About this 0.42ct lab-grown marquise diamond

This 0.42ct lab-grown marquise sits in the sub-half-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG740505417 or 740505417. Listed at 17 retailers as of October 30, 2026, with a 546% 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.
