About this 1.5ct natural oval diamond

This 1.5ct 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 1428798393. Listed at 17 retailers as of November 1, 2026, with prices from HK$63,671 to HK$115,604, a HK$51,933 spread on the same certified stone. NZ Jewellers lists it at HK$115,604. 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.
