Pentagonal Natural 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. These are natural stones, formed over billions of years and mined under traceable, conflict-free supply chains. Read what makes a diamond ethical before you choose. 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. All our stones carry independent laboratory certification and transparent pricing, and our London team will talk you through any of them with no obligation.
