This 5.15ct lab-grown marquise sits in the over five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG761505321 or 761505321. Listed at 4 retailers, with prices from $3,050 to $7,100 at Zales, a $4,050 spread on the same certified stone. 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.
