About this 4ct lab-grown round diamond

This 4ct lab-grown round sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG833605350 or 833605350. Listed at 12 retailers as of October 29, 2026, with prices from €1,114 to €4,178, a €3,063 spread on the same certified stone. MOH London lists it at €4,178. 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.
