From a free seminar that explores recent gemological discoveries and research to an exquisite collection of musical instruments carved from gem materials, GIA’s offerings at the 2015 Tucson shows will enhance the visitor experience. The Institute’s participation at the shows – which also includes a show service laboratory, lab class, two fee-based seminars, library exhibit and the GIA Alumni Association’s annual event – will be at the Tucson Convention Center during the American Gem Trade Association (AGTA) GemFair™, Feb. 3-8, and the Tucson Gem and Mineral Show, Feb. 12-15.

GIA’s highlights at the 2015 Tucson shows include:

GIA Museum Exhibit
GIA’s museum exhibit “Symphony in Gemstones” will bring music to the eyes at the Tucson Gem and Mineral Show, Feb. 12-15. Twenty one pieces commissioned by Art Sexauer, GIA museum benefactor, and hand-carved by master carver Lothar Hermann of Idar-Oberstein, Germany, make up an exquisite collection of musical instruments in gem materials and 14K yellow gold. Featured are tourmaline violins, a Persian turquoise trumpet, lapis saxophone, a tiger’s-eye harp and a black onyx grand piano with a white quartz keyboard and a rose quartz tuba.

GIA Library Exhibit
GIA’s library will feature two of its rarest books at the Tucson Gem and Mineral Show, Feb. 12-15: James Sowerby’s “British Mineralogy” and Martha Proby’s one-of-a-kind “British Mineralogy after James Sowerby.” A mineral specimen, aragonite, which is featured in both books, will be on view courtesy of The Natural History Museum in London. The case will also include photographs and a map.

GIA Show Service Laboratory at AGTA GemFair
Show attendees will have convenient access to gem identification and country-of-origin services through the GIA Show Service Laboratory. GIA will accept gemstones onsite at the AGTA GemFair in the Onyx Suite Monday through Saturday, Feb. 2-7 from 9 a.m. to 5p.m.; and Sunday, Feb. 8 from 9 a.m. to 12 p.m.

Free GIA Seminar
On Friday, Feb. 6 from 9 to 10 a.m., GIA’s Distinguished Research Fellow Dr. James Shigley will provide a free seminar on “The Latest News from GIA Research.” This will include an update on the Institute’s latest research on diamonds, colored stones and other timely topics of interest.

GIA Education
GIA will offer one fee-based lab class and two fee-based seminars during the AGTA GemFair™. Pre-registration is required; call GIA admissions at (800) 421 7250 ext. 4001 to register for the seminars, and visit GIA’s website to register for the lab.

Diamond Grading Lab Class
Monday through Friday, Feb. 2-6, 9 a.m. to 5 p.m.
The lab class will teach how to grade diamonds consistently and accurately using a modern gem microscope and a jeweler’s loupe. Participants study GIA’s Diamond Grading System; explore time-saving shortcuts to determine a variety of grading factors; and are introduced to methods for reading a GIA Diamond Grading Report. Participants must pass a two-stone practical test to complete the class successfully.

Identifying Heat Treatment of Corundum
Saturday, Feb. 7, 9 to 11 a.m.
Participants will discover why corundum is heat-treated, and how different forms of heat treatment can alter ruby and sapphire. The seminar, which includes a lecture and hands-on lab component, will teach the identifying characteristics of heated and unheated corundum, and how low-temperature heat treatment and differences in corundum types can lead to complications during the identification process.

Identifying Glass Fillings and "Healed Fissures” in Corundum
Saturday, Feb. 7, 1 to 3 p.m.
High-lead-content glass fillings are currently the most common treatment found in ruby, while "healed fissures" are one of the most misunderstood ruby treatments on the market. In this seminar, comprised of lecture and a hands-on lab component, students learn the identifying characteristics of these treatments, why they are done, and to which types of corundum they are applied.

GIA at the CAD/CAM Pavilion
GIA’s  Jewelry Manufacturing Arts program is at the forefront of jewelry design education – from 3D printer rapid protoyping and casting to prefinishing, setting and buffing. Throughout the AGTA GemFair Tucson, GIA experts will answer questions and discuss a variety of relevant topics, including CAD/CAM, zero-shrinkage from CAD file to photopolymer models to rough castings, jewelry engineering priorities, jewelry design concepts, 3D scanning of gemstones and importing content into CAD files for use in making jewelry, and Quality Assurance Benchmarking criteria when CAD modeling. The ongoing series will take place in the AGTA CAD Design Studio, booth #450 in the Gem Hall.

Party at the GIA Gem Mine: Rocking Down Under
The GIA Alumni Association will “rock” Tucson during its annual auction, dinner and dance party on Friday, Feb. 6 from 6:30 to 11 p.m. at the Marriott University Park Hotel. Ticket prices are $55 prior to Jan. 15; $65 after and at the door. GIA alumni, students and industry friends can click here to purchase tickets.

#TucsonGemShow World’s Largest Faceted CSARITE® to be Displayed in Tucson

World’s Largest Faceted CSARITE® to be Displayed in Tucson

Milenyum Mining Limited is excited to announce that the world’s largest known faceted CSARITE® gemstone will be displayed by The Courtney Collection, Booth 2206 at the Gem and Jewelry Exchange trade show, 
February 3 – 8, 2015 in Tucson, AZ. 

The 121.65 carat pear shape rarity was cut from a rough of approximately 430 grams. Previously, the largest known faceted CSARITE® was an 88.49 carat pear shape that took home a coveted 2014 AGTA Cutting Edge Award.

“Achieving a faceted CSARITE® of this size and quality is extremely difficult, given the typical loss of rough when faceting,” stated Murat Akgun, president of Milenyum Mining Ltd, the operator of the world’s only CSARITE® mine. The only other large CSARITE® gemstones of a similar size have been cabochon gems that exhibit the cats eye and color change effect.

