About this 3.51ct natural oval diamond

This 3.51ct natural oval sits in the three to five carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1568271548. Listed at 16 retailers as of October 31, 2026, with prices from $74,828 to $120,609, a $45,781 spread on the same certified stone. Helzberg Diamonds lists it at $120,609. 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.
