About this 0.42ct natural oval diamond

This 0.42ct natural oval sits in the sub-half-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1555903987. Listed at 2 retailers as of October 31, 2026, with prices from HK$2,550 to HK$3,469, a HK$919 spread on the same certified stone. 77 Diamonds lists it at HK$3,469. 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.
