6.48 ct Cushion Red Rubies
Beautiful pair of cushion shaped rubies in rich deep red colour. This lovely ruby would make a lovely pair of earrings especially if surrounded by sparkly diamonds.
Rubies are increasingly being treated by filling with glass and stones. Rubies that have been treated in this way may contain a very large percentage of glass. If you become aware that you or a customer has such a ruby, avoid direct heat, acids, ultrasonic and steam cleaners, knocks and blows.
