The paper describes the formal establishment of the paulkerrite group of minerals and its nomenclature. It includes the application of a site-merging procedure, coupled with a site-total-charge analysis, to obtain unambiguous end-member formulae. Application of the procedure has resulted in the revision of the end-member formulae for several of the group members.

Elba tourmaline crystals commonly display a sharp transition to dark colors at the analogous termination, but the mechanisms leading to the formation of such terminations are unclear. Here we propose a general genetic model in which, as a consequence of a pocket rupture event, chemical alteration of early formed Fe-/Mn-rich minerals in the enclosing pegmatite was responsible for the release of Fe and/or Mn in the geochemical system, allowing the formation of the late-stage dark terminations.

We report the description and the characterization of a new mineral species, found in a rock sample from the geological formation called the Pilanesberg Complex, South Africa. This is a silicate mineral that contains a significant amount of sodium, calcium, iron, titanium and fluorine. Its atomic structure shows that it is related to other wöhlerite-group minerals. This work provides new insights into the crystallization conditions that ruled the formation of the Pilanesberg complex.

Short summary
There are unresolved problems related to the nomenclature and identification of mineral species belonging to the triphylite group of minerals. They can be solved by discarding the traditional views on succession of mineral species during oxidation. In other words, it is necessary to separate the concepts of the origin of the mineral and the boundaries of the species.

A reinvestigation of angastonite from the type locality has shown that it is a mixture of crystalline phases and an amorphous phase, with the published formula corresponding to the amorphous phase. A redefinition proposal for angastonite as an amorphous mineral was approved by the IMA CNMNC. Our study showed how the amorphous phase formed and how it progressively recrystallises as new crandallite-related minerals.

The reliquary crown, hosted in the diocesan museum of Namur (Belgium), was produced during the beginning of the 13th century. This beautiful piece of goldsmithery is decorated with approximately 400 pearls and coloured stones which were investigated by Raman and pXRF techniques. Emeralds, pink spinels, sapphires, almandine garnets, turquoises, and pearls were identified. The gemstones, contemporary with the crown, probably arrived in Europe by the silk trade road.

Luxembourgite, ideally AgCuPbBi4Se8, is a new selenide discovered at Bivels, Grand Duchy of Luxembourg. The mineral forms tiny fibres deposited on dolomite crystals. Its crystal structure is similar to those of litochlebite and watkinsonite, and can be described as an alternation of two types of anionic layers: a pseudotetragonal layer four atoms thick and a pseudohexagonal layer one atom thick. The species named for the city of Luxembourg, close to its locality of discovery.
