You can also cut Black Tourmaline (schorl). It makes very nice stones.
We have cut cabs out of it. I haven't faceted any.

In reply to Todd's question about solid black rough.
I have just had exactly the same enquiry (eerie huh!!!!) and have decided to
do it in spinel. It is easy to cut, polishes well and is DIRT cheap!
Quick too when you only have to cut the crowns.
After cutting the crown I am transferring the stone using my transfer jig
and then cutting a flat pavilion at 0 degrees (as for a table) just as if it
were a cab. Not forgetting to chamfer the edge on the pav side at 45
degrees to avoid chipping. Best not to polish the bottom of the stone as
you can then use epoxy or such to fix it in the finding.
Lady in question asked me to just cut a stone for a ring, which I did in
checker board pattern round. Then she finally finds the antique necklace
and earrings which have OVAL stones and wants it to match. No probs! Since
the spinel cost me $0!!!!! Its all good practice!!!!!!

We have plenty of schorl tourmaline in Maine but let it be known that less
than 1 percent of that may be cabbing or facet grade..Good hard schorl is
not easy to come by. My son and I got into some pocket schorl 2 weeks ago
at Mt.Apatite .Aurburn Maine... First hard stuff I found there in 4
years....When I cut it all the water turned dark blue.......Well you see now
all that looks black might not be black....It is wonderful stuff to work
with and takes a great polish...I have purchased some beautiful completely
terminated schorl crystals from Brazil........now these are really hard and

You should probably do well in faceting the black (schorl)
tourmaline. It seems to be in fashion here in Brasil and we
have seen a lot of jewelry made with it, in faceted stones.
You will probably use the same laps and powders etc. that
you would use for green tourmaline. At least here in Brasil
- nothing is changed due to the color of the tourmaline.
You may have to experiment a bit with the black tourmaline
as there are varieties that don't facet well and 'crumble'.
The variety that is usually faceted here in Brasil is
called 'quebra lisa' (smooth break).
We have made up fancy shaped cabochons out of the 'quebra lisa'
tourmaline and tried the USA market - but the jewelers seemed
to not appreciate the difference from dyed black onyx as the
price of the tourmaline was a good bit more - but it does take
a very nice polish.
At the recent shows in Brasil we saw several people doing
carvings in the 'quebra lisa' tourmaline also. Mostly animals
and fish. And of course there is the metaphysical aspect of
it - which is supposed to be good for something or other
(I think it prevents migraine headaches - or at least that
was the reason my wife wanted a naturally terminated crystal)

Maybe try black diopside? New Era Gems (www.neweragems.com) has this
material and looks like it has potential. No experience with it personally,
just noticed it and thought I'd pass it along.
Best of luck, Carol

I seem to recall that one of either Paul DeSautels' or Joel Arem's
books or my old GIA Colored Stone textbook (all of which, granted, more than
a quarter-century old, at this point), defined the word, "Gem" as being any
object which possessed beauty, rarity and durability (the latter of which I
interpret to mean "sufficient durability to enable frequent wear"). Even
after all these years, I've yet to read or hear a better definition. The
neat thing about this definition -- or, at least, my interpretation of it --
is that it permits me to feel good about applying it to such untraditional,
yet perfectly wearable goodies as the
Asteriated-Rose-Quartz-over-Agatized-Pyrite doublets I sometimes assemble,
which are every bit as rare and durable, and considerably more attractive
than many of the so-called "traditional gems" I've seen in dealers' cases,
through the years!
Maybe that's part of the deal, Gerr': interpretation of that which is
beautiful, or rare, or durable. After all how much rarer would Diamonds be
than fine Amethysts, if neither's markets were artificially controlled by
suppliers? And which would be more durable, a $250,000.00 Diamond or a $4.00
slab of mutton fat Jadeite, if the two were suddenly smacked against one
another in a cold room? Perhaps the old adage about beauty being in the eye
of the beholder lends more than an inkling of insight into the quandary of
arriving at a more concise definition. When you stop to think about it,
since beauty, rarity and durability are all very relative properties -- that
is, not even one of them can ever stand alone as a purely "factual"
adjective of anything, save for by comparison to other items -- it makes
sense to question the validity of a hard-and-fast definition or three, every
now and then. If and when you manage to arrive at one you feel comfortable
with, please take a moment to email the list again, and share it. Until

specifications, maintenance cost,spares, etc.of these tools. Do any of your

using and maintaining a ultrasonic drill. Does any one recommend or had
experience with a particular manufacture hardware.
We cut custom cabs and beads, we are looking for a fast , easy way to make
holes in hard material.
Any comments, info, or advice would be appreciated greatly, as I'm stumbling

i have been reading old mining tales and i wanted to share a factoid
from one of the stories. these stories originated in the early 1900's
when all the good stuff was being mined. it seems when cut garnets were
sold, they were salted with "breweryite!" does anybody recollect what
well, seems that the brown beer bottles where about the same exact color
as some of the garnets that were being cut and sold and so, the parcel
was salted with cut brown glass!
Hi Patty, I have breweryite in black, golden brown, green and even red. LOL

Subject: Rock Polisher
I have been on a quest to find a source to purchase a
polishing kit to use on a large collection of Petoskey
stones that I have accumlated over the years. So far,
I haven't had any luck. Your web site was suggested
and since you have an e-mail address, I thought I'd
write to you.
Can you suggest a catalog, or other source, that might
have the equipment I would like. My father had a
small electric tumbler/polisher many years ago and I
thought finding one would be easy!! Any information
you may have, would be appreciated. Also, if you
don't know of any source, or don't believe there is
one, let me know and I'll discontinue my search.

Catching the Bear
Two men went bear hunting. While one stayed in the
cabin, the other went out looking for a bear. He soon
found a huge bear, shot at it but only wounded it.
The enraged bear charged toward him, he dropped his
rifle and started running for the cabin as fast as he could.
He ran pretty fast but the bear was just a little faster and
gained on him with every step. Just as he reached the
open cabin door, he tripped and fell flat.
Too close behind to stop, the bear tripped over him and
went rolling into the cabin.
The man jumped up, closed the cabin door and yelled
to his friend inside, "You skin this one while I go and get
