GIA 4Cs of Diamond Quality
Wonder of Nature
There is no other gemstone quite like a diamond. It is found in the most remote places on earth, and the fact that it forms at all is something of a miracle. It takes about one ton of rock to recover less than half a carat of rough, making diamond one of the rarest and most desired gemstones in the world. A diamond is a testament of endurance and strength – and not surprisingly, the ultimate symbol of love.
