PrettyRock.com : Faceter's Gallery
Hello,
Just want to remind everyone that we have a Faceter's Gallery. This is a free way for all faceters to market their services or just a way to show off what you do.
This is ONLY open to faceters who do their own cutting.
http://www.prettyrock.com/faceters-gallery.htm
If you are interested in being included please email me the following:
1. Name and location (city and state is fine) and pretty picture of you (or your cat or grandkids or studio)
2. Do you accept commissions? (You don't have to to be included.)
3. Short (very short ) bio of your life as a faceter.
4. Contact info: email or address or phone Please remember this will be on the internet. Sorry, I am not going to act as a go between
5. Images of stones you have cut, about 200 x 200 dpi, .jpg format. We are limiting the gallery to 3 images of your choice of stones. However, you can post as many as you like if the rough is purchased from us These are not images of items for sale, we aren't putting up prices. They are examples of what your work looks like, you don't have to have the stone still in your possession.
We have thought about having a Jewelry Gallery, too. If you would be interested, let me know.

Carving Tutorial by Hans Meevis
http://www.ganoksin.com/borisat/nenam/freeform-gem-carving.htm
He does a great job of going step by step through the process with photos of the tools and stones along the way.

Marketing Handcrafted Jewelry and Gems
PrettyRock has a bit of a different business model, we are selling the materials artists use as opposed to art itself. But we do spend a good bit of time and energy (and money) marketing with advertisments on the net and in magazines, with the blog and links. We did shows for a long time, but although they were fun and a great way to meet people, they turned out not to be cost affective in terms of marketing.
What have you found to be affective? Participate in shows? Do you have a website? blog? do you advertise on the internet or in magazines?
If you are looking for ideas, ganoskin has great section of articles:
http://www.ganoksin.com/borisat/directory/library/subject/11/1
If you find one you really like, please share the link.
This is a marketing audit directed at jewelry makers:

Great way to get you brainstorming.
I'd love to hear your suggestions!

Andesine: the Cliff Notes

Pala International has published a good article that summarizes the whole andesine issue. http://www.palagems.com/gem_news_2008_v3.htm#andesine
Since there was never really any rough available to the rough dealers, Dev and I have not been personally involved in this issue. I think we bought one cut stone a year or two ago, just to see what all the hoopla was about. Since at the moment, we are a rock shop and not a lab, nor an investor in andesine, we promptly stuck it in a box marked "To be identified later" and forgot about it.
It has been very educational to see how this story has unfolded, how the different gem labs and researchers have evaluated the gems and come to conclusions (or not), and all the actions and reactions of the different sides involved. It has been a very emotional issue for some, and source of investigative detective work for others. We can only hope for those who have collected many stones, that either it turns out that there is real andesine, or that the companies they did business with will do the right thing and offer a refund.
I do think the andesine issue brought to the forefront just how influential the internet has become in gemology. On the positive side, scientists and gemologists are able to share their findings quickly, and information gets to the public more quickly. On the down side, we expect answers and we expect them now. It's hard to remember that good science takes time.

Light Sensitive Minerals

There is a great article in the November 2008 Rock & Gem Magazine, "Light-Sensitive Minerals: Why Some Specimens Lose Their Color" by Bob Jones. He discusses the chemical make up that creates the light sensitivity and how to care for and display light sensitive minerals. Some of the minerals he lists are:
Brown Zircon
Aragonite
Halite
Celestine (Blue)
Yellow Sapphire
Green Spodumene
Colored Diamonds
Smoky, Rose, Amethyst Quartz
Pink, Yellow, and Blue Fluorite
Red Spinel
Maxixe Emerald
Brown, Sherry, and Blue Topaz
And there are more.
It's very well done article, check it out if you haven't yet!

