Thank you to everyone who replied to my questions re Harts Range
I will play around with my camera using your tips and see if I can
produce some good quality shots.

> 2. ...photos of the rough what would faceters like to be able
Shoot photos of the rough sitting on a white piece of paper
under natural light (a bright but cloudy day works best) with nothing
more than the appropriate color balance for the conditions, using
decent digital camera. This gives a reasonable idea of the
the finished faceted stones. A photo or two of cut stones

It was nice to see questions on this subject. I purchased a 10 pound
vibrator on line and was a bit confused on useage. I played around
for a few
loads and came up with a few good observations.
I am only using this unit to do the first parts of the tumble process.
have also added ceramic tumble media to help grind down the rough.
I can put
down a load of quartz hardness stones in no time, oh also of course
added the silicon carbide. I do wash out the unit but save all the
silicon for further projects. Water level is important and you will
play with the level, I just watch the tumble and see how the stones
moving. I do know when I mix in too many pieces that are flat my
not do well. I have found stones of similar size and shape work
and speed the process a bit.
My final stages are done in smaller roller type units . Polishing
tumbler did not work well because the unit couild not be cleaned
not to have any left over abrasive from the rough grinds.
I will say that taking down the rough in the vibrator unit is soooo
faster . My polishing only takes a couple of days after I
beat them up good
in the vibrator.

Garnet abrasives have a long history in lapidary. Prior to WWII
were the only uniformly graded abrasive that was available commercially.
If carborundum was used, the user either graded it themselves by
elutriation, or it was only used for rough grinding. Garnet fines
typically sold graded by the actual grain size in microns; typically
avaliable grades available were 30, 28, 26, 24...,8, 6, 4. They
made from natural garnets and well graded.
Remember that garnet has a hardness of 6 1/2 -- 7 1/2. If you are
quartz or harder you probably need carborundum (or lots of time).
Garnet, like carborundum, will break down over time because it is
brittle. So go ahead and use them in regular grades, if you have
If you have only coarse or mixed grit, running it out will probably
work, much like with corborundum (aka, corundum, carbo, "grit").
little bit of carbo mixed in sometimes helps speed the process.
suprised if it takes longer.

One of my good friends passed away and his widow asked me to evaluate
aquamarine rough. I do not facet, but I do lots of cabochons so
little knowledge of the rough prices. Can any one give me a price
some pretty good looking stuff?
Subject: Star sapphires
Date: Tue, 4 Feb 2003 07:08:53 -0700
This is my first time to post a question, so it is a new experience.
have approximately a pound of star sapphire rough that looks like
many rocks but they all have the ability to star. They also change
appearance drasticly when polished. I bought this rough to practice
but so far I seem to be missing the mark. Is there an easy
locating the correct position to grind the stone?

Great tips ! I was not aware of the delicate balances of water.
I like your idea of possibly transferring to a different tumbler
polishing. I will try that trick with a different vibrational tumbler
I have found that slabs need to be separated by up to 80%, non-slab
materials...Lapping together / the sticking together of slabs is
problem.. No grinding, sanding or polishing will otherwise occur,
slabs are free to receive the carbides and aluminas..
Perhaps I will also increase the power, it's just that the increased
doing so, is a big concern for me in my current living situation..
