1. There is no difference between the energy levels of a cut and raw crystal (the amount of field emitted). 2. There is a variable difference between the frequency of the field between cut and raw crystals (of the same type). We tested further and found the difference was between 0 and 12%.

The main difference is definitely the colors they show when hit with light. Labradorite is a dark grey, black crystal. It shows a multitude of wonderful colors such as yellow, green, purple, red, or blue when you look at it under the light. Moonstone, on the other hand, is usually white, peach, green, pink, or blue.

If you want to know how to tell the difference between Amethyst and Purple Fluorite, look for bands in the stone. Purple Fluorite often exhibits bands of varying shades, while Amethyst tends to have a more uniform color with possible inclusions or zones. Fluorite grows in cubical shapes, whereas Amethyst often occurs in six-sided prisms.

Rose quartz is typically fairly uniformly coloured. Rose quartz is muddy, suggesting the presence of phase 2, pink-coloured fibre inclusions. Pink quartz refers to quartz single crystals with a similar rose tint. Pink quartz is photo-catalytically unstable, and unlike giant rose quartz, it is exceedingly uncommon.

Talc has a score of 1, and gypsum has a score of 2, which makes these two minerals similar and difficult to differentiate between. Feel both pieces of rock for how slippery they are. If the rock is slippery, it may be talc. If the rock isn't slippery it may be gypsum. Fragment pieces of each rock with your fingernail.

Beakers are the workhorse glassware of any chemistry lab. They come in a variety of sizes and are used for measuring volumes of liquid. Beakers aren't particularly precise. Some aren't even marked with volume measurements. A typical beaker is accurate within about 10%. In other words, a 250-ml beaker will hold 250 ml +/- 25 ml of liquid.

Remove the tubing from the heat and allow it to cool a couple of seconds. In a single motion, bend the slightly cooled glass to the desired angle.

It's fairly easy to tell the difference. First, look at the color. Amethyst will almost be a pure purple, whereas fluorite, as mentioned, will have a variety of colors, which can come in patches. If most of the fluorite is purple, pay close attention to patches and see if you see any different colors, even if it's subtle.

Quartz is the second most abundant mineral on Earth. Quartz and amethyst are almost identical in physical properties. The only difference between quartz and amethyst is color. When quartz has shades of purple, it is amethyst. If quartz minerals aren't purple, it is not amethyst, but it may be a different type of semi-precious stone.

Quartz, for example, will form six-sided prisms with pointed ends (Figure 2.6.4a), but this typically happens only when it crystallizes from a hot water solution within a cavity in an existing rock. Pyrite can form cubic crystals (Figure 2.6.4b), but can also form crystals with 12 faces, known as dodecahedra ("dodeca" means 12). The mineral ...

The amethyst should be at least as hard as real quartz, if not harder. On the Mohs scale, minerals are ranked by how hard they are. Amethyst has a Mohs hardness of 7, meaning it can scratch steel and glass, but minerals like diamonds can. You can use a Mohs hardness kit, but be careful because it can damage the stone.

One of the most important thermal properties of fused quartz is its extremely low coefficient of thermal expansion: 5.5 x 10 -7 /°C (20-320 °C). Its coefficient is 1/34 that of copper and only 1/7 of borosilicate glass. This makes the material particularly useful for optical flats, mirrors, furnace windows and critical optical applications ...
