About this 0.65ct natural marquise diamond

This 0.65ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included) and certified by GIA 1152523028. Listed at 2 retailers as of October 31, 2026, with a relatively tight 4% 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.
