L’ Incomparable

This necklace is made by Lebanese jewelers Mouawad, dubbed L'Incomparable, boasts the world's largest internally perfect diamond. The 407ct yellow step-cut diamond is suspended from a rose gold necklace set with 91 white diamonds totaling more than 200 cts, placed in an asymmetrical arrangement that resembles vine leaves.

A young girl in the African Congo discovered the spectacular centerpiece diamond by mistake in an abandoned mound of mining rubble in the 1980s. Before being combined into this exquisite Mouawad necklace, which was first revealed at the Doha Jewelry and Watch Exhibition in 2013, it was displayed in museums like the Smithsonian Institution in Washington, DC.

L’ Incomparable, on the other hand, makes little fuss thanks to its simple design. This serves a purpose, since a simple style would be ideal for emphasizing the presence of the magnificent diamond. Apart from the stone, the Mouawad L'Incomparable Diamond Necklace is made up of gleaming diamonds in a variety of cuts, including brilliant, pear, and emerald, set in a rose gold base.
