About this 0.91ct lab-grown oval diamond

This 0.91ct lab-grown oval sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included) and certified by IGI LG588357820 or 588357820. 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.
