About the Item
Contemporary 3.10ct Rhombus Modified Brilliant Cut Diamond Solitaire Engagement Ring in 19.2 Karat White Gold, Bespoke, circa 2010s. This handmade one-of-a-kind jewel features a beautiful diamond with a shape which is very rare to come across with – so rare that it is often emulated by putting several smaller stones together, such as two trilliant-cut diamonds, to create the same final rhombus, lozenge or diamond shape. The stone is half bezel-set in a white gold ring which seems to have the magic and elegance of a twisted tension design, but which is supported by concealed metal galleries to ensure the safety of the diamond for generations to come.
As you can see from the pictures and video, this diamond-shaped diamond has the fire and sparkle of a brilliant-cut, but with a geometrical twist. It is a jewel with personality, which captivates everyone who glance at it. It is the kind of stone that everyone would say "yes" to.
Diamond: 3.10 carats; J/K color; SI1 clarity. Lisbon hallmark for 19.2kt gold (800/1000); maker's mark for Lisbon jeweler Amaro Coelho. Finger size: 54 (EU), but can be sized up or down. Gross weight: 9.62g.
