This 1.55ct lab-grown oval sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG842615314 or 842615314. Listed at 2 retailers as of October 29, 2026, with prices from £423 to £1,158, a £735 spread on the same certified stone. MOH London lists it at £1,158. 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.
