Corundum is a Sanskrit word that goes back millennia, as do the two classic colored precious gemstones, namely, Rubies and Sapphires. Rubies are the rarest and most prized Red variety of Corundum. Sapphires on the other hand are comprised of all other colors, ranging from Blue, Yellow, Pink, Green, and Purple. Paparadsha Sapphire refers to a rare color which resembles an Pinkish-Orange color found in Lotus flowers. Marina D design is inspired by classic lines, and often guided by the gemstone we are working with. Often, the center stone shape, color, and clarity give the designer some cues, and we consult with our clients to capture their preferences. All Marina D creations in this collection are finished in 18K Gold or Platinum.
