Rainbow Quartz Or Clear Quartz

Is quartz the same as quartzite?

Quartz, in reference to residential and commercial surfaces, is an engineered material. The mineral quartz occurs naturally in a multitude of colors ranging from nearly crystal-clear to jet black and a rainbow of hues between. This mineral is fused with a combination of resins, polymers, pigments and other powdered or ground materials to form an extremely hard, non-porous, durable material.Quartzite is a naturally-occurring metamorphic stone. Millions of years ago, modern-day quartzite countertops began as sandstone. Over time, quartz crystals formed within its spaces and fused together under heat and pressure.Quartzite is harder than granite, so it is quite durable. It withstands heat very well. Quartz is hard too, but not quite as hard as quartzite. The resin used in manufacturing quartz countertops is a plastic, so it is prone to melting in heat above 300 degrees Fahrenheit.Where quartz has an advantage over quartzite is that it is less prone to denting and chipping because it is more flexible. Both countertop materials can be scratched by sharp objects, and a cutting board should be used.\They are same difference between quartz & quartzite .If you need Quartz minerals for your industrial uses then visit : Quartz Powder Manufacturer in India .Anand Talc is one of the best Industrial Minerals Supplier in Rajasthan .More Details about mining minerals ,visit :Talc Powder Suppliers in India

How accurate is the camera test for amethyst and quartz? Is it true that if it comes out blue instead of purple it's probably fake? And if the quartz comes out white instead of pink it's fake also?

Synthetic amethyst can sometimes be distinguished using a loupe. It has waves or color bands on its main axis, but otherwise can be difficult to tell apart from natural. Most quartz is cheap and not worth synthesizing. Amethyst and citrine are the exceptions. Prime “Siberian” amethyst can be pricey.For myself, I think synthetic amethyst appears glassy, too perfect and has a strange rainbow shimmer. Beyond that, amethyst is generally inexpensive except for the magnificent red-purple variety which most of us have never even seen. If you come across this type, it will be expensive and need GIA testing to confirm its validity. Amethyst is grown hydrothermically, so only produced by industrial plants vs “home-growers” for industrial use. I have a few synthetic amethysts in my “Synthetic Collection” that I use for comparisons but one needs a sensitive spectroscope to look for abnormal absorption lines.I have never heard of a camera test and it wouldn’t be reliable anyway. Stones can look very different, even under the same light wavelength depending on the angle and setting. Colors are often not represented naturally in photography as you can tell from your own photographs. The digital age has introduced issues such as white balance and “digital dark rooms”. So, I wouldn’t rely on photography for gem stone diagnosis.

How are crystal singing bowls made? Why is there such a large price difference between frosted singing bowls and clear/colored singing bowls? Are they all made from quartz crystal or are some made from other crystal?

Crystal Singing Bowls are made from 99.992% pure quartz crystal that is crushed and heated to approximately 4000 degrees in a centrifugal mold. The bowls emit a powerful, pure resonance. The thickness of the bowl, as well as the height and diameter, determine the specific vibrational frequency of the bowl.Frosted crystal singing bowls are the most common type of quartz singing bowl. Referred to as frosted bowls, or classic frosted, they represent the original quartz singing bowl. Adopted from the semiconductor industry, they are heavy, rigid and generally uniform. They are called frosted due to the rough exterior, which is a byproduct of the manufacturing process. The surface is the rough sand form of the quartz that is placed in a spinning mold and fused with a hydrogen flame from the inside out. The intense heat and motion combine to recreate the crystal matrix the bowl owes is strength to. The fusion is most evident on the inside of the bowl where the flame has healed a completely smooth surface. Some of the quartz sand is not fused to the bowl and is removed when the bowl has cooled.Clear crystal quartz singing bowls are manufactured using an extreme temperature variation of glass blowing, whereas a pure quartz tube is heated with a 4000 degree hydrogen flame. Pressurized air is used to blow the bowls into shape while rotating them in a mold, the bowl is cut to height and the cut edge is fused smooth with the same hydrogen flame. “Colored” crystal singing bowls are made from gemstones (such as amethyst, smokey quartz, carnelian, citrine, etc.) that are crushed and fused with the basic quartz. The price difference is due to the difference in manufacturing processes as well as the various gemstones used for the specific bowl.

Is moonstone a type of quartz?

Other answers here are correct and very good.I was mistaken.Indeed, moonstone is a variety of orthoclase feldspar. True moonstone can be distinguished from opal (that might be misrepresented as “moonstone”) based on hardness. Moonstone feldspar has a hardness of 6.0–6.5, whereas opal, that might be promoted as a “moonstone”, has a hardness of 5.5–6.0. Difference in hardness is due to the crystal structure, or lack of (“opal” is naturally occurring hydrated amorphous quartz). Opal has many varieties depending on the amount of inclusions and trace elements.Opal that is represented as “moonstone” is a milkish-colored form with a blue tint.Jewels That Play With Light: Mysterious Moonstone, Luminous Labradorite and Scintillating SunstoneHere is a discussion of opal from the Geology Page….Black, Fire, Boulder, Rough, Jelly, CrystalOpalite is a synthetic form of opal….not true opal.I have purchased “moonstone” (in the distant past) that turns out to be opal, and not true orthoclase feldspar.Be aware! I learned my lesson!
