This 1.89ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG811640897 or 811640897. Listed at 9 retailers as of October 30, 2026, with prices from $1,030 to $6,303, a $5,272 spread on the same certified stone. Do Amore Diamonds lists it at $6,303. 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.
