This is the first time a Hg-S-bearing inclusion named arzakite has been described in ruby. The presence of arzakite is a product of the genesis of ruby in marbles, in which the metamorphism of the sedimentary protolith at very high temperature in a closed system where fluids could not escape. The fusion of the mixture of the protolith nucleated an alkaline-salty magma where all the chemical elements combined, forming ruby and minerals such as arzakite. This finding underscores the importance of detailed inclusion studies offering critical insights into the formation of gems such as Mogok ruby in Myanmar.
