About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555002677. Listed at 7 retailers as of October 31, 2026, with a 53% 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.
