About this 3.7ct lab-grown oval diamond

This 3.7ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG591334461 or 591334461. Listed at 5 retailers as of October 31, 2026, with prices from £913 to £3,876, a £2,963 spread on the same certified stone. Michael Trio lists it at £3,876. 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.
