About this 1.58ct lab-grown oval diamond

This 1.58ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included) and certified by IGI LG455030260 or 455030260. Listed at a single retailer as of October 29, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
