3 things to know when choosing an emerald cut diamond platinum engagement ring!

  1. Hall of Mirrors: To find the best “hall of mirrors” effect in a platinum emerald cut engagement ring, focus on looking for a stone with alternating dark and light facets. The emerald cut is a “stepped” gem, meaning that it has long, rectangular facets. So, when looking for the best hall of mirrors, follow the stepped vertical facets. These should be straight, a mirror image of each other, and show excellent contrast. Learn more about hall of mirrors effect here!
  2. Proportion: When selecting an emerald cut diamond, one thing to consider is length-to-width (L/W) ratio. This measurement shows how skinny or plump your emerald is. Some people prefer a long, elegant emerald cut, almost reminiscent of a baguette. Others prefer a more plump stone, which edges more towards an asscher cut. The vast majority, however, typically prefer a stone around 1.30-1.40 ratio.
  3. Platinum Patina: The soft patina of platinum beautifully complements the graceful hall of mirrors in an emerald cut diamond. As your emerald cut platinum engagement ring acquires its patina over time, your stone is sure to be enriched by the vintage sheen. This gentle, satin finish complements the emerald’s hall of mirrors, adding depth and character to the ring. Together, platinum’s patina and emerald’s dramatic hall of mirrors offers a sophisticated engagement ring.
