Weight choice from 05-10g to 20-30g Shapes and colors vary from one stone to another Contrary to popular belief, the name citrine comes from the Latin "citrus," which does not refer to "lemon" but to the yellow citrus fruits of the citron tree. Moreover, citron tree comes from the Greek word "kédros," meaning cedar. This Latin root is found in the names lemon, lemon tree, or lemongrass, but also in pumpkin or citraire (an old name for lemon balm producing a yellow-colored infusion). Long before being attributed to the citrine stone, the terms citrin and citrine described color adjectives. In very old medical books, writings mention "citrine" ointments or "citrin" balms. Nowadays, there are two types of citrines available on the market, either natural citrine or heated citrine. Citrine is a quartz and belongs to the silicate group, more precisely the tectosilicates with a hexagonal crystal system. It has a hardness of 7/10 on the Mohs scale, indicating that it has good chemical and mechanical resistance. In summary, citrine is a stone from the same family as rock crystal and amethyst. The only difference is in their respective colors. It should be noted that rock crystal is pure silicon dioxide, whereas citrine contains iron inclusions, giving it its yellow color when naturally heated by magma. Thus, to obtain heated citrine, amethyst is quickly heated between 500 and 600°C. Its color under the effect of heat will vary from purple to yellow. The iron and aluminum atoms change until they give a bright yellow color. It is exactly the same process for natural citrine, except that the heating process caused by magma takes place over decades. It is evident that natural citrine has a much higher cost than that of industrially heated citrine. Heated citrine has a very yellow color, darker, less translucent, or even opaque compared to natural citrine. The majority of citrines on the market are actually heated citrines. They have inclusions, water pockets containing minerals trapped in the stone and growing inside. In the natural environment, these water pockets do not cause any fractures. But heated industrially and quickly, they form fractures.
