Twenty-five carats puts this malachite in the bigger half of what we list. Malachite stones are commonly large because the material is soft and not rare, so a piece of this weight is normal rather than exceptional. Its price shows it: Rs. 4,050, about Rs. 159 per carat.

A stone this size changes how you wear it. On a ring it will cover a good part of the finger, so it suits a bold design and a hand that does not do rough work. As a pendant it hangs with some weight, and the deep green banding is easy to see from a distance.
