CaratChristie's estimates a David Morris ring at up to $2.6m
The 14.63-carat fancy orangey-pink stone leads nearly 300 lots from a single private collection. The live sale is on 10 November in Geneva, with an online sale running 5 to 17 November.
Christie's set the range. A David Morris ring set with a 14.63-carat fancy orangey-pink diamond carries a high estimate of $2.6m at Christie's Geneva sale on 10 November.
If you bid on coloured diamonds: the ring is the highest-estimated lot named out of about 300.
If you value pink goods for clients: seven named lots carry high estimates from $500,000 to $2.6m.
What this is not: a result. These are pre-sale estimates and nothing has sold.

IOne collection fills two sales
Nearly 300 lots. Christie's will offer close to 300 lots from a single unnamed private collection across the two sales.
Two dates, two formats. The live sale runs on 10 November in Geneva and the online sale from 5 to 17 November.
IIFour lots carry one maker
Four named lots. Four of the seven lots named in the announcement are Van Cleef & Arpels, estimated between $300,000 and $1m.
Graff and Bulgari follow. Graff emerald earrings carry $900,000 to $1.5m and a Bulgari Trombino ring $700,000 to $1.2m.
IIIThe estimates are not results
Six bands published. Six of the seven named lots carry both a low and a high estimate, totalling $3.5m and $5.6m.
One is open-ended. Only the upper figure is published for the David Morris ring, so it sits outside both totals.
01What would change this call+
A published low estimate for the David Morris ring. A band would place the stone against the rest of the collection, and a low near $1.5m would make it a different lot from one near $2.6m.
02How an auction estimate is set+
A house publishes a low and a high estimate before the sale, based on comparable results and on the consignor's expectations. The reserve, the price below which the lot will not sell, is confidential and sits at or under the low estimate. A buyer pays the hammer price plus the house's buyer's premium, so the sum paid is always above the hammer figure a result reports.
03Method · the desk’s arithmetic+
The announcement was read through Rapaport's report of 14 September 2026, timestamped 15:30:48 UTC in its own structured data and fetched directly. Christie's own sale page was not reached: christies.com refused this desk's fetch, and no address was guessed in its place under the Address Rule. That is a disclosed gap, not a dressed-up citation. National Jeweler's headline about 300-plus coloured diamonds at Christie's was checked and not used, because it is not this sale. Arithmetic, Carat Capital's: the six lots with both figures published total 900,000 plus 700,000 plus 600,000 plus 600,000 plus 400,000 plus 300,000, which is $3.5m at the low end, and 1,500,000 plus 1,200,000 plus 1,000,000 plus 800,000 plus 600,000 plus 500,000, which is $5.6m at the high end. The David Morris ring is excluded from both totals because only its upper figure is published. Archive test, both periods named: Carat Capital's archive carries David Morris in six files, all covering a pearl-and-diamond necklace sold at Bonhams London on 8 July 2026 for GBP 40,960; this item covers a Christie's Geneva sale on 10 November 2026 and a different object. Same brand name, different house, different stone, different sale, so NEW.
