Frequently Asked Questions
Q. After I get my sapphire sand in what is the easiest and cheapest method to use to screen and look for them? Also after I have found them what is the next step - can I run them in a rock tumbler? or use a cutting tool? A. You can use a kitchen sieve and wash a cup of gravel then spread it out on a glass pie dish. Put a light source underneath - flashlight or lamp or use a slide table. Once you find the sapphires - they are glassy in appearance- send them in to be faceted, using the coupon sent with your order. You can also print another one from our website under "Faceting Services" at www.sapphiremine.com A rock tumbler is great for the rocks, agates and minerals you find - however, it will decrease the value of the sapphires. Sapphires should be worth $100 per carat faceted versus .10 cents when tumbled. Q. Hello, My Husband and I are new to the idea of mining. We were wondering how much is charged for Faceting once you find something in one of your bags or box's? Also, I was wondering what winter gravel is as compared to just the gravel? A. The faceting prices are on the back of the coupon. They run about $7 a finished carat for sapphires. You can print another coupon from our site at www.sapphiremine.com under "Faceting Services". Scoll to the bottom of the page and print. The "Winter Garnet Gravel" is just garnet material from a different mine. We named it Winter a couple years ago when it was snowing and we were depressed. The sparkly garnets seemed to cheer us up. The other gravel is mined here at the Spokane Bar Sapphire Mine plus our other mine the Ed Dorado. Q. I am just wondering how I might be able to actually get the sapphires out of gravel? Do we require a rock crusher or some specialized equipment? Can I hit it with with a hammer? I am just asking because I would have absolutely no idea how to even look for or recognise a sapphire in gravel. Any tips would be very much appreciated.
A. There is a direction card clipped to the
flyer. If lost, you can print one under "Print Flyers"-"Directions" at
www.sapphiremine.cm. It helps
to wash a cup or so at a time using a kitchen strainer or screen. You can
spread the gravel on a plate or better to use a clear glass pyrex pie dish
with a light source underneath. The light will shine through the gems and not
the rocks. You can either use a light table made for slides or use a flash
light under the dish. You can also cut out an old metal coffee can, mount a
light bulb in it, and put a piece of glass or a pie dish over it and pour some
gravel in. Direct sunlight outside is also good to search for the sapphires.
Gold nuggets can at times be found as well as unusual minerals such as topaz.
The rocks in outdoor sunlight will appear in varied colors - green is often
serpentine, dark green is olivine, at times jade can be found. Also found -
jasper-reddish, lots of quartz, and agate-waxy. Shale will be sharp - not
water-worn like most of the gravel. If you hit any of the sapphires with a
hammer you will ruin them. Sapphires will often have a hexagonal crystal
structure. A clear sapphire the size of a mustard seed can be about 1/3 to
1/2 carat and have a finished value of $20-$50 bucks. Clear and colorful
sapphires larger than a pea can have a finished value of $100-$1000 bucks.Look

Q. I read a testimonial mentioning a Light Box for sorting. Can you please send info on buying, building, proper use of such.
A. You can buy a light table from Logan
Electric Specialty Mgf. Co in Chicago, IL, 60622, model 920. Pricey though.
Try Walmart or a photo shop for a slide table for photographs. We use light
tables to help pick out the sapphires. Light will shine through the sapphires
and garnets but not the rocks. You could miss gold nuggets on a light table,
however.
Q. What is the process you go through to get the sapphire gravel?
A. The material has to be processed. The
gravel dug from the Spokane Bar is 20 feet deep. We must remove 15 plus feet
of overburden then dig the remaining gravel down as deep into the bedrock as
possible. Then we haul it out of the pit with dump trucks and stockpile the
gravel. Our trommel is started, pumping water over 100 feet up from the
lake. The gravel gets sorted through the trommel, taking out the boulders,
sand and sizing the material. It then goes into another machine, called a
jig. That machine separates the gravel by specific gravity. The heavy
material is then hauled into the office and sacked. (We try to dry it first)
It is quite a process. You would not want just raw material as you must
process through ten dump truck loads to get any sapphires. I wish they were
more plentiful but that is why they are valuable.
