Listed at 2 retailers as of November 4, 2026, with prices from $1,297 to $1,538, a $241 spread on the same certified stone. Diamond Quarter lists it at $1,538. 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.
