About this 3.7ct lab-grown radiant diamond

This 3.7ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG719515527 or 719515527. Listed at 22 retailers as of October 27, 2026, with a 358% 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.
