Preferably something abstract or pictoral. I want the logo to represent the process of refinement. If you could make a logo that represents ore turning into gold, or gold being extracted from ore, or any other ideas you have that can show refinement taking place I would appreciate it. Also, I would prefer the logo isn't focused around the letter R.

Refinement:
1) the improvement or clarification of something by the making of small changes
2) cultured elegance in behavior or manner
3) the process of removing impurities or unwanted elements from a substance

Colors: gold, silver, white, black

Thank you everyone for your submissions! I couldn't decide on three finalists because I liked them all so much so I had to relist the contest :)
