Listed at 18 retailers as of October 28, 2026, with prices from $276 to $2,243, a $1,967 spread on the same certified stone. Yadav Diamonds lists it at $2,243. 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.
