Does Carat Hunter earn commission from either store?

No. We earn zero affiliate revenue from any retailer in our index.

Why do you not show price comparisons on this page?

Pricing varies per stone, not per store. Click through to any matched diamond above and you'll see both retailers' prices on the exact same physical stone, which is the real comparison.

How fresh is this data?
