This 5.03ct lab-grown marquise sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG689546575 or 689546575. Listed at 10 retailers as of October 24, 2026, with prices from $1,161 to $4,272, a $3,111 spread on the same certified stone. Taylor and Hart lists it at $4,272. 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.
