Pentagonal Cut Diamonds
The pentagonal cut is a five-sided shape — genuinely rare, deliberately asymmetric, and made for people who want a stone nobody else will be wearing.
They are cut in very small numbers, so if you find one you like at the right size it is unlikely to be repeated. You can compare natural and lab-grown stones side by side here — chemically and optically identical, differing only in origin and price. Our lab-grown diamond guide explains how the two compare. Compare it with every other outline in our diamond shapes guide, and get to grips with what actually drives price in our diamond 4Cs guide. Each stone is independently graded and openly priced, ready to set into one of our settings or a piece designed from scratch with you.
