About this 1.28ct natural marquise diamond

This 1.28ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 778617650. Listed at 21 retailers as of October 30, 2026, with a relatively tight 20% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
