Listed at 5 retailers as of October 31, 2026, with prices from $7,890 to $36,142, a $28,253 spread on the same certified stone. Adiamor lists it at $36,142. 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.
