Sotheby's Hong Kong
How did we miss this one?
Sotheby’s Hong Kong Magnificent Jewels I on October 7th, 2022, was quite the auction for impressive gems. Just a few that caught our eyes were the following:

A Fancy Vivid Orange-Yellow Diamond and Diamond Ring
Estimated between 5,000,000 – 8,000,000 HKD, the lot sold for 8,568,000 HKD (approx. USD$1.1 million)

Note: the color is "Orange-Yellow." This means that the diamond has approximately the same amount of yellow as it has orange. Listing the Yellow color last is a subtle way to let you know that there is possibly more yellow than orange, but not by much. This is not a measured color but a visual comparative estimation. - gr

The Auction Market - Rapaport
The Auction Market Is Becoming Harder to Forecast
by Anthony Demarco

For the past 15 years, momentous events — including wars, recessions and Covid-19 — have had little impact on the auction market for gems and jewels. During the worst and best of times, the monied class has viewed hard luxuries like jewels and watches as sound investments and collectible items of beauty. In addition, auction houses have proven agile in developing creative and innovative ways to sell their items. Some auction-house officials say ...

1 Sapphire, from 3 Different Countries?
from Sotheby's HK Magnificent Jewels Auction / October 2022
What does it mean when a sapphire receives 3 Country of Origin reports and each country is different?

Here’s the background.

In the October 2022 Hong Kong Sotheby’s auction, there was a beautiful sapphire and diamond ring up for sale. A 10.06 carats sapphire, estimated at 400,000 to 700,000 HKD (USD$50,000-$90,000) that sold for 756,000 HKD (USD$96,000) A tidy sum. And in the description of this ring, there were three laboratory reports, one that stated country of origin being Madagascan, one that stated Burmese, and one that stated Sri Lankan (Ceylon).

Let’s not argue over the science of origins. For one thing, these laboratory differences/disagreements are much more rare than most people think. And speaking of rare, we rarely hear about the times the labs agree on challenging identifications. But everyone talks about the discrepancies, most likely because they are the most challenging to identify.

AGA - Conference and Bonanno Award
(TUCSON, Ariz. – Feb. 1, 2023) – It was a day of learning and an evening of celebration!

And a few years of catching up.

Tucson. Finally in-person, the Accredited Gemologists Association's day-long conference was packed with impressive learning sessions, some traditional theatre classroom style presentations, and a few small group hands-on labs.

The evening was partly a celebration to be back in person with friends and colleagues, but also to finally present the Bonanno Award for Excellence in Gemology that was to have taken place last year, 2022.

Seen here in the photo above, all past recipients of the Bonanno Award, left to right, Stuart Robertson, Thom Underwood, Robert Weldon, Richard Drucker, Dr. James Shigley, Antoinette Matlins, Gary Roskin (this year's recipient), Shane McClure, Donna Hawrelko, Richard Hughes, Dr. Çiğdem Lüle, Mikko Åström, John Koivula, and Alberto Scarani.

Cambodia - Recovered Looted Jewelry
Feb. 20, 2023

Cambodia Says It Has Recovered Looted Gold Jewelry Once Worn by Royals

The 77 items had been in the collection of Douglas A.J. Latchford, accused of trafficking in looted antiquities, and were returned under an agreement with his estate.
Dozens of pieces of very old gold jewelry believed to have once been worn by Angkor royalty, like this diadem, have been returned to Cambodia.

Some were jewel-encrusted diadems worn by Angkor royalty as far back as the 9th century. Other items were also treasured legacies of Cambodia’s past: belts and necklaces woven from fine gold filaments, or body ornaments shaped into rosettes and scrolling vines.

9 New Jewelry Books That Really Shine
Recommended by
only Natural Diamonds

Thanks to these new titles celebrating style, history and natural diamonds, 2023 is off to a bright start.

In the afterglow of the holiday season, we’re looking to find a bit of sparkle anywhere we can. Luckily, our favorite publishers are here to jazz things up with their latest offerings. In addition to the newest jewelry designer monographs — those on Boghossian, Dickson Yewn, and Patania top our list — there are plenty of titles worth pouring over, including a newly reprinted tome dedicated solely to the existence of tiaras. Cartier’s latest nature-inspired collection is also celebrated in a new volume, as is Louis Vuitton’s Tambour watch, which turns 20 this year. Other standouts include an exploration of adornment in Chinese culture, an in-depth analysis of hip hop style (nameplates and oversized hoop earrings, included) — and a historical examination of the red carpet that yields tons of photos of Hollywood stars dripping in diamonds; need we say more? Below, 9 new jewelry books for 2023 that you won’t want to miss.
