About this 1ct natural asscher diamond

This 1ct natural asscher sits in the classic one-carat band, graded H 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 1565487301. Listed at 8 retailers as of October 31, 2026, with prices from $2,257 to $4,379, a $2,122 spread on the same certified stone. MOH London lists it at $4,379. 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.
