About this 1.24ct lab-grown marquise diamond

This 1.24ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG770608458 or 770608458. Listed at 27 retailers as of November 4, 2026, with a 788% 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.
