This 1.71ct lab-grown oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG566393346 or 566393346. Listed at 19 retailers as of October 27, 2026, with prices from £393 to £1,632, a £1,238 spread on the same certified stone. Brilliance lists it at £1,632. 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.
