CUARZO ROSA

La mina de Cuarzo rosa ALBA II (Cáceres) fue descubierta por el geólogo D. Jesús Balmaseda Guerrero en 1967. Está considerada como el mejor yacimiento de  cuarzo rosa del mundo por la calidad de sus gemas y su volumen. ALBA está situada en armonía natural con el escenario idílico de Extremadura.La mina ALBA II produce las mejores gemas de cuarzo rosa del mundo con las que diseñamos nuestras joyas 

Rose quartz is a gemstone color.
Quartz belongs to the group, macro lens, the system is trigonal (rhombohedral) in its network crystallographic differences depending on the deposit and the origin of the mineral, which determines the intensity of color and transparency of gem and hence their quality, that is, the more intensity of color, transparency and brightness have the gem, the greater its value more exclusive.

Usually appear within the small gems inclusions of rutile needles in the carved cabochon is the phenomenon of di asterism (stars of light of six points) for the reflection of light, conveying a great beauty and radiance to properly cut pieces as is the case of our PM MIBA

Currently there are three known deposits rose quartz, rose quartz there are indications in the U.S., Namibia and Mozambique, but now there are only three deposits rose quartz mined in the world, located in Brazil, Madagascar and Spain .

However, there are important differences between these sites, both geological and physicochemical determinants of gem quality, so depending on the origin of the gem, have characteristics other than color, transparency and brightness. The differences between quartz gems are significant both in the crystallographic network as at first sight, since it determines the fundamental characteristics of any precious stone. The fundamental difference between quartz Spanish, Brazilian and African ions lies in the crystallographic network component.

The color of rose quartz has been the subject of numerous studies having been agreed in their conclusions the authors of them, some attribute to the presence of iron and manganese ions. Recently it has raised the possibility that the color is due to the presence of lithium
 

MIBA S.A with geologist Don. Balmaseda Guerrero in front Jesus has studied and researched in the past 30 years rose quartz from its origin, geology (formation, genesis, the site ... etc.) To the physical and chemical characteristics of our rose quartz and has been compared to Brazilian and African samples reaching interesting conclusions such as rose quartz show that our MIBA not lose color over time, unlike what happens with Brazilian and African samples and that these gems do not have the brightness of rose quartz MIBA

If differences in the scope of its membership are significant, at a glance you can see more differences, including determining the origin of rose quartz gem. MIBA rose quartz is superior in both color and intensity trasparecia.

ALBA gem deposits were discovered in 1967 by Balmaseda d Jesus Guerrero, a geologist by profession who, from his discovery and for over 30 years conducted research on such deposits by one of the most comprehensive studies are known about the geology of rose quartz The sites are located on the border southwest of the granitic massif de Gredos, and more specifically as part of pegmatitic formations embedded in a formation of two-mica porphyritic granite, with biotite, quartz and plagioclase, in large prismatic crystals, the major minerals appear muscovite as accessory The predominant directions of the outcrop is n 15 °, n 30 ° n 60 ° The average power of the veins of quartz is 3.5 meters (size of the reef), ranging between 50 cm and 8 m is a case exceptional in gemology in the opinion of one expert in gemology with more world-class reputation, Dr. Yan Canis who actively collaborates with Mr. Balmaseda in the investigation of yacimiento.Miba The Jewelry Rose Quartz Heart of Spain ...
