About this 0.54ct lab-grown radiant diamond

This 0.54ct lab-grown radiant 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 LG830658055 or 830658055. Listed at 20 retailers as of October 30, 2026, with prices from $148 to $993, a $845 spread on the same certified stone. Michael Trio lists it at $993. 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.
