About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded G 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 2566722245. Listed at 14 retailers as of October 31, 2026, with prices from €679 to €1,508, a €829 spread on the same certified stone. Flawless Fine Jewelry lists it at €1,508. 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.
