En lithothérapie et en méditation, la brookite a une action intense lorsqu'elle est utilisée au chakra du 3e oeil.Elle attire et retient les énergies, active le sixième et le septième chakra ainsi que le chakra ethérique, le 8e chakra, situé au-dessus de la tête permettant ainsi d'explorer les royaumes subtils avec une conscience sensible et stable.

Brookite has over the limit (OTL) refractive indices of 2.583-2.740. This gem shares some properties with another rarely faceted mineral, rutile. These fellow polymorphs have overlapping ranges of color and refractive index (RI). Nevertheless, rutiles usually have uniaxial optic character while brookites have biaxial.

Anatase and brookite have been converted in opposed-anvil high pressure apparatus to a new phase, TiO 2-II, which has the αPbO 2 structure. Starting with anatase and II, or brookite and II, p–T reaction boundaries were obtained which yield apparent triple points among the polymorphs anatase-II-rutile and brookite-II-rutile in the region of 480°C and …

Comme l'anatase, elle est typique du contexte des "fentes alpines". La Brookite est également connue dans certaines pegmatites et quelques skarns. On la retrouve évidemment dans les alluvions. Les cristaux sont fréquents, ils sont le plus souvent tabulaires à lamellaires, avec présence des stries dans le sens de l'allongement.

Occurrence in Wales: brookite is justifiably a famous Welsh mineral, as both the type material and some of the world's finest crystals come from the hills of Snowdonia. J. Sowerby, in volume III of his book 'British Mineralogy' (1809), figured 'oxide of titanium': this is a brookite specimen that was collected from 'near Snowdon' by Wilson Lowry, and is …

This is especially true at Magnet Cove. Some serious mineral collecting of the area took place before the 20th century, but most collecting has gone on during the 1930's through the 1990's. Mining of rutile, though short lived in the early 1940's, provided an area that was accessible for 40 years to collectors.
