Precious gems are one of the Earth’s best-hidden secrets. A fortuitous clashing of tectonic forces and minerals over thousands of years resulted in the creation of bewitching jewels, so rare and sought-after through the ages. Even today, massive discoveries of such gems like emeralds, diamonds and rubies continue to astound the world.

Even fewer gems are considered to be the pinnacle of the jewellery world. These natural wonders, such as the Kashmir sapphire or Colombian emerald, are found only in specific countries. These jewels are blessed with the presence of rich minerals, birthing a myriad of intense colours without modern tamperings such as heat treatments and artificial radiation.
