Listed at 19 retailers as of October 29, 2026, with prices from $178 to $1,580, a $1,402 spread on the same certified stone. Kay Jewelers lists it at $1,580. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