Specific Gravity Kit - Review from IGS
Dev and I were thrilled to receive the following review about our specific gravity travel kit.
____________________________________________________________________
PrettyRock.com has released a new Specific Gravity Travel Kit. This is a wonderful kit with a lot going for it.
My first impression was the high quality of the pieces and how well thought out it is. First, there is a very nice scale. It is small, to go with the theme of being light and portable. However, it also comes with a built in breeze cover and measures up to 100 carats. That is as much as any portable scale will handle. PrettyRock advertises that it is good through 50 carats. That shows their modesty and conservative attitude when it comes to advertising.
The kit comes with a small, plastic cube, the lid of which serves as the water vessel for the specific gravity readings. It is also used to store the hanging aparatus and the calibration weight. In addition, it comes with a sturdy little stand, a pair of tweezers and an electronic calculator.
Now, I like sturdy, but I was surprised at how heavy the weighing aparatus is. I had assumed that it had to be light, so as not to use up much of the scale's capacity. To test it, I weighed several large stones and even the calibration weight. Once the scale is zeroed with the weighing accessory on it, it retains its accuracy to the full 100 carats.
I was impressed. I have been using a wimpy wire for SG readings - one that causes me to use my full vocabulary. This set up is much easier to use and takes a lot of the headaches, and vocal exclamations, out of taking specific gravity readings.
Specific gravity readings are still tricky and a lot of care needs to be used. (See Specific Gravity Testing.) I wouldn't recommend using toluene in the plastic vessel. If you are interested in traveling with the kit, a small bottle of distilled water with a drop of liquid soap will both do the job and is safer.
This is a wonderfully easy kit to use, plus it is small enough to fit in your briefcase. Whether you are looking for something portable or something for your lab, I highly recommend this kit.
Sincerely,Donald Clark CSM IMGPresident

http://www.prettyrock.com/php/gem-id-database-BETA.htm
This is the beta version (for non-geeks that means we are still testing it) We would love for you all to try it out, see if you can break it, see what is missing, what's confusing, what you would like that isn't there, and so forth and so on.
If you break it, you do need to tell us [b]exactly[/b] how you broke it, or we won't be able to fix it. (We being Dev.)
Right now it has about 150 types of stones in the database. If you have one you think we should add, let us know.
This will be available free to use by anyone.
Dev has some weird addiction to making databases...can't get enough at work, so comes home and makes them here, too. He thinks it's fun \:D/ Not sure how he will entertain himself now that this one is done...

Prettyrock.com: Joe's Special Polish, and Joe's Opal Cure
We are happy add two new products to our store: Joe's Special Polish and Joe's Opal Cure. Created by Joe Depietrio of Bead n' More.
Joe's Special Polish is a secret blend of 3 different powders. It should be used on stones no harder than Topaz (8 on Mohs). It gives a beautiful final polish to cabochon, or faceted stones - especially opal.
The Opal Cure is a kit for curing opals that maybe be fragile or crazed. It contains Resin, Hot Stuff glue, and no stick plastic sheet, and directions use. It requires a heating unit, but Joe has included breif directions for creating your own in expensive heating unit using recycled items and items easily found at hardware stores.
Dev and I first used Joe's Special Polish ad Opal Cure in the opal class Joe was teaching at William Holland. We loved the results! He was kind enough to let us share his secret polish with our customers. Thank you, Joe!

PrettyRock Blog: Back from Rock Camp

We are back from our rock trip, and back to the daily grind..so to speak :) We went up a day early and went to the Franklin Rock and Gem show. I got a few cab to use in silver class and we ended up with some fantastic opals... not sure if we will be sharing those on the website or not, hard to let them go! This is actually several shows together, the Annual Macon County Gemboree, G & LW Wholesale Gem Show at Watauga Festival Center, another show that I am not even sure has a name, and then there is a little one across the street from the Gemboree. You do need a wholesale license to get into the G& LW show, so bring your papers with you if you go to that one next year.
William Holland was fantastic as always. This was our 3rd time there and it gets better each time we go. We meet so many new rock friends and see familiar faces, it's like home away from home. Dev took faceting and learned some new techniques and tips. I took Silver 1 and had a fantastic teacher, Will Smith. He has some of the most beautiful Tennessee Agate on his website: http://www.tnagate.com/ He also teaches faceting in Nashville for those of you lucky enough to live near there. I started the week sure I would set something on fire with the torch, but by the end of the week, I was using it like an old pro. Which is saying something for someone who doesn't even like to light candles. We made several projects, and I got to use some of the opal I cut in the opal class last time. (See top image)
On the way home, we stopped by the Grassy Creek show in Spruce Pine. It was a hot and steamy day, but we still rummaged our way through an entire bucket of Mexican fire opal looking for facetable pieces. There are two shows at Spruce Pine, the indoor North Carolina Mineral & Gem Festival and the outdoor Grassy Creek Gem and Mineral Show (sponsored by the Volunteer Fire Department, which I think it pretty cool.) We just had time for the outdoor one this year, but both are great shows.
