Listed at 18 retailers as of November 4, 2026, with prices from $255 to $2,050, a $1,795 spread on the same certified stone. Helzberg Diamonds lists it at $2,050. 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.
