About this 1.7ct natural marquise diamond

This 1.7ct natural marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7551635158. Listed at 7 retailers as of November 2, 2026, with a 26% 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.
