This 3.66ct lab-grown radiant sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG847664085 or 847664085. Listed at 11 retailers as of October 27, 2026, with prices from $1,030 to $4,167, a $3,137 spread on the same certified stone. Taylor and Hart lists it at $4,167. 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.
