About this 4.23ct lab-grown oval diamond

This 4.23ct lab-grown oval sits in the three to five carat band, graded D colour (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 1525315059. Currently listed at a single retailer. If it later appears at another store, Carat Hunter will surface the price comparison automatically. Lab-grown prices in the 2ct and up range have fallen 40 to 60% over the last 18 months. Use the cross-retailer spread above to find the lowest current listing.
