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 2556750792. Listed at 23 retailers as of November 5, 2026, with prices from HK$42,534 to HK$95,138, a HK$52,605 spread on the same certified stone. NZ Jewellers lists it at HK$95,138. 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.