Hand digging is another matter. It still takes a lot of work to loosen the gravel (like digging into concrete), screen it - sorting out the boulders and sand, and then concentrating it by hand using double meshed screens in tubs of water. It is a slow process and again, not as rich as you would hope. The old saying "you can be an inch from a million dollars or a million inches from a dollar" applies. It only takes one good sapphire to make it pay, however, not like gold - which takes one level teaspoon to make an ounce (lots of flakes and specks). Q. When we use the coupon provided for gem
cutting, do the gem cutters A. Faceting will take away 2/3rd of the
stone plus more if the stone has Q. Are the "flakes" of "gold" in my
Garnet Gravel real or fools? Q. How do you tell the difference
between a garnet and a red sapphire? Q. I really enjoy screening my gems, but
need to know how to pick out which ones to send out to be faceted. We have
found several clear sapphires, as well as a couple of larger sapphires that
don't appear to be clear, but how would we know if the center area is more
clear? Q. I saw on your website that the stones
can be heat treated, can you give me your feeling on this? Q. we pay by the carload, for the stones found, per person? Do we need to rent buckets and shovels or may we bring our own? A. We advertise the gravel we sell in the office on our flyer which ranges between $25 and $75. We do have sample bags for $5 which is about a screenfull. Our dig option can be shared with the family. It is $60 total and includes one large concentrate plus digging a five gallon bucket in the mine. We provide screens and shovels - some buckets. It is wise to bring your own bucket in case you want to take material home. Also a screwdriver for digging into cracks and crevices if you do the dig. Tweezers are helpful - we do sell them for $3 in the shop. Q. I am curious about the value of the faceted sapphires - what do you sell them for in your shop? A. The value of the sapphires ranges from $100 a carat up to $1000 a carat. A half carat (.50) would be $50 as there are 100 points in a carat. Stones that finish over a carat can double in price or more. The four "C's" apply - color, carat weight, cut and clarity, as far as values go. Q. Regarding the E-Monster Mine...is there any difference in source or quality of gravel, or is the price difference based on the coupon for faceting? A. You can read about the different Monster Mines in my October 2003 and November 2003 newsletter at www.sapphiremine.com and click on "Newsletters". The E-Eldorado Monster Mine costs more due to the haul fees-40 miles on a bad road with big haul trucks. The El Dorado is new mining property we acquired last October. It is similar material. So far - I have noticed the El Dorado sapphires seem to be bigger. The Spokane Bar Monster Mine material seems to have more colors. El Dorado has a bit more debris- such as twigs and roots - as the gravel is only four feet deep compared to Spokane Bar - of 30 feet. Lots of people try both and compare. You can view some comments about the differences under "Testimonials". Q. I need to know how to pay you with a personal check....??. A. Personal checks and money orders can be mailed to: Spokane Bar Sapphire Mine/5360 Castles Road/Helena, MT 59602. We also take credit cards, debit cards, phone orders at 1-877-diggems, or on-line orders at www.sapphiremine.com The faceting coupon is a totally separate issue. You will need that to get your gems faceted at a very reasonable rate. Q. I'm getting ready to have the first sapphires faceted and have some questions about heat treatment. Most of the stones are quite pretty in their natural state and we will not want to heat them. But some of the duller colors (very pale greens, blues and almost clear) might be prettier heated. So...should this be done before or after faceting? Approximately what does it cost? And can you send me contact info for someone who does heat treatment? A. I would recommend heat treating prior to
faceting. Once treated the cutter will be able to orient the color better. If
you wait until after the stone is cut - it can still clean out the silk but
often the stone will need to be repolished - or recut and then loose some
weight. Elliott Sher, the facetor listed on our website, also will heat
treat if you ask him. It is under the "Faceting" link at
www.sapphiremine.com. |
