About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 810629284. Listed at 3 retailers as of October 31, 2026, with a relatively tight 19% 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.
