OnixTM is a blood orange with a skin that is an extraordinarily deeply coloured dark red-purple, almost black. 60% of the fruit on a tree are coloured in this way, while 40% have striking red chimeras across the surface of the skin. The smooth skin, which has a pink albedo, is fairly easily removed, though can be quite thick. The fruit is round-oval in shape.

The segments are striated with red pigmentation and have a high red juice content of about 50%. The taste is well balanced and aromatic, with acidity giving a tangy experience, particularly in the early season. The balancing sweetness comes from brix levels of 11.7 to 13o.

Onix is essentially a Sanguinelli with more intensity of pigmentation and therefore a greater anthocyanin content, though otherwise very similar.

The tree was growing in a lowland area, near the Guadalquivir River, on loose-textured soils with a Mediterranean climate of mild winters and warm summers.
