This 0.37ct lab-grown round sits in the sub-half-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG12677801 or 12677801. Listed at 2 retailers as of October 27, 2026, with prices from €438 to €580, a €142 spread on the same certified stone. The Diamond Guys lists it at €580. 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.
