Listed at 8 retailers as of November 2, 2026, with prices from $1,677 to $5,224, a $3,547 spread on the same certified stone. With Clarity lists it at $5,224. 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.
