Ruby

Smaragdus · the green fire of the earth
Born of beryllium drawn upward through the roots of mountains, the emerald has bewildered jewellers and emperors for five millennia. From the desert mines of the Pharaohs to the Mughal ateliers of Jaipur, this stone has been a vessel for foresight, fidelity and rebirth. Within these folios, our masters at Birla Enterprise present the emerald as it has been kept — studied, set, and revered.
