About this 0.45ct lab-grown oval diamond

This 0.45ct lab-grown oval sits in the sub-half-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG620454627 or 620454627. 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.
