About this 3.78ct lab-grown round diamond

This 3.78ct lab-grown round sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GCAL 323430007. Listed at 15 retailers as of October 29, 2026, with prices from HK$3,860 to HK$22,160, a HK$18,300 spread on the same certified stone. MOH London lists it at HK$22,160. 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.
