About this 1ct lab-grown marquise diamond

This 1ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG850685503 or 850685503. Listed at 12 retailers as of November 1, 2026, with prices from $174 to $1,050, a $876 spread on the same certified stone. Reve Diamonds lists it at $1,050. 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.
