About this 0.3ct natural oval diamond

This 0.3ct natural oval sits in the sub-half-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 815640197. Listed at 8 retailers as of October 29, 2026, with prices from $344 to $800, a $457 spread on the same certified stone. MOH London lists it at $800.
