Rubies, the birthstone of July, are considered the king of gems and represent love, health and wisdom. It was believed wearing a fine red Ruby bestowed good fortune on its owner. A Ruby is the most valuable gemstone and its value increases based on its color and quality.
Geological information:
A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium. Its name comes from ruber, Latin for red. Other varieties of gem-quality corundum are called sapphires. Ruby is considered one of the four precious stones, together with sapphire, emerald and diamond.


Peridot, the birthstone of August, carries a lime green color and is one of only a few gemstones that exists in only one color. Peridot is believed to instill power and influence as well as bring the wearer magical powers and properties that protect against nightmares
Geological information:
Peridot is gem-quality olivine. Olivine is a silicate mineral with the formula of (Mg, Fe)2SiO4. As peridot is the magnesium-rich variety (forsterite) the formula approaches Mg2SiO4.


Sapphire, the birthstone of September, is most desired in its pure, rich blue color but is present in almost every color including pink, yellow and green. In the Middle Ages the gem was believed to protect those close to you from harm and also represented loyalty and trust
Geological information: 
Sapphire is a typically blue gemstone variety of the mineral corundum, an aluminium oxide (α-Al2O3). Trace amounts of elements such as iron, titanium, chromium, copper, or magnesium can give corundum respectively blue, yellow, purple, orange, or green color. Chromium impurities in corundum yield pink or red tint, the latter being called ruby.
 Formula: Al2O3
System: Trigonal
Hardness: 9


October also has two birthstones; Tourmaline and Opal. Tourmaline is a favorite gemstone for many because it’s available in a rainbow of beautiful colors. Opal gemstones are truly unique because each individual gem is adorned with a one-of-a-kind color combination
Geological information:
Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone comes in a wide variety of colors.

Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike the other crystalline forms of silica, which are classed as minerals. It is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl, and basalt. Opal is the national gemstone of Australia.


November birthdays is Topaz symbolizes love and affection, and is said to bestow strength and intelligence on the person who wears it, according to the Old Farmer’s Almanac, and a gift of blue topaz is said to be a promise of love and fidelity.
Geological information:
Topaz is a silicate mineral of aluminium and fluorine with the chemical formula Al2SiO4(F,OH)2. Topaz crystallizes in the orthorhombic system, and its crystals are mostly prismatic terminated by pyramidal and other faces.


December birthdays are; Zircon, and Turquoise. Each of these gemstones carries a unique blue tone making it a perfect birthstone for Minnesota’s frigid December winters. Zircon can be found in a variety of colors, but blue is the overwhelming favorite.
Geological information:
Zircon is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is ZrSiO4. The crystal structure of zircon is tetragonal crystal system. The natural color of zircon varies between colorless, yellow-golden, red, brown, blue, and green. Colorless specimens that show gem quality are a popular substitute for diamond and are also known as "Matura diamond".
Turquoise is an opaque, blue-to-green mineral that is a hydrated phosphate of copper and aluminium, with the chemical formula CuAl6(PO4)4(OH)8·4H2O. It is rare and valuable in finer grades and has been prized as a gem and ornamental stone for thousands of years owing to its unique hue. In recent times, turquoise, like most other opaque gems, has been devalued by the introduction of treatments, imitations, and synthetics onto the market.
