About this 1.05ct natural marquise diamond

This 1.05ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 809656257. Listed at 4 retailers as of November 2, 2026, with a relatively tight 25% 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.
