Ruby in Zoisite from Tanzania is a combination of two distinct minerals, with deep red ruby crystals naturally embedded in green zoisite. This contrast of colors occurs due to the different mineral compositions, with ruby being an aluminum oxide and zoisite a calcium aluminum silicate. The presence of black hornblende inclusions further enhances its visual appeal and helps differentiate it from other ruby-bearing rocks.
