About this 0.39ct lab-grown marquise diamond
This 0.39ct lab-grown marquise sits in the sub-half-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GCAL 312570072. Listed at 7 retailers as of October 31, 2026, with a 342% 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.
