1.24ct Fancy Intense Blue Lab Diamond Solitaire

The rich intense hues of this 1.24ct VVS2 IGI-certified blue diamond cannot be overstated. The sophisticated stepped linear facets of square emerald cut add a mesmerising depth to this exceptional coloured diamond.

Natural blue diamonds are so rare that when then come up for sale, they often command prices in the 10s of millions. Why they attract such remarkable prices is because they remain one of the Earth’s deepest secrets.

According to geologists, these wonders of the natural world were formed in the hot layer between the earth’s crust and its core, at depths reaching 400 miles, over 500 million years ago. Up until now, chances are, if you own a blue diamond, you are in possession of something that is one billion years old. Scientists have discovered that they develop their brilliant blue colour from the mineral boron, which is found in the ocean.
