I struggle to understand the price difference between diamonds at online retailers. I understand the 4Cs, but I see many times where diamonds that look identical to me have a huge cost delta. I won’t pay extra for something that doesn’t matter, but I won’t skimp if it makes a difference.
For example, I don’t understand why the 2nd diamond on James Allen below costs almost $ 2K more when they look the same on almost everything down to fluorescence:
1) [https://www.jamesallen.com/loose-diamonds/round-cut/1.25-carat-e-color-vs2-clarity-ideal-cut-sku-7339082](https://www.jamesallen.com/loose-diamonds/round-cut/1.25-carat-e-color-vs2-clarity-ideal-cut-sku-7339082) – $ 3200
2) [https://www.jamesallen.com/loose-diamonds/round-cut/1.25-carat-d-color-vs1-clarity-excellent-cut-sku-6988240](https://www.jamesallen.com/loose-diamonds/round-cut/1.25-carat-d-color-vs1-clarity-excellent-cut-sku-6988240) – $ 5140
What am I missing here? Any help would be great.
