Description

This CEF philatelic sheet features a carefully designed layout dedicated to the "Nature de France" series, specifically focusing on calcite among minerals. The main part of the sheet includes a detailed explanatory text about calcite, its chemical properties, crystalline forms, and geological importance, all printed in black on a white background.

In the center, an artistic illustration highlights a stylized calcite crystal, in light blue, white, and beige tones, adding a contemporary touch to the whole. The graphic framing of the central image structures the composition and draws the eye to the main subject.

In the lower right corner, a 4.00 French franc stamp is affixed, also depicting calcite, accompanied by a round cancellation bearing the inscription "Nature de France - Minéraux" and the date September 15, 1990, in Paris. The cancellation is clear and well-centered, a detail appreciated in philately.

Did you know? Calcite is one of the most common minerals on Earth and is the main component of limestone and marble. It can form spectacular crystals, sometimes several meters long, and possesses remarkable optical properties, such as birefringence. Its name comes from the Latin "calx," meaning lime.
