A NEWSLETTER FOR ROCKHOUNDS SINCE 1940
from Sue Moore
S o u t h e r n N e v a d a G e m & M i n e r a l S o c i e t y
What a great party!
For everyone who attended our Annual Awards Banquet, I hope you didnt go away hungry. What an awesome assortment of great food. Thank you to everyone who brought dishes to the dinner.
I know that for most of you, the remainder of this month, you will be involved in making and distributing gifts for friends and loved ones. There is still time to come up with lapidary based gifts. A great idea for beginners is to fashion a cabochon and attach it to a hat (a la Kidd Rock). The shop is warm and cozy and a great place to meet with and trade skills with your fellow rock hounds, so come on down!
The first order of business for the 2014 Board of Directors is to fill the Committee positions. If you are interested in being on or leading a Committee in 2014, please contact any Board member and throw your hat in the ring. One of the items that I would like to address is the feasibility of hosting a rock and gem show here in Las Vegas. The cost of using the big hotels and convention centers is prohibitive, but I would like to investigate other options, like school multipurpose rooms, VFW, American Legion rooms, or anything else that the research committee can come up with. We wont know until we develop a summary of the availability of various rental sites in the Valley. Boulder City should be considered also.
Next, we need to establish the 1st quarter field trips. We welcome all requests and suggestions. Bill and I will be going to Quartzsite for the Powwow, which is January 22nd through 26th, this year. The field trips provided by the Quartzsite Roadrunners are a lot of fun. I have been on most of them, so feel free to ask any questions regarding the trips. Bill and I have been camping in the privately owned area, which is at the west end of Main Street, just past the Revival Tent. The cost is $5.00/day, but the convenience is worth it. There are no bathrooms or water (you are dry camping), but the Loves across I-10 has bathrooms and showers.
Thank you for putting your faith in me as President. I look forward to an interesting and fun 2014 of rock-hounding, faceting, cabbing, silver-smithing, beading, wire wrapping and all of the rest of the skills that are available to our membership. Come join me.

HOW TO SHAPE AND
POLISH OPALS WITHOUT MACHINERY Via: Strata Gem, September 2010 Opal is a hydrated silica with varying amounts of moisture. Its hardness varies from 5.5 to 6.5. This method of cutting and polishing opal practically eliminates fracturing from heat. There are four basic steps in shaping and polishing: 1. Sanding off the matrix on both sides to locate the best fire. 2. Rough shaping the stone. 3. Sanding and pre-polishing, which result in the final shaping and size. 4. Final polishing the gemstone. SUPPLIES NEEDED 1. A carborundum stone, double grit, sold by most hardware stores. 2. Wet or dry sand paper, 400- and 600-grit 3. A piece of inner tube, 6" square. 4. Two pieces of corduroy or velvet material, 6" square. 5. Polishing agent, Tripoli or tin oxide 6. Aluminum pie pan 7. Dop stick and household glue or cement. INSTRUCTIONS: Place carborundum stone on the inner tube in the pan, course side up. Pour water on the stone until some stands on top. Always work opal on a very wet stone. With a circular motion, grind on both sides to reveal the best fires. Mark size of desired stone on the back of the opal and grind down to size. When size has been obtained, wash opal, carborundum stone, inner tube, and pan. Do this between each process. Now the opal is ready to be dopped. Use a cold dop of household cement. Coat the end of the dop stick. Also coat the back of the opal. Let it set a minute, and then press together. Stand in modeling clay or other support to dry, about eight hours. When the opal is set on the dop stick, use the coarse side of the carborundum to shape the opal. Wash all equipment. Then this time, using the fine side of the stone, sand out all the scratches, wash, and proceed. Go through this process first using the 400-, then the 600-sanding paper. The opal should have a pre-polish on it. For the final polish, use the same process with the tin oxide. A little Linde A may be added to the tin oxide if you wish. To remove the stone when finished, soak overnight in water and the stone will come loose. Good luck, and may you have a beautiful stone. Malachite, turquoise, chrysocolla, as well as many other stones under 6.5 hardness may be polished with this method.

Congratulations to James Sloan for winning the centerpiece contest. What a wonderful job and such beautiful work! Many hours went into carving this magnificent sculpture. It includes a variety of different stones and was hand carved. Its obvious that he put his heart into this creation.
