About this 1.25ct lab-grown heart diamond

This 1.25ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG522231503 or 522231503. Listed at 16 retailers as of October 28, 2026, with prices from HK$2,558 to HK$11,636, a HK$9,078 spread on the same certified stone. Michael Trio lists it at HK$11,636. 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.
