About this 1.3ct lab-grown marquise diamond

This 1.3ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG594328028 or 594328028. Listed at 17 retailers as of November 1, 2026, with prices from $445 to $1,220, a $775 spread on the same certified stone. Reve Diamonds lists it at $1,220. 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.
