Diamonds: Jacob & Co.
Diamonds from India’s historic Golconda mines are among the world’s most coveted stones, so it’s clear what makes Jacob & Co.’s 40.05-carat, D-flawless Golconda pendant a true prize. Set together with a 6.76-carat D-flawless stone—also a Golconda—and a dazzling Colombian emerald, the Eye of Golconda pendant’s awe-inspiring centerpiece diamond reflects the extraordinary clarity that the nitrogen-free stones from the age-old mines are known to possess.

Among the purest diamonds on Earth, Golconda stones like this pendant’s centerpiece are so clear that they are often described as pools of water.
By 1725, the Golconda mines—named for the 14th-century Indian sultanate in which they were located—were fully depleted, but stones with provenances traceable to the quarries are still in high demand.
