Iron-Bearing Rhodochrosite on Quartz

Rhodochrosite crystals on double layered grey quartz. The usual pink/red colour rhodochrosite has been replaced with orange to yellow tones due to the iron inclusions. 

Locality: Bulgaria 

Do note: this piece had only the locality & no mineral name so I researched this piece and based off of a trusted seller and locality I’ve narrowed it down to being rhodochrosite with iron, however I’m not 100% certain.
