Listed at 26 retailers as of October 30, 2026, with prices from $923 to $3,135, a $2,213 spread on the same certified stone. NZ Jewellers lists it at $3,135. 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.
