About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included) and certified by GIA 5553995690. Listed at 14 retailers as of October 30, 2026, with a 133% 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.
