About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2386505851. Listed at 18 retailers as of November 4, 2026, with prices from HK$21,600 to HK$49,007, a HK$27,407 spread on the same certified stone. NZ Jewellers lists it at HK$49,007. 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.
