Saturday, Dec 7: Jewel Tunnel Imports OPEN WAREHOUSE SALE


We are having our annual Jewel Tunnel run again this year. There will be minerals from around the world, jewelry, geodes, carvings, bookends, and much more. These make great gifts so it's a great addition to your Christmas shopping.

Rock Currier, owner of Jewel Tunnel Imports will be opening the warehouse to Council members and guests. Refreshments are served throughout the day as you search Rock's endless shelves of rare treasures. Rock asks for your support of the Council by making a tax-deductible donation of 25% of the purchase price. That means that you will still be paying nearly 40% less than retail. (Sales tax will be charged unless you can provide a resale number.) Please plan to write two checks, one for your purchase and one for your donation to the Gem & Mineral Council. There is no admission charge for this event. Family and friends are welcome, but Rock asks that any children be closely supervised. There will be more than enough rocks and minerals for everyone, but plan on coming early to give yourself plenty of time to go through Rock's vast stock. For more information, click here to see the flyer.

Saturday, January 17, 2015: An Evening at a Collector's Home


Our first meeting of 2015 will be kicking it off at our emeritus curator's home.

In addition, Tony Kampf will be giving a talk on fakes and frauds. Many mineral specimens (and indeed most gemstones) have been “doctored” in some way to improve their appearance and their salability. Unfortunately, the practice of “enhancement” is a slippery slope, sometimes leading to outright fakery and fraud. He will be looking into the critical and often humorous ways of the many different techniques for enhancing and faking mineral specimens (and some gems) and the clues to look for in detecting them.

By invite only.

For any additional information about these events, please contact the Gem & Mineral Council at or (213) 763-3326.
