How to read the verdict
The verdict at the bottom of each comparison is not a ruling. It names the axis on which a stone wins: one might win on durability, another on color, a third on price per carat.
A reader whose axis is “budget daily wear ring” will land on a different stone than a reader whose axis is “harmless earrings with rare meaning”. The table does the math. The reader picks the axis.
Can I compare any two stones?
The hub covers popular comparisons. Where a specific pair is missing, the contact page accepts a request.
Why use tiers instead of fixed prices?
Because fixed gemstone prices shift weekly with cut, carat, origin, and treatment. A tier stays honest longer than a number.
Do comparisons include lab grown?
Yes, where the lab grown version is commercially meaningful, the comparison covers it as a third column.
