Quartz

Properties

Pink or smoked quartz, purple amethyst, green amethyst, citrine… They are gems that share a great similarity in their chemical composition and, together, make up the so-called quartz group. Quartz is pure silica, which constitutes approximately 60% of the earth’s crust: the sandy beach upon which we sit on holiday while the children build sand castles is quartz, as are the desert sands of the world. Pink quartz obtains this tonality due to its composition in phosphorus and it is associated with unconditional love and peace.

Purple amethyst is the most appreciated stone in this group. It has been attributed supernatural properties: it is protective and gives luck and stability.

Tres ametistes liles, dos amb talla oval i una amb talla maragda, llueixen els seus tons liles. Jordi Rosich les utilitza en les seves col·leccions de joieria, sovint de la col·lecció Blossom en la que les gemmes naturals són les protagonistes.

We can find amethysts of other colors because of the calcination process at high temperatures: yellow, clear, red, green or colorless.

Citrine is considered the amethyst’s son and, in the Ancient times, it represented the consciousness of spiritual masters.

Smoked quartz obtains this chromaticity thanks to its exposure to temperatures between 300º and 400º.
