Kara Ross, the American designer jewelry that is appreciate to people like Michelle Obama (https://gioiellis.com/kara-ross-piace-michelle-obama), Oprah Winfrey and Demi Moore, loves contrasts. She likes the combination of old and new, worked and raw, chiseled and smooth. This is evident in the Petra collection, which takes its name from the great archaeological site in southern Jordan. A series of rings using the strong contrast stressed by a division into two of the upper part of the jewel. A thin strip of gold, wavy, with small diamonds, marks the border between the rough stone, as found in nature, and the area worked by human hands. Result: the crystals of the gems that are found in their natural state are often even more fascinating of the stones cut in geometric dimensions. Amethyst, opal blue, hemimorphite blue, green chrysocolla, uvarovite: stones that look just emerged from subsoil assume an unexpected dimension. On the other hand, the designer is also a gemologist: one who understands the value, origin and characteristics of the stones that triumph on the jewelry he designs. Lavinia Andorno
