This 2.71ct lab-grown cushion sits in the two to three carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG526271050 or 526271050. Listed at 11 retailers as of November 1, 2026, with prices from £1,423 to £10,467, a £9,044 spread on the same certified stone. Reve Diamonds lists it at £10,467. 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.
