Platinum is heavier and denser than gold (density approx. 21.4 g/cm³ compared to gold's 19.3 g/cm³), which means a platinum piece of jewelry feels noticeably heavier in the hand. The metal is naturally white and retains its luster virtually forever without needing rhodium plating – unlike white gold, whose rhodium coating wears away over time.

Platinum is extremely hard and durable, making it the ideal material for diamond settings – the prongs hold the stone more securely and platinum doesn't wear down in the same way as gold. It is also hypoallergenic and rarely irritates sensitive skin.

Common stamps: '950Pt', '900Pt', 'Pt950', 'Plat', or simply 'Pt'. Pieces with less than 850 parts per thousand platinum may generally not be called platinum in Europe.

Palladium belongs to the platinum group metals (PGM) and shares many of platinum's properties – naturally white color, high corrosion resistance, and hypoallergenic qualities – but is significantly lighter (density approx. 12.0 g/cm³). This makes palladium popular for jewelry that should feel light and comfortable to wear.

Palladium is widely used as an alloy metal in white gold (palladium white gold requires no rhodium plating at all), but pure palladium jewelry (stamped '950Pd' or 'Pd') has become increasingly common since the metal gained official precious metal status in many countries.

Palladium's price history is notably volatile – it was long cheaper than gold, surged dramatically to record highs around 2021 (partly driven by automotive industry demand for catalytic converters), and has since stabilized. We always pay the current market price.
