About this 1.03ct lab-grown marquise diamond

This 1.03ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816615177 or 816615177. Listed at 9 retailers as of November 5, 2026, with a 755% 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.
