About this 0.51ct lab-grown radiant diamond

This 0.51ct lab-grown radiant sits in the half to three-quarter carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG588368554 or 588368554. Listed at 12 retailers as of October 31, 2026, with a 780% 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.
