Help ID this Coral

[msjboy]

Hello,

I just got a frag of this but the owner doesn't quite know what it is. It is grey/blue in colour and accurately shown in picture under white/blue light. The picture of the coral is about ones thumb size. I is not a stoney coral but probably a finger leather or ridge coral of some type to my best of knowledge. Thanks a bunch.

My guess is Heliopora (Blue Ridge Coral).
