a cost signal for jewelry metal rather than for stones, and the shekel near 3.09 is a financing factor for Ramat Gan desks, not a change in the dollar-quoted stone.
Trade policy delivered the week's one real scare and then withdrew it. President Trump signed an executive order on October 16 that set a 100% duty from the Graham sanctions act on the largest buyers of Russian energy, India among them, then suspended it through a waiver with no fixed expiry (Outlook India, The Tribune). The tariff step several reports had flagged for around October 18 never reached Indian goods. Our assessment is that this is a reprieve the administration can withdraw, not a settled exemption, so the risk is paused rather than closed.
The structure kept shifting
While prices held, the structure around them did not. De Beers reported lower third-quarter production and is winding its Venetia mine toward a two-year pause (National Jeweler). Taking a long-running mine offline points to supply discipline at that mine, but it is not a cut to overall supply: the same report raised full-year production guidance to 25 to 28 million carats, from 21 to 26 million, and the average realized price so far this year is 37% below last year's, so price has already given way. A multi-year suspension also cannot be reversed quickly once demand returns.
Ownership stayed unresolved. We logged a mid-October call for Botswana to settle its position on the De Beers stake, and that date passed with the talks still open. JCK now reports Botswana moving to raise its holding, while Richemont and Signet are said to be in talks to join the consortium bidding for Anglo American's stake. For sightholders, the live question is not this morning's price but who controls rough allocation and the terms of future sights into 2027.
The Week Ahead
- De Beers Sight 9, October 26 to 30 — the first firm reading on rough pricing since September. Last week, we logged the expectation that De Beers holds or trims rather than raises. This is the test.
- JA New York Fall (October 25 to 27) and the Dubai Diamond Conference (October 26) — the trade gathers in the same stretch, providing the earliest live signal on U.S. holiday demand and Gulf appetite.
- October RAPI, early November — the first firm polished print since September and the check on whether the small-stone lead held or faded.
- The U.S. tariff waiver — it carries no fixed expiry, so the risk is a decision to withdraw it, not a date on the calendar.
