About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7566364420. Listed at 21 retailers as of October 30, 2026, with prices from HK$55,645 to HK$124,902, a HK$69,257 spread on the same certified stone. NZ Jewellers lists it at HK$124,902. 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.
