About this 0.63ct natural asscher diamond

This 0.63ct natural asscher sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7531969137. Listed at 4 retailers as of October 31, 2026, with prices from £321 to £419, a £99 spread on the same certified stone. Blue Nile lists it at £419. 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.
