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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555422815. Listed at 24 retailers as of October 30, 2026, with prices from HK$40,039 to HK$94,263, a HK$54,224 spread on the same certified stone. NZ Jewellers lists it at HK$94,263. 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.
