About this 25.09ct natural round diamond
This 25.09ct natural round sits in the over five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade and certified by IGI. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
