I’ve had good experience with every Private Reserve ink I’ve used up to this point so I had no concerns about the quality of the ink. My goal was to find a purple that I loved and Ebony Purple was recommended to me buy the fine folks at Goldspot Pens as a color I might just love. I got the 50ml bottle of Diamine Ebony Purple for $10. While its not the prettiest bottle in the world, its easy to use with a simple, cylindrical shape and a wide mouth that makes it easy to refill pens.
Ebony Purple definitely lies on the the darkest end of the spectrum and more violet than purple. Because the color is so dark there’s not a lot of shading. In my waterproof tests you can see the blue and the red undertones in the ink. The ink is definitely not waterproof but makes it easy to clean out of the pen.
I’m not a huge fan of plain black inks so Ebony Purple is a good alternative for a dark ink that’s respectably blackish but with some personality. I like it for this quality but my search for the “perfect purple” continues.
