About this 1.51ct natural princess diamond

This 1.51ct natural princess 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 2566680556. Listed at 4 retailers as of November 4, 2026, with prices from HK$20,319 to HK$24,725, a HK$4,406 spread on the same certified stone. Michael Trio lists it at HK$24,725. 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.
