Listed at 14 retailers as of October 25, 2026, with prices from $705 to $2,136, a $1,431 spread on the same certified stone. Reve Diamonds lists it at $2,136. 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.
