The Bastion Quad Pendant

The Bastion Quad Pendant distills fine jewelry into pure structural geometry. Engineered with a compact 10.50mm footprint, this design creates high-impact presence through sharp contrast—framing the bold, right-angle architecture of a square gemstone with four brilliant diamonds resting at the cardinal axis.

At the core is a calibrated 3.50mm square Australian sapphire, available across the complete geological spectrum: Teal, Green, Blue, Yellow. Held firmly within geometric corner brackets, the sapphire catches direct daylight from all four flanks, while the surrounding diamond accents deliver a continuous halo of white fire. It is an everyday signature piece built with clean lines and balanced proportions.
