What do you do when you have concrete mix close to you?
In my case, jewelry. LOL.
Long story short, I want a concrete countertop -nah, not done yet, just a project- and searching for them found a lady that makes candle containers with concrete and gold leaf! Hey, yeah!!! 
Concrete in hand, "artificial gold leaf" on the other -I use the real gold sheets but not for experiments, ehem- and a mini ice cubes mold and here ya go! Industrial postapo with a touch of bling glamour. 
This elements can be used for earrings or for necklaces or as a pendant, they have quartz spikes -one is titanium gold and the other a natural clear- set in copper with its industrial glamour on top and their top loops. 
FUN! -But filthy, LOL, anyway with the home with repairs and working people, whooooo cares!!!-
They measure approx. 57 x 15mm and 55. 2 x 15mm
