"FACETS concludes as most successful exhibition in its 30-year history!" exclaimed the newspaper headlines.

With 70 exhibitors, 5,000 visitors, and 100 very serious buyers from 20 different countries, the 2023 FACETS gem & jewellery show was a huge success!

Altaf Iqbal, chairman of FACETS Sri Lanka, told the Daily News Sri Lanka, "The industry showed extreme courage when it decided to organize the exhibition, making it the first international event in Sri Lanka post crises, showcasing the island is safe and very open for business as usual." 

If you recall, the last FACETS show was in 2019. "Due to Covid, and the economic recession, we did not produce the show in 2020, 2021 or 2022," says Roshen Weereratne, Head of Projects for FACETS. "This time it was a smaller show, but it was a premier show in a five star Hotel - the Cinnamon Grand, Colombo."

It's Just Business

Sarine Signs MOU to Acquire Majority Stake in GCAL

Sarine, the leading manufacturer of artificial intelligence measuring devices for the gemstone industry, has just signed an MOU (Memo of Understanding) with GCAL (Gem Certification and Assurance Lab)

Sarine Technologies Limited is an Israel-based Company engaged in developing, manufacturing, marketing and selling precision technology products for processing of diamonds and gemstones.

The Company's products provide solutions for every stage of rough diamond manufacturing process from geometrical modelling and internal inclusion mapping of the rough stone, through determining the derivable polished gems, based on true dollar value, through laser cutting and shaping.

The Company's DiaMension family of products, including the DiaMension HD (high definition), are used in gemological institutes for the qualification and grading of a polished diamond's proportions.

New AGTA Committee
to Standardize Industry Terms Surrounding Sustainability & Ethics
January 18, 2023

(Dallas – Jan. 18, 2023) – The AGTA has unveiled a new member committee to define and standardize contemporary industry terms such as sustainability, ethics, and responsible sourcing.

A rising interest among consumers in supporting ethical-minded businesses, including ones whose products and services benefit the environment, offer fair pay, and are mindful of sustainability, is driving an increased use of contemporary terms that lack uniform definitions.

The goal of AGTA’s new committee is to develop verbiage that is practical and specific to the colored gemstone and cultured Pearl industries. The timing of this committee dovetails with the Federal Trade Commission’s (FTC) call for comments surrounding another update to its Green Guides (click here to learn more). AGTA will work with the Jewelers Vigilance Committee to develop sound proposed revisions and additions for the FTC.

“AGTA was a pioneer in establishing guidelines for the jewelry industry to follow surrounding ethics, transparency, and sustainability,” says John W. Ford Sr., CEO. “We look forward to this opportunity to further clarify specific terms and consumer interpretations of them.”

The mission of the new committee is as follows. ...

They say that there is smuggling. But the complaint is not about smuggling. The complaint is that there are "rumors" of smuggling, and these rumors are hurting business.

These days, it’s also a mecca to well over a million visitors each year, most of whom converge on this small town in a wave of RVs during the months of January and February.

During the winter months, 2,000 vendors of rocks, gems, minerals, fossils and everything else imaginable create one of the world’s largest open air flea markets in Quartzsite, AZ. Eight major gem and mineral shows in addition to vendors of raw and handcrafted merchandise peddle their wares to snowbirds, collectors and enthusiasts, making Quartzsite, AZ the place to be in January and February.

STF raided ‘gemstone’ to be sent to NGJA for appraisal

Do you have time to have a little fun? What do you think it is? Send us your best (or worst) guess. We will wait for the results of the lab and then reveal the best (and worst) guesses here! (We will disguise the names of those who wish to remain anonymous.)

So here's the story....

The red coloured gemstone (posted here) taken into custody by the STF at Medawachchiya last week, has been referred to the National Gem and Jewellery Authority (NGJA) to get its genuineness verified, police said.

The STF officers of the Kebithigollewa camp had conducted this raid on December 2 and had arrested two suspects while they were attempting to sell this stone to a businessman for several millions.

from Gemworld International: Fire Opal

Çiğdem Lüle, PhD, FGA, GIA GG, DGA

Opal is classified as a “mineraloid” or mineral-like in scientific terms. It is a silica-gel made out of microscopic spheres with water molecules in between, therefore an amorphous material. While opal is a widespread material on earth’s crust, gem quality opal is quite rare.

Precious opal has a more regular structure compared to common opal. Tiny little silica gel spheres in its structure are of similar size and create the unique phenomenon known as “play of color.”

Opal has been a popular gemstone for thousands of years despite its low durability. Ancient Romans called it “opalus” literally meaning “precious stone.”

You Need a Ruby Chandelier, Yes?

You Need a Ruby Chandelier, Yes?

Okay … you definitely do not see one of these every day. Called “the Roses” chandelier, it is set with 65,040 carats of ruby, 12.07 carats of diamond, measuring approximately 8 feet tall by 3 feet wide, and weighs approximately 50 kilos! (… over 100 pounds!)

We saw this on LinkedIn, with Vikas Dugar of RCS Gems / Real Gems Co. HK Ltd., standing beside the chandelier. “It’s one of a kind,” says Vivek Dugar. A collector’s choice ruby chandelier. “It took almost 3 years to sort and prepare with keeping small and tiny handwork done very carefully. All handcrafted. There are 65,000 carats of natural rubies, with diamond, silver and gold.”
