About this 3ct lab-grown cushion diamond

This 3ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG432012446 or 432012446. Listed at 5 retailers as of October 29, 2026, with prices from $2,654 to $15,346, a $12,692 spread on the same certified stone. MOH London lists it at $15,346. 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.
