About this 1.4ct natural oval diamond
This 1.4ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6237918691. Listed at 12 retailers as of November 4, 2026, with a 71% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
