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 very-good cut grade and certified by IGI LG799680887 or 799680887. Listed at 8 retailers as of October 30, 2026, with prices from $2,480 to $12,205, a $9,725 spread on the same certified stone. Diamonds Direct lists it at $12,205. 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.
