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 VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551339155. Listed at 9 retailers as of November 6, 2026, with prices from $1,292 to $2,383, a $1,091 spread on the same certified stone. With Clarity lists it at $2,383. 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.
