A ravishing 0.15-carat True Antique cushion diamond is nestled in a valley between four Paraiba peaks. Natural Paraiba cabs weigh 0.85 carats total. Paraíba is a cupriferous (iron-bearing) variety of tourmaline found only in Brazil and West Africa. It is characterized by it’s unique electric-blue-green color that no other gem possesses. Bezel-set natural pink pear-shaped diamonds surround the center. The three lines of the pave shank are set with natural pink and white diamonds.
