About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 751508138. Listed at 16 retailers as of November 1, 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.
