Famous Emerald Diamond Rings - Royal Coster Diamonds

Famous Emerald Diamond Rings

As the name suggests, this diamond shape was initially for the emerald gemstone. One of the key features for this cut is that only the purest of diamonds are suitable for this shape. That's why emeralds are often used as a special wedding- or engagement ring. The Emerald of Melania Trump is one of the famous emerald diamond rings, but certainly not the most expensive or largest. With this a few great examples:

The Emerald diamond engagement ring of Jennifer Lopez
