You guys do great renders! So nice to be here! 
It was hard weekend and I don’t have much time, but I hope you like my work:
“Heart of the stone”
Stone of course don’t have heart like human heart but in terms of some esoteric vibe, they may have some energy and own mood.
Update.
It’s like this sentence could be in poem.
“The heart of stone is calling me.”
That’s what I was trying to show as “personification”.
I use “Procedural Noise Texture Pack” from Simon Thommes
and HDRI from HDRIHaven
Grass is from Gleb Alexandrov’s tutorial download from blendswap.com
I had fun working with the main heart shader and these light points!
