This page gathers every gemstone in our collection cut to a square outline — a geometry that includes step-cut squares in the emerald and Asscher manner, square brilliants, and softly rounded square cushions. Square cuts are chosen for their symmetry and their architectural presence: they sit cleanly in bezels, channel rows and signet-style mounts, and they tile neatly beside one another in bands and cluster work.
The varieties represented here are Aquamarine, Tanzanite, and Tourmaline in green, pink and mixed colour expressions. These are all stones whose colour reads particularly well across a broad, flat table, which is why they appear so often in square form. Step cuts emphasise body colour in long, calm flashes; square brilliants and cushions break light into more scintillation.
When choosing, weigh three things. First, the faceting style, since it governs whether you want depth of colour or liveliness. Second, pleochroism — aquamarine, tanzanite and tourmaline all show slightly different hues along different crystal directions, so orientation affects the face-up colour. Third, the corners: square stones have four vulnerable points, best protected by a bezel or well-formed claws.
