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 2564688595. Listed at 15 retailers as of October 31, 2026, with prices from $1,317 to $2,947, a $1,630 spread on the same certified stone. Flawless Fine Jewelry lists it at $2,947. 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.
