#1.) again ... Curious Details of GIA's Layoffs

An overwhelming response to this feature article for two weeks in a row.

Was it simply because of the industry slowdown, or is the rumor about AI true?

We asked, and here is GIA's response.

2.) Sotheby's Hong Kong: Magnificent?

What an eye-opener! Of the first fifty lots with the highest selling estimates, over half went unsold! And of the remainder, six hammered at less than low estimate while only a small handful reached the highest.

That said, there really were some magnificent jewels.

3.) Le goût Rothschild
Defining the Dynasty’s Legendary Style

Since the 1700s, the family name Rothschild has been synonymous with world-class wealth and taste. The banking family fortune has placed them into an unreachable wealth, some estimate at one Trillion dollars.

To live like the Rothschilds may be completely out of reach, but you may be able to at least own a piece of the family wealth.

Lotus Gemology - Gem Science/Plate Tectonics is one big reason
Sapphire Origin, Sri Lanka or Madagascar? Answer: It's Gondwana's fault! (pun intended)
Sri Lanka or Madagascar?

Lotus Gemology

Did you ever wonder why some blue sapphires get a Sri Lankan origin from one laboratory and a Madagascar origin from another?

One reason has to do with the science of plate tectonics... how the continents, once attached to each other, are now separated by an ocean!

Did you ever look at a globe and wonder if Africa was ever once attached to South America? They were! But now there's an ocean between. This is the result of plate tectonics.

And believe it or not, Sri Lanka, India, and Madagascar were all once attached, sharing a mineralogical belt full of gem formations where we now find sapphires.

Lotus Gemology has a great short feature for you here that explains why sometimes one lab will issue a Sri Lankan origin while another lab will issue a Madagascar origin for the same blue sapphire.

In a recent LinkedIn post, Samantha Lekkas, Executive Vice President of Sales and Merchandising, voiced support the concept of a Free Marketplace of Ideas by pointing to Pandora and their recent move to have Pamela Anderson as their spokesperson.


"Pandora’s latest move of getting Pamela Anderson to be the face of Lab Grown Diamond is a checkmate and here’s why… Think back to the Baywatch version of Pamela Anderson with the fake long bleached hair extensions, loads of makeup, fake tan, fake nails, fake eyelashes and fake ...

Mining: Sodalite from Malawi
Sodalite from Malawi: a New Discovery
Lapis' little sister
Gary Roskin
Roskin Gem News Report

Kilometers of Sodalite up Mulanje Mountain

When one thinks of the classic gem materials, Sodalite unfortunately is not one of them. In fact, you could probably name off dozens of gems before you get to Sodalite.

And yet, it is a beautiful material, similar in appearance to, and often confused with, Lapis.

Not surprisingly, it has taken a back seat to Lapis it's entire history. So it shouldn't come as a surprise that the last time it was written up in the Journal of Gemmology was back in 1979, Volume 16, Issue 7 (1979) - The blue colour of sodalite, or in a 1990 Gem Note, Gems & Gemology, Unusual gem quality sodalite.

But now thanks to a discovery of kilometers of material in Malawi, this may all change.

The new Malawi Sodalite discovery lies in the field moving up Mulanje mountain. According to prospector Alfred Noah, “The mine is really in the same area as that of Mulanje Massif, a very nice tourism area.” Hiking trails, with waterfalls attract campers from neighboring areas. “The concession is huge,” says Noah, “covering almost 50 square km, with various sodalite outcroppings. Right now, we are only focusing on one outcrop.”
