This 1.6ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754594272 or 754594272. Listed at 17 retailers as of October 31, 2026, with prices from $479 to $5,731, a $5,252 spread on the same certified stone. Brilliant Earth lists it at $5,731. 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.
