Here again, sugar's chemical construction was instrumental to the outcome. The molten sugar was flung so forcefully and cooled so rapidly that the molecules didn't have time to reorganize as crystals. Cotton candy, like caramel and toffee, is thus called a noncrystalline candy. Fairy floss was...
The Wulfenite crystals in the central part of the piece are relatively large, averaging under a centimeter, however, the crystals on the two sloping edges of the specimen are big and vary in size from 1 and 1.5 cm and show subtle "sandwich" zoning that this locality is known for. These ...
Other varieties that form macroscopic (large enough to see) crystals are: Amethyst, Rock Crystal (clear Quartz), Rose Quartz, and Smoky Quartz. Citrine is the secondary birthstone for November; Topaz being the primary. General Information: *Chemistry: SiO2, Silicon dioxide with colloidal iron ...
large miniature piece from THE- famous Red Cloud Mine in Arizona. The main cluster of crystals, on this piece consists of several unusually robust, thick, tabular crystals in stacked parallel growth and is 3 cm across - they stand right up off the matrix!
Overview: A deserted quarrying area on the south side of SR 443 has recently become known as a site to find abundant small quartz crystals. I decided to visit it myself recently (June 2020) and I very quickly was able to open several pockets of quartz. It’s a great spot to learn ...
As fibrous crystals grow outward from these seeds, newly formed spheres overlap with one another to creating a “grape-like” appearance [33]. This botryoidal habit is a notable example of nodular (domainal) nephrite. Some botryoidal specimens from Washington State are primarily composed of ...

Beryls are a family of gemstone that includeemerald,aquamarine, beryl (green), red, morganite (yellow), and heliodor (pink). Beryl has ahardnessof 7 - 8, aspecific gravityof 2.6 - 2.9, and the chemical formula Be3Al2SiO6. Internal flaws in beryl gems can be hidden by treating the st...
Prospecting for Gemstones and Mineralsis a perfect primer to understanding where to find rocks. Deposits are explained, how to find them, what is inside of them, and how you can get crystals out of the ground. This book serves as a primer to all topics on the subject of rockhounding. ...
