Colored or fancy Diamonds as they are known are definitely the rarest and most expensive gems on the planet. Intense shades of pink can even sell for over $1,000,000 per carat, that's of course if you can find them. We have set a lab-created cushion cut pink Diamondeau - flawless simulated diamond weighing a staggering 3 carats into our gorgeous Carina ring. The exquisite tension style mount holds this gem securely, whilst in profile it shows it off in its full glory. The solid sterling silver setting is lavishly plated in buttery 18k gold to bring out the warm tone at the center of the stone.
