I own Black Cherry & it is one of my favorites so when I bought this I thought it would be different. Well, on the eye it looks the same so it looks like I just bought myself another Black Cherry. Applied thicker than I'd draw a lash line, on my hand, you can see it has a teensy bit more violet to it. That being said, I rated it a 4 since I like the color of Black Cherry more, but they are so close I wouldn't buy both unless you were running out of the other.
I got this in a Mally kit of several products, this color was supposed to be exclusive to QVC. As far as I can see, this is the exact same color as the existing Starlight liner in Black Cherry. I don't see any difference whatsoever. But just like all other Starlight liners, this is very creamy, glides on without tugging and generally is heavily pigmented. Black Violet is a soft black with a hint of plum in some lights. Like all the other Starlight liners, this does have great lasting power, and lasts all day for me, which is what I really need in a liner. I doubt I would buy it again, it's just not that much of a 'wow' color. Nice enough but nothing special.
