About this 0.66ct lab-grown round diamond

This 0.66ct lab-grown round sits in the half to three-quarter carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG628473355 or 628473355. Listed at 3 retailers as of November 1, 2026, with prices from €266 to €1,156, a €890 spread on the same certified stone. MOH London lists it at €1,156. 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.
