Our Legacy

The Star of the South

The Star of the South is presumably the first diamond from Brazil to receive international fame. Royal Coster Diamonds was responsible for turning the rough diamond into the elegant oval form with its unique colour scheme. This extraordinary piece of craftsmanship continues to impress diamond cutters around the world up till this day.

Our Legacy

The Star of the South,
a treasure for freedom

The Star of the South was accidentally discovered in 1853 by a slave working the mines near the city of Estrala do Sul in the north of Brazil. By offering the rough stone to her master, she was rewarded with her freedom and a pension for life, as the value and magnitude of her find was immediately clear to her superior.

The Star of the South travels north

The owner of the rough diamond, master Casimiro de Tal, thought he made the deal of his life when he sold the diamond for a modest 3,000 pounds. Soon enough though it became that he strongly undervalued his possession, when the purchaser received an advance of 30,000 pounds alone by bringing it to a bank in Rio de Janeiro. After passing through several hands it eventually arrived in Amsterdam when it was bought to Royal Coster Diamonds.

Our Legacy

Royal Coster Diamonds and The Star of the South

Royal Coster Diamonds had already made quite a name for themselves after re-polishing the famous Koh-i-Noor. Mr. Coster trusted the same diamond polisher, Louis Voorzanger, to cut this diamond into another masterpiece. The rough diamond would lose almost half of its original weight, slimming down from 254.50 to its current 128.48 carats. By changing the shape of the diamond, Voorzanger created an unique phenomenon. The diamond reflects a perfect white light, but the refracted light gives it a slightly pink character. Yet another fine example of Royal Coster’s craftsmanship!

Our Legacy

What happened to The Star of the South?

More beautiful than ever before the cut diamond was sold by Royal Coster Diamonds to a French syndicate of diamond merchants. It was only then that the diamond received its current name, The Stone of the South, referring to its original finding place, Estrala do Sul. After being exhibited on several locations the diamond changed owners and moved to India for a long period. Until the beginning of this century, when the family Cartier bought the Star of the South. They can call themselves proud owners of one of the most beautiful diamonds you’ll ever see!
