Price is per blank. Multiple blanks shown to illustrate the
variety that is possible.

Dimensions: 3/4" square by 5 1/2
Description: A deep dark purple (plum?) dominates this blank with thin black matrix. Reminiscent of rare South African sugilite that is getting hard to find.
Opacity: Extremely opaque. Tubes
are not visible on even the thinnest walled kits.
Turnability: Medium, I recommend you try a few
Easy TruStone blanks and have a moderate level of turning experience.
- I recommend carbide tools for the Medium and Hard TruStone blanks. The Woodchuck Pen Pro
Carbide Tool that is available on this site is an excellent choice. HSS
tools are OK on the Easy and Medium, but will need to be sharpened more
- Go slow and allow
these blanks to cool if too much heat builds up while drilling and turning. Too
much heat can cause them to crack or shatter. Take shallow cuts and cut from the end of
the blanks towards the center to avoid stress on the unsupported ends of the
- I recommend that you do not drill all the way though the blank. Leave the blank
whole or cut oversized, then drill to the depth needed (without exiting the
blank), remove blank from drilling vise, and cut to the correct length. If needed a
sacrificial piece of wood can be glued to the end and will help prevent blow-out
- Consider using a thick walled pen kit like the Cigar or the Sierra Vista style
kits when you first start making TruStone blanks.
- If you are new to turning TruStone blanks I recommend trying the
first, and working up to the
hard blanks. Also, consider using a thick walled pen kit like the Cigar or
the Sierra Vista style kits when you first start making TruStone blanks. The
thicker walled kits will be easier to turn.
- Finish as you would finish acrylic blanks (a CA finish is not needed). I sand
through the micro-mesh grades, cleaning the blank with alcohol between grades,
and then buff with ZAM to bring out the ultimate shine.
- These are the pliable TruStone blanks, and while they have powdered stone in them the exact stone used is a trade secret. I highly doubt any semi-precious stone is used and the descriptions should not be taken to construe the presence of any specific mineral.
TruStone blanks make very impressive finished pens. The easy
blanks are within the ability of most turners, and while the medium and hard
blanks are more difficult to turn, you will be well rewarded for taking on the
challenge of these blanks when you end up with a beautiful finished pen.
