About this 1.71ct natural marquise diamond

This 1.71ct natural marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 813641942. Listed at 6 retailers as of October 31, 2026, with a 42% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
