Don't miss our meeting on the 2nd, we have a great program panned with a world class gem carver presenting her tips and techniques and showing some of her work which will also be available at our show for purchase.

Come prepared to learn, and to sign up for one of the many jobs that need a hand, and also to sign up for the setup meal that we will be hosting for the dealers on Friday the 5th at 6 pm. See you at the meeting!

Interesting Emerald Facts:

Emerald is the most precious stone in the beryl group
. The name comes from the old French word 'esmeralde', which was derived from the Greek word 'smaragdos' meaning 'green stone'. By definition, emerald is any medium to dark green beryl colored by chromium. Green beryl colored only by vanadium is not considered to be true emerald, but rather as simply green beryl. Since the 1960s, the American jewelry industry changed the definition to include vanadium colored beryl as 'emerald', but in the UK and Europe, they are still not recognized as such.

Tips of the Trade
When cutting sheet metal, it's quicker and easier to use a set of shop shears as compared with using a hand saw. The cut is not as precise, but many times you don't need that. Shears will easily cut up to 24 gauge sheet, and some will cut 22 or even 20 gauge.
Current prices for shears run from $13 - $22 in jewelry catalogs, and the Joyce Chen scissors recommended on some jewelry blogs run more than $20. But we found a cheaper alternative at the 99 Cent Store - some gardening utility scissors that were only $1.07 I buy a half dozen of them at a time for use in my jewelry classes.

They're great for cutting bezels, trimming around a bezel cup and cutting a piece off a larger sheet.  

Notable Gems

The Chalk Emerald is a 37.82 carats Colombian emerald. 

The royal rulers of Baroda State in India once owned the emerald. It was the centerpiece of an emerald and diamond necklace worn by the Maharani Saheba, who passed it down to her son, the Maharajah Cooch Behar.

In the 20th century, the emerald was recut from its original weight of 38.40 carats and set in a ring designed by Harry Winston, Inc., where it is surrounded by sixty pear-shaped diamonds, totaling approximately 15 carats (3.0 g). The ring was donated by Mr. and Mrs. O. Roy Chalk to the Smithsonian Natural History Museum in 1972 and is part of the Smithsonian's National Gem and Mineral Collection.

The Mackay Emerald Necklace

The stunning 167.97-carat Mackay Emerald was mined in Muzo, Colombia. The largest cut emerald in the National Gem Collection, it is set in an Art Deco diamond and platinum necklace designed by Cartier Inc. In 1931, Clarence H. Mackay presented the necklace as a wedding gift to his wife, Anna Case, a prima donna of the New York Metropolitan Opera from 1909 to 1920. The piece was donated to the Smithsonian Institute by Mrs. Anna Case Mackay in 1984. Source: The National Gem Collection by Jeffrey E. Post.

The rules for the JALAF are:
Participants will remain beginners for one year from the month in which they enter their first piece in each category. At the end of one year the participant will be considered experienced in the categories they have entered. The JALAF master will attempt to keep records, but we will operate on an honor system as well.

We want to share and learn from the knowledge you acquired while finding, working or setting the piece, so please come prepared to tell us what you know (don’t worry if you don’t know what you have, hopefully someone can tell you)! The JALAF is open to Members, Juniors and Visitors.

We REALLY WANT and STRONGLY encourage ALL to bring pieces that fit the month’s theme, even if they are not eligible for entry because they do not meet the criteria or have previously won a feather. These pieces will be entered as display only, and will not be part of that month’s competition. PLEASE share your expertise and adventures with the rest of us.


Two levels in each category:

Specimens and Fossils: YOU must have found OR worked an otherwise acquired specimen.
Cabochons, Carvings and Facets: YOU must have created the piece yourself.
Jewelry: YOU must have created the setting OR worked the stone.

Since some months have more than one birthstone, we will be going by the American Gem Society list, found at:

Here is hoping everyone will compete and have fun!

See you at the next meeting!
