About this 1.23ct natural oval diamond

This 1.23ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2487659567. Listed at 5 retailers as of November 5, 2026, with prices from HK$23,645 to HK$37,995, a HK$14,350 spread on the same certified stone. 77 Diamonds lists it at HK$37,995. 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.
