Stone block with red veins and a black spot?

I stumbled on this stone block at Z-16 that illuminates some light. It has red/pink veins and a dark black spot about 1/16 the size of a single block. I cannot mine it with my iron pickaxe. I tried googling it but cannot find anything related. I have the Soartex texture pack and the latest FTB unleashed installed. Anyone knows what this is and what it yields when mined?

Solution 1:

The type of hive is called a Deep Hive and it contains Attuned Bees. It is added by the Magic Bees mod (formerly referred to as Thaumic Bees). Here's the default texture:

As with all beehives, you collect the bees from it by breaking it with a Scoop.

Solution 2:

It looks like one of the Beehives. Use a scoop on it. Make a scoop by placing sticks in a crafting table in the shape of a Y or a 2 prong fork, and place a wool block in the middle of the top part.

Solution 3:

This is a beehive. I have personally found, and harvested these blocks many times. I have never been able to (ever) find any information as to why these particular hives look different, or if extra bees or thaumatic bees has any part in why they look different. Next time I find one, I'll screenshot myself breaking it to get bees.

For the sake of acuracy, this hive was found in the Twilight Forest, in a cave, and it gave me an Attuned Princess.
