Listed at 19 retailers as of October 30, 2026, with prices from $813 to $4,487, a $3,674 spread on the same certified stone. Brilliant Earth lists it at $4,487. 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.
