I recently bought a 22-gram morganite rough from an antique market. Morganite is a beryl*, the same class of mineral as its much more famous green variety (emeralds) and blue variety (aquamarines). Unlike emeralds and aquamarines, the pale, very slightly purplish pink morganites are not expensive. This 110-carat rough only cost me CAD $20 (USD $15, EUR 14, GBP 11.80).
* Beryl is a mineral composed of beryllium aluminium cyclosilicate with the chemical formula Be3Al2(Si O3)6.
By the way, morganite was named after John Pierpoint ( J.P. ) Morgan the well-known banker. Mr. Morgan was an avid gemstone collector and close friend of gemologist George Kunz. When the pink beryl was first discovered in Madagascar in 1910, Mr. Kunz proposed the name morganite at a meeting of the New York Academy of Sciences on 5 December 1910 to honor his friend and customer J.P. Morgan.
Recent corals used fo a necklace, baught at a jumble sale. It is not good to make jewellery out of this rare corals.
If you believe in superstition, they are a good apotropaic device against the evil eye!
Rubellite tourmaline (~1 centimeter across at its widest; 2.25 carats)
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5900 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The silicates are the most abundant and chemically complex group of minerals. All silicates have silica as the basis for their chemistry. "Silica" refers to SiO2 chemistry. The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4. Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens "belong" to each silicon. The resulting formula for silica is thus SiO2, not SiO4.
Tourmaline is a classic "garbage-can mineral" - it has a little bit of just about everything. Tourmaline can be given the formula (Na,Ca)(Li,Mg,Al)(Fe,Mn,Al)6(BO3)3(Si6O18)(OH,F)4 - sodium calcium lithium magnesium iron manganese hydroxy-fluoro-boro-aluminosilicate. Tourmaline has a nonmetallic luster, varies in color but is often blackish, has a white streak, is quite hard (H = 7 to 7.5), frequently has elongated crystals with rounded triangular cross-sections and striated faces, no cleavage, and conchoidal fracture.
Tourmaline is a group of minerals, the most common of which is the blackish-colored, Fe-rich schorl (see elsewhere in this photo album). Dark brown, Mg-rich dravite is another moderately common variety of tourmaline. Other varieties include achroite, elbaite (Li and Na-rich), indicolite, liddicoatite (Li and Ca-rich), rubellite, verdelite, and others. The latter-listed tourmalines are often richly colored (greenish, yellowish, reddish, pinkish, bluish, multicolored).
Tourmaline is moderately common in pegmatites and some metamorphic rocks. It can even be rock-forming - see the scarce rock tourmalinite (www.flickr.com/photos/jsjgeology/15095512541).
The faceted gemstone seen here is rubellite tourmaline, a sodium lithium hydroxy-boro-aluminosilicate - Na(Li,Al)3Al6(BO3)3Si6O18(OH)4.

For bokeh Tuesday I decided to color things up a bit with amber, amethyst and peridot, all from Arizona. And the reflection is a bonus.
s.s., genuine seaglass, turmaline gemstones.

I have been writing some short quotes down on a few of my last posts...I would like to put them all together on this one. ....
Happiness keeps you sweet,
Trials keep you strong,
Sorrows keep you human,
Failures keep you humble,
Success keeps you growing. ~ I am unsure of who wrote each saying but put together..well..thought provoking to me~
Growing day by day...Some learn fast, some learn slow, some learn by trial and error, some by watch and listening. But the catch is to keep trying, keep growing and to know that as long as you are moving and dreaming, you may be growing..at YOUR pace alone. ~Me~
Have a great Sunday evening and Monday morn! Blessings, Andrea
New plants:
I bougt some other species of Lithops at the gardening store to fill up two spare pots that remained empty after the spider mite infestation losses. I cleaned the plants thoroughly before potting them because I do not want to possibly introduce new plant pests. The big round ones are amazing, I never saw them before.
Lithops are extremely succulent plants originating from the semi-deserts of southern Africa. Their plant body rests under ground, while on top they have transparent windows to let sunlight in for photosynthesis. A camouflage pattern on the windows lets them appear more or less like a pair of pebblestones, so hungry animals may hardly find them. I like them because they look like ornamented knobs or gemstones.
DO NOT MISS:
Be aware that sites from the southern hemisphere
have a six-month-shift in the description of the
annual lithops growing cycle.
When an inclusion transform a translucent quartz in a striking and rare gemstone...From Minas Gerais State, Brazil. Polished in Sao Paulo
My friend Pamela gave me a bag of tiny polished gemstones and said "I bet you can do something with these" so I made this Gemstone Jar for her. Repurposed Artichoke jar, black ball chain, polished gemstones.
The Destroyer-Bot is a collaboration between myself and jewelry designer Karin Jacobson. I designed the robot and packaging and she carved the wax master for duplication and set the gemstones. We made only 22 of these and they are for sale here.
