Serene Altar Goddess Clear Quartz and Moonstone

Quartz Crystal system is Trigonal-Hexagonal .

 Trigonal describes a unit cell that looks like an oblique cube - the lengths of all axes are equal, and the angles in the corresponding corners are equal but not rectangular.

 

Although quartz belongs to the trigonal system, its unit cell is hexagonal.
 

 

Clear Quartz is also known as Crystal Quartz or Rock Crystal.

 

It is colourless Quartz, a natural form of silicon dioxide. Silicon dioxide also known as silica, is a natural compound made of two of the earth's most abundant materials: silicon and oxygen. Silicon dioxide is most often recognized in the form of quartz. It's found naturally in water, plants, animals, and the earth. The earth's crust is 59 percent silica.

 

Traditional uses - Quartz traditionally known as the Master Healer,  said to amplify energy by absorbing, storing, releasing, and regulating it. It's also said to aid concentration and memory. Physically, clear crystals are claimed to help stimulate the immune system and balance out your entire body.

Moonstone crystal structure is Monoclinic.
 In the monoclinic system, the crystal is described by vectors of unequal lengths, as in the orthorhombic system. They form a rectangular prism with a parallelogram as its base. Hence two pairs of vectors are perpendicular (meet at right angles), while the third pair makes an angle other than 90°.

 

Moonstone is colourless, very translucent, or almost perfectly transparent feldspar, which in certain direction reflects a bluish, milky light, that has been compared to the light of the moon.

 

Moonstone is a potassium feldspar of the orthoclase species with white shimmer, similar to moonshine (therefore the name), called adularescence. Thin alternating layers of orthoclase and albite create the light interference in this material that is responsible for its "shiller" or "floating moon effect".
