About this 3.15ct lab-grown cushion diamond

This 3.15ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1445189976. Listed at 11 retailers as of October 31, 2026, with a 283% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
