About this 0.3ct lab-grown marquise diamond

This 0.3ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG683547463 or 683547463. Listed at 19 retailers as of October 29, 2026, with a 611% 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.
