SednaTM Gold

OMEGA has been using the exclusive 18K SednaTM Gold, its own fiery rose gold alloy, since 2012. Named after Sedna, an orbiting planetoid that has been described as one of the reddest in the solar system, SednaTM Gold not only bears all the standard characteristics of other 18K golds, but it also offers high resistance to the fading of colour and lustre over time. Its unique composition includes copper and palladium for colour and stability.

Diamonds

Diamond is recognised as the hardest material on Earth, graded 10 on the Mohs hardness scale, and is the only gem made entirely of carbon. In nature, it can only be formed under high temperature and pressure conditions that exist within a specific depth range (~100 miles) beneath the Earth's surface. To decorate its timepieces and jewellery, OMEGA uses "Top Wesselton" white COLOUR diamonds with CLARITY ranging from pure to VVS (Very Very Small inclusions). Along with choosing the best weight in CARAT, the CUT is also carefully selected in order to maximise brightness and scintillation. It goes without saying that OMEGA is a certified member of the non-profit Responsible Jewellery Council (RJC), assuring customers that its processes involving people, materials and the environment are ethical and fair.

Mother-of-pearl

Also known as "nacre", mother-of-pearl is an organic-inorganic composite material produced by some molluscs as an inner shell layer, similar to pearls. It is strong, resilient and iridescent, with changing colours depending on the wavelengths of light at different viewing angles. Produced with exquisite skill and delicacy, OMEGA's ladies' collection offers mother-of-pearl dials of top quality, enhanced with specific attributes.

Sapphire Crystal

To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.
