This 0.51ct lab-grown asscher sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG662464535 or 662464535. Listed at 2 retailers as of October 31, 2026, with prices from $283 to $1,395, a $1,112 spread on the same certified stone. Diamond Quarter lists it at $1,395. 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.
