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 LG846647328 or 846647328. Listed at 13 retailers as of November 1, 2026, with a 156% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
