About this 0.4ct lab-grown heart diamond

This 0.4ct lab-grown heart sits in the sub-half-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG677506127 or 677506127. Listed at 14 retailers as of October 29, 2026, with prices from HK$620 to HK$5,640, a HK$5,020 spread on the same certified stone. MOH London lists it at HK$5,640. 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.
