This 0.42ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG756513927 or 756513927. Listed at 11 retailers as of October 30, 2026, with prices from $409 to $2,399, a $1,991 spread on the same certified stone. Kay Jewelers lists it at $2,399. 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.
