About this 1.03ct lab-grown marquise diamond

This 1.03ct lab-grown marquise sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG783636421 or 783636421. Listed at 24 retailers as of October 30, 2026, with prices from $179 to $1,126, a $947 spread on the same certified stone. Reve Diamonds lists it at $1,126. 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.
