About this 1.03ct lab-grown marquise diamond

This 1.03ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG772699409 or 772699409. Listed at 21 retailers as of October 29, 2026, with a 484% 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.
