The Purple Orchid

Showcasing as a star at the 2014 Hong Kong Jewelry and Gem Fair, the Purple Orchid began as a four-carat rough diamond from an undisclosed mine in South Africa.

Purple diamonds of this calibre are incredibly rare, making the Purple Orchid a true gem among gems.


The Daria-i-Noor, meaning “sea of light” in Persian, weighs 182 carats and boasts a pale pink hue. Extracted from India’s Golconda Mine, this diamond’s history is as rich as its colour. Passed from one dynasty to another, it’s now part of the Iranian crown jewels. Researchers speculate that it was once part of a bigger pink diamond that adorned the Mughal emperor Shah Jahan’s throne, adding to its mystique and grandeur.
