About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5563124132. Listed at 11 retailers as of November 6, 2026. 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.
