About this 3.7ct lab-grown radiant diamond

This 3.7ct lab-grown radiant sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG607310956 or 607310956. Listed at 23 retailers as of November 2, 2026, with prices from $441 to $4,270, a $3,829 spread on the same certified stone. Brilliant Earth lists it at $4,270. 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.
