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 HK$17,252 to HK$21,852, a HK$4,600 spread on the same certified stone. Michael Trio lists it at HK$21,852. 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.
