Yellow Gold Rough Diamond Stud Earrings This collection is all about the rough Brown Diamond being the focus of the jewel, as the simple lines are created around the Diamond to make it stand out, 18 carat Yellow Gold gives it a different tint to the stone. The 9kt being a little red in colour makes gives a slight dipper tint to the Diamond, the 18 karat having a yellow tone gives a brighter look. Since this rough diamond is used exactly how it was found in nature, each stone will vary in size and colour. Each Diamond is unique so your jewel will be a one off. The Stud earrings hold the Rough Diamond with as much metal needed to hold it safe but not overpower to cover the natural shape. Can be worn daily for a glamorous look.
