quartz
A very hard, widespread mineral made of silicon dioxide. Quartz is used in many areas because of its piezoelectric properties and hardness, for example in watches (quartz watches), electronics, and jewelry making.
In den Alpen kann man mit etwas Glück Kristalle aus reinem Quarz finden.
In the Alps, with a bit of luck, you can find crystals made of pure quartz.
'Quarz' (quartz) is the base word in many compound nouns, especially in the fields of technology and geology. If you see 'Quarz-' at the beginning of a word, it often refers to the mineral or its properties.
Meine erste Uhr war eine einfache Quarzuhr.
My first watch was a simple quartz watch.
'Quarz' (quartz) is often described with adjectives that emphasize its properties, such as 'hart' (hard), 'rein' (pure), or 'kristallin' (crystalline). In geological contexts, you often find the phrasing 'besteht aus Quarz' (consists of quartz) or 'enthält Quarz' (contains quartz).
Dieser Stein besteht fast vollständig aus reinem Quarz.
This stone consists almost entirely of pure quartz.
Although 'Quarz' (quartz) is a technical term from mineralogy, the word is also very well known in everyday language through products such as the 'Quarzuhr' (quartz watch). So it is used in both scientific and everyday contexts.
In vielen elektronischen Geräten werden Quarzkristalle wegen ihrer präzisen Schwingungen verbaut.
In many electronic devices, quartz crystals are installed because of their precise oscillations.

'der Kristall' and 'der Quarz' can both have to do with minerals and clear, solid forms. 'Kristall' generally describes a solid body with a regular internal structure and often clear surfaces. 'Quarz' is a specific mineral that can itself form crystals. The words can be confused because quartz often occurs as a crystal. But not every crystal is quartz. If you mean the form or structure, 'Kristall' fits. If you mean the specific mineral, 'Quarz' is more precise.
Paula hat im Park einen hellen Stein gefunden, der wie Quarz aussieht.
