![]() ![]() The Ancient Greeks referred to quartz as κρύσταλλος ( krustallos) derived from the Ancient Greek κρύος ( kruos) meaning "icy cold", because some philosophers (including Theophrastus) understood that the mineral to be a form of supercooled ice. The word "quartz" is derived from the German word Quarz, which had the same form in the first half of the 14th century in Middle High German and in East Central German and which came from the Polish dialect term kwardy, which corresponds to the Czech term tvrdý ("hard"). Quartz is the mineral defining the value of 7 on the Mohs scale of hardness, a qualitative scratch method for determining the hardness of a material to abrasion. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. There are many different varieties of quartz, several of which are classified as gemstones. Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. The transformation from α-quartz to β-quartz takes place abruptly at 573 ☌ (846 K 1,063 ☏). Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2. Quartz is a hard, crystalline mineral composed of silica ( silicon dioxide).

Whichever gem you choose, be sure to take care of them. And from the many options, you’re bound to find something to suit you. In all shades, pink gemstones are beautiful.

However, if you can’t tell what color your veins are, your skin tone is neutral. If your veins are green or greenish-blue, your skin tone is warm. If your veins look blue or purple under your skin, you have a cool skin tone. To know your skin tone, view your veins in natural light. Generally, brightly colored gems, like bright pink, favor cool skin tones. Our discussion can’t end without some reflection on what skin tones match pink gemstones. Stones might not scratch easily, but they can break when they strike hard surfaces. Still, the Mohs scale only measures scratch resistance. The higher the number, the more scratch-proof it is. □ Did You Know? Gemstone hardness is measured using the Mohs scale, using numbers 1 to 10. We’re sharing five hot pink gemstones and how often you can wear them based on their durability. In gemstones, this color stands out just as boldly. Hot pink is a brilliant pink shade meant to draw the eye. The heart chakra is one’s center of love for themselves and others.

Instinctively, we all associate the color pink with love, femininity, and compassion. How much do you know about pink gemstones? If you’re interested in gaining more insight into these gems, this post is for you. From the dark shades of rhodolites to the delicate hues of pink corals, we love all the colors the earth has given us. We can say this for pink gemstones as well. Gemstones tell a geologic story of years of mineral consolidation while looking gorgeous. ![]()
