This limited edition of 20 pieces is made of Labradorite with ebony accents. Labradorite is one of the most beautiful stones in the world, originally discovered in Labrador, Canada. These stones, however, come from Madagascar. Rich colors luminesce as light reflects through the stone. Color can range from rich green, to purple, royal blue, and in rare cases gold. After cuttin the stone for the barrel, I also cut two cabachons for the top of the cap as well as in the tail piece of the barrel. For this pen, I have used solid sterling silver components and a solid 18k gold nib. The cap is made of macassar ebony and has the edition number engraved The price is $1700 please contact us to discuss color options. Rollerballs are available as well. There is a 3-4 week delivery on this item.
