About this 2.78ct lab-grown radiant diamond

This 2.78ct lab-grown radiant sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7506164040. Listed at 19 retailers as of October 27, 2026, with prices from HK$15,348 to HK$115,656, a HK$100,308 spread on the same certified stone. Zales lists it at HK$115,656. 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.
