01Red Spinel price by carat size
02In our stock, larger red spinel costs more per carat — a big clean stone is rarer than two small ones.

What moves the price
03Two stones of the same weight can differ several times in price. Colour comes first, its saturation and evenness, then clarity, the quality of the cut, origin and treatment. Every listing states each of these, so you can compare like with like.
