Esterbrook Diamondcast Sparkle Montana Sapphire Fountain Pen

This pen is lovingly used and comes with a box, no papers. It is equipped with a Steel Medium nib and fills via cartridge convertor (included).

The Estie has been an integral part of the revival of the new Esterbrook brand. It’s sleek and stately in the hand and a great writing instrument for everyday use and special occasions.  

This gem of a pen has had a glitzy makeover and is one of their most ambitious Estie models to date.  

As Esterbrook is committed to collaborations with US makers, they partnered with Tim McKenzie of McKenzie Penworks in Charlotte, NC. 

Tim McKenzie of McKenzie Penworks in Charlotte, NC is a custom Alumilite blank maker who wanted to separate himself in the marketplace. How to make one’s product unique is a challenge to artisans throughout the industry, so Tim got innovative and added diamonds to his mix of Alumilite and pigments.

Taking knowledge and advice from his mother, a GIA certified gemologist, and conducting his own research and experimentation, Tim figured out the precise size diamond particles needed to be to allow his pen material to be machined effectively without losing the intense sparkle of the precious gems.

Using reclaimed diamond particles from diamond cutters, McKenzie takes what would be wasted and instead, upcycles it and makes it into a material that shines and glimmers with light in each move of the resulting pen.

Now patent pending, McKenzie’s Diamondcast material has made a big impression and enchanted custom penmakers all over the globe.

Staying with Esterbrook’s tradition of utilizing as many American made materials as possible, we approached Tim to partner with us to make a new version of our oversized Estie, because let’s face it, if you’re going to have a pen made with diamond dust, it has to be supersized and we wanted to use his material in the most epic way we could.

The result is the Estie Sparkle, Montana Sapphire (which has the addition of silver to make it even more of a showstopper).
