About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6522573772. Listed at 16 retailers as of November 4, 2026, with prices from $676 to $2,085, a $1,408 spread on the same certified stone. MOH London lists it at $2,085. 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.
