The mala, trengwa, in Tibetan is the Buddhist rosary, the object whose monk (or even the lay practitioner) almost never separates, holding him to the hand or wraps around the wrist. The mala is first of all a utilitarian object: it serves as a tactile support for the recitation of mantras, at the same time as it is used to count them if we have decided to repeat a defined number. THE mala is composed of 108 strung beads, which justifies its name, since it simply means "garland" (of beads). The different components contain each a symbolic meaning specify: The large pearl (or head of Buddha) which closes the circle represents the knowledge of emptiness. The little cone which surmounts it is the mark of emptiness itself. As a gemologist graduated from the National Institute of Gemmology in Paris, all our stones are appraised and certified. As Malakara, we make all of our malas ourselves scrupulously respecting tradition. Mala, Tibetan Buddhist rosary 108 5/5.8mm barrel white nephrite jade beads.

Pure jadeite, NaAlSi2O6, is colorless or white, but if chromium where iron replaces aluminum, the color resulting from this substitution can then be green. This first group of colors is directly related to the structure, and therefore is called the primary group. Secondary colors such as red and yellow, appear when jadeite has been exposed to the earth's surface. Oxidation and hydrolysis lead to the decomposition of the surface and the solutions containing ferric oxide infiltrate jadeite to form limonite and hematite in the intergranular spaces, hence the color yellow or red. As the color group occurs after the crystallization of jadeite, one calls it secondary group. It is also called the "skin color" of the raw jadeite. White jadeite: the composition of white jadeite has a pure chemical composition without ions such as chromium or iron causing the colour. Under the microscope, the crystals appear clean, without alteration chemical. This result is confirmed by X-ray diffraction analysis. Jadeite violet: violet-colored jadeite exists in several tonalities different: pink violet, bluish violet and red violet. In general, jadeite of this color is rather pale. We have long thought that purple jadeite was stained by manganese ions, but no data no convincing analytical support for this view. In 1974, G.R. Rossman suggested that the purple color was due to ferrous transition elements and ferric. This was confirmed by carrying out measurements of the spectrum of the visible light.
