About this 0.42ct natural asscher diamond

This 0.42ct natural asscher sits in the sub-half-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5181602494. Listed at 2 retailers as of October 31, 2026, with prices from £558 to £665, a £107 spread on the same certified stone. Yorxs lists it at £665. 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.
