Aquamarine Harrat Kishb Mecca area

Cone volcanic No. 5 (V-5): a volcanic cone ranging dimensions 600 m north - south and 400 meters east-west and features Alschoria rocks at this site strongly cohesion and thus difficult to extract granules Aquamarine from the wall of the cone volcanic but can get Aquamarine from the vicinity of the cone grit Volcanic which contain mostly on Slater and gravel from basalt rocks and Mnakdat peridotite and Alberoudiat covering this Brush of grit an area of ​​1.4 km X 1.2 km, have been drilled risk trial work on this site to estimate the reserve The results indicate that the cubic meter of gravel materials containing 7.2 grams of aquamarine.
Cone volcanic No. 100 (V-100): This is called the site by the people of the region Mount Thelman and found stones Aquamarine at the top of the mountain, and specifically in the northern part of it, during the exploration operations by helicopters plane Because of the difficulty of access to the site by car have not been studies Rated enough to preliminary evidence indicates the existence of aquamarine stones with high quality and large crystal sizes.
Cone volcanic No. 27 (V-27): it is called Mount Alskhyeerh It is located within the square Mount Abu Arish near Mount Samar and in this region have been found stones Aquamarine in two locations adjacent two cone volcanic southern The dimensions 200 m north - south and 500 meters east - west The volcanic cone North, which has a nominally 400 m north-south and 200 meters east-west and granules can be drawn from neighboring Aquamarine grit of these cones.
I have been an initial reserve estimate these sites by drilling test, according to results the presence of 37 g per cubic meter in Aquamarine and this is the best result to be reached, which refers to the economic viability of the site and exploitation.

Agate arboreal of injustice by the Riyadh region

There are other types of Garnet Garnet Moss Agate mossy stone and mocha Mocha stone, which is a brown onyx and brings from Yemen. The Shrike Sard onyx Agate which is characterized by the existence of the structure and yellow belts.
And Alavintoren Aventurine is a rock mutant consists mainly of quartz (quartzite) and has a Jamaica green oligo which is similar to stone hard green and difficult to distinguish between them and uses Alovintoren in the work of sculpture and decorative purposes and some call it the Indian hard name and must not be confused with the Red Alovintoren which is a metal Alpaat a metal plagioclase Alsoda green Alavintoren.
When quartz inside the crystalline structure contains the same distinctive directing fibers which take a preferred direction results in this structure glitter variable Chatoyancy reflected from the top of the stone surface so when you cut manner Kabshon Cabochon The reason for the emergence of stone this appearance to false for quartz shape and who replaced metal Rabikit Riebeckite.
India is the main source of green stones Alavintoren and followed all of the Soviet Union, Brazil, Australia and finally Germany.
Alavintoren and semi-precious stone ranks of cheap stones and inexpensive price.
