Giallo Fiorito granite

Description of colouring and granulometry: coarse-grained and homogeneous granite of an ochre-yellow colour, often
mistaken for Venetian Yellow. The most noticeable element is the orthoclase-feldspar which measures up to 8 cm in size.
The centre of the crystals is always lighter, ranging between ivory and beige-grey, while towards the outside it changes to a
deep ochre-brown colour. For the most part this rock is scattered with black biotite and it contains large crystals. There are
also smaller-grained quartz crystals of a light to transparent grey colour and biotite, which fills the empty spaces. The yellow
colour of this light stone derives from the chemical disaggregation typical of tropical zones. It is quarried in the state of Minas
Gerais.