Erica Courtney of The Courtney Collection, exhibitor of the gem stated: “We are so excited to be able to share this one-of-a-kind color change gem with the industry! All the collectors and designers know that Tucson is THE place to find the truly unusual, so we expect to receive a lot of interest in this rare and responsibly-sourced stone.”

The lively gem is beautifully cut and exhibits a pronounced and vivid color change. It will be available to interested parties, along with calibrated goods and an extensive collection of fine-cut, larger single CSARITE® gemstones at The Courtney Collection, GJX Booth 2206.

MML is the world’s only source supply of CSARITE®, a natural, unenhanced color-change gemstone. Responsible for cutting and marketing of this phenomenal gemstone, MML’s mission is to introduce gem and jewelry connoisseurs around the globe to CSARITE®’s unique beauty and rarity. MML is a member of The International Colored Gemstone Association. For appointments to see this rare CSARITE® contact:

#TBT #TucsonGemShow 2014 Lecture Series at the Pueblo Gem & Mineral Show Part 2


In 2014 I was so busy with the introduction of two new shows that I wasn't able to get to the first two nights of the Lecture Series - but nothing was going to keep me from the last two.

I, and over 100 mineral enthusiasts braved the cool of the evening (there are heaters in the tent) because we were all looking forward to seeing the amazing Gail Copus Spann's talk...I think we were all just eager to see Gail following a very challenging year. 



“The Continuing Perspectives of A Woman Collector"

First up - Gail!

Gail talks on the thing she knows best - being a woman in the mineral collection world.  She is always so upbeat, straight forward and she engages the audience.

This night the tent was filled to capacity with at least another 20 people standing at the back.  
Everyone was excited to see Gail - she was greeted by John White and Dave Wilbur - quite the auspicious home coming...
She got right to the topic at hand.

SRO - it was a packed house!



“Celebrate 20 Years In Mineralogical Publishing”


Maury and Aisha introduced Ludmilla and Michael for a really fun overview of the first 20 years of the Mineralogical Almanac - with a little help from his friends,

Bob Jones (of Rock & Gem) briefly took the floor to add some great personal stories - the lecture closed with a traditional Bread Sharing Ceremony...

A BIG Thank You to Maury Destouet the General Manager of the Riverpark Inn and the Pueblo Gem & Mineral Show as well as the well connected and always polished Aisha Jan for assembling an amazing group of Experts for this Lecture Series.

From Aisha: "I have the honor and pleasure to select the guest speakers and to assist in the organization of these events. Our company Rocksaholics is a proud participant of this show." through to see who they have scheduled for 2015!

#TBT #TucsonGemShow 2014 Lecture Series at the Pueblo Gem & Mineral Show a Resounding Success!

I wasn't able to attend all of the lectures in 2014 - but the ones I did make were standing room only and chock full of great information...

I want to thank Maury Destouet the General Manager of the Pueblo Gem & Mineral Show and the always polished Aisha Jan for assembling an amazing group of Experts for this Lecture Series.

"I have the honor and pleasure to select the guest speakers and to assist in the organization of these events. Our company Rocksaholics is a proud participant of this show."

...and just wait until you hear who they have scheduled for 2015!

It seems that each year the Tucson Gem Show comes back stronger than the previous year...and 2014 was no exception.

The crowds are definitely returning (albeit with tighter budgets) but for the vendors that is all they need!  You can't look at row after row of amazing gems, minerals, home decor and jewelry without at some point figuring out a way to make the purchase!

The temptations and a definite uptick in business can be seen at the Pueblo Gem & Mineral Show - add to that this show is hands down in my top 3 MUST DO list and you have a recipe for a great day!

One of the things that is engaging shoppers at the Pueblo show is their Mineral Lecture Series...I know - lecture - ewww!  These are more like conversations with some of the most respected experts in the world!  I was able to attend two evenings of lectures....the Federicos and Gail Spann's comeback presentation!


“Mogok Myanmar (Burma): 
A secret overview of the most famous 
mining area for colored stones in the history of gems”



" Color Zoning in multicolored gem Tourmaline"

Shortly after booking this evening it soon became known as the Evening of the Federicos...the energy level at this event was through the roof!  The actual event was Pezzotta followed by Barlocher...of course if you know Federico Barlocher this will come as no surprise - who could follow him!?!


FB was fabulous with a video of the mining area - processing center - marketplace and many other views of an area which most people couldn't get in to see!  And here we were in the heart of the action!  

As much travelogue as mineral lecture - FB gave us a glimpse into the lives of the people of the region and a viewpoint from which to see how this operation works.  Of course it was all presented in FB's rollicking, whimsical look at life outside most of our comfort zones. 

If this interests you, follow Federico on YouTube, where you will see his amazing (non judgemental/non political) POV!


This may sound dry but if you have even the least interest in gemology or mineralogy you would have LOVED this presentation! Not at all dry and I went away truly understanding the theories presented.

The second Federico of the evening Federico Pezzotta's name may sound familiar to those who are constantly searching out the rare and unusual - the gemmy pink gem Pezzottaite is named after him!

"Pezzottaite is a caesium analogue of beryl, a silicate of caesium, beryllium, lithium and aluminium, with the chemical formula Cs(Be2Li)Al2Si6O18.  Named after Italian geologist and mineralogist  Federico Pezzotta, pezzottaite was first thought to be either red beryl or a new variety of beryl ("caesium beryl"); unlike actual beryl, however, pezzottaite contains lithium and crystallizes in the trigonal crystal system rather than the hexagonal system." Acording to Wikipedia

Without re-printing his entire talk this chart may give you an understanding of the theories presented - for more photos see the Photo Album on Facebook!

Next up Gail Copus Spann and The Mineralogical Almanac....
