About this 1.51ct natural asscher diamond

This 1.51ct natural asscher sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1507993435. Listed at 6 retailers as of November 4, 2026, with prices from €1,959 to €2,482, a €522 spread on the same certified stone. Michael Trio lists it at €2,482. 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.
