Carat8.41-carat pink diamond carries a HK$95m Christie's estimate
The pear-shaped type IIa stone is graded fancy vivid purple-pink, which works out at HK$11.3m a carat. A Cartier brooch set with a 10.10-carat Burmese ruby carries HK$60m at the same 24 November sale.
Christie's set the range. An 8.41-carat fancy vivid purple-pink diamond ring carries a HK$95m high estimate at Christie's Hong Kong sale on 24 November.
If you price pink goods: the estimate works out at HK$11.3m a carat across 8.41 carats.
If you bid in Hong Kong: two named lots carry HK$155m of high estimate between them.
What this is not: a result. Both figures are pre-sale estimates and the sale is in November.
| Lot | High estimate, HKD | High estimate, USD | Per carat, HKD |
|---|---|---|---|
| 8.41 ct fancy vivid purple-pink diamond ring | HK$95m | $12m | HK$11.3m |
| Cartier brooch, 10.10 ct Burmese ruby | HK$60m | $7.7m | HK$5.94m |
| Both lots | HK$155m | $19.7m | not comparable |
IOne stone, two currencies
HK$95m published. Christie's carries the ring at HK$95m, reported with a US figure of $12m.
The rounding shows. That pair implies HK$7.92 to the dollar. The Hong Kong peg trades between HK$7.75 and HK$7.85, so the dollar figure is rounded rather than converted.
IIThe ruby costs less a carat
Cartier's brooch follows. A brooch set with a 10.10-carat Burmese ruby carries HK$60m, the second lot Christie's named.
Half the per-carat. The ruby works out at HK$5.94m a carat. That is 52.6% of the diamond's rate and 47.4% below it.
IIINo low estimates published
Only the tops. Christie's published no low estimate for either lot, so neither a band nor a reserve can be read from the announcement.
The sale is later. Bidding opens on 24 November in Hong Kong, ten weeks after the announcement.
01What would change this call+
A published low estimate on either lot. A band would show how far Christie's thinks the ring could fall, and a low near HK$60m would make it a different lot from one near HK$95m.
02How a Hong Kong estimate reads+
A house publishes a low and a high estimate before the sale; the reserve, the price below which a lot will not sell, is confidential and sits at or under the low. Hong Kong sales are struck in Hong Kong dollars, which the territory pegs to the US dollar inside a band of HK$7.75 to HK$7.85. A US figure quoted alongside an HKD estimate is therefore usually a rounded courtesy rather than a conversion at the day's rate. The buyer pays the hammer price plus the house's premium, so any sum paid sits above the figure a result reports.
03Method · the desk’s arithmetic+
Rapaport's report of 15 September 2026 was fetched directly and carries the carat weight, the colour grade, both estimates, the house and the sale date. christies.com was not fetched and no address was guessed in its place. Arithmetic, all Carat Capital's and printed so it can be checked: 95,000,000 divided by 8.41 is HK$11,296,076 a carat, and 12,000,000 divided by 8.41 is $1,426,873 a carat; 60,000,000 divided by 10.10 is HK$5,940,594 a carat. The comparative was redone here rather than taken from any upstream desk: 5,940,594 over 11,296,076 is 52.59%, so the ruby is 52.6% OF the diamond's per-carat rate and 47.4% BELOW it. The implied exchange rates are 95 over 12, which is HK$7.9167, and 60 over 7.7, which is HK$7.7922; the first sits above the peg band's HK$7.85 ceiling and the second inside it, which is why the dollar figures are treated as rounded and the HKD figures as primary. The ten weeks is 15 September to 24 November, seventy days. Archive test, both periods named: a grep for 8.41 returns five hits in this paper's archive and all five were opened and read, every one a gold-to-silver ratio (68.41, 67.84, 67.49, 66.59) in August metals commentary, so all five are false positives. Carat Capital's 15 September piece covers a Christie's GENEVA sale on 10 November and a 14.63-carat David Morris ring; this item covers a Christie's HONG KONG sale on 24 November and an 8.41-carat stone. Same house, different sale, different city, different stone, different date, so NEW.
