Six Types of Garnet:
Almandine:
Almandine is the most common Garnet. Magnesium occurs within it rather than the iron that is found within pyropes. Almandine range in color from dark red to black, often being cut with a convex face.
Pyrope:
Pyrope is the only member of the Garnet family to always display a red coloration when rough. Pyrope is also noted for its transparency and frequent lack of flaws or inclusions. The origin of most pyrope is in ultramafic rocks, typically peridotite from the mantle. Pyrope has two varieties, rhodolite and malaia. Rhodolite is the purple variety of pyrope while the malaia is the red-orange variety.
Spessartine:
Spessartine is an orange to red form of Garnet. It occurs most often in granite pegmatite and allied rock types. Spessartine, like the other Garnets, occurs as a blend with other species.
Andradite:
Andradite is a calcium-iron Garnet and has a large range of coloration. It can be red, yellow, brown, green or black. It is known as the most lustrous of Garnets and has several varieties. Melanite is the lustrous, opaque black or very dark red variety. Demantoid is the olive-green to emerald-green variety. And Topazolite is the yellow to brownish-yellow variety of Andradite.
Grossular:
Grossular Garnet is the most varicolored of the Garnets. Pure Grossular is colorless, and its wide range of colors is caused by various impurities. Hessonite is an orange to orange-brown variety, Hydrogrossular is a green, pink, grayish-white to bluish variety, chrome grossular is a green variety of grossular. Tsavorite is a dark green variety, while Mali is a yellow-green variety that has a slight overlap in the grossular-andradite series.
Uvarovite:
Uvarovite is the rarest of the familiar Garnets and is hardly ever used as a gem. It is a calcium chromium Garnet with a unique deep chrome-green. It is the only Garnet that comes in one color.
Six Types of Beryl:
Aquamarine:
Aquamarine is a light bluish green form of Beryl. Its color comes for impurities made from iron within the beryl itself. The exact color of the aquamarine is dependent on where the impurities are located within it. Pure blue Aquamarine is the most sought-after version of the gem. A deep blue version of aquamarine also exists, known as Maxixe. Its color turns to white when exposed to sunlight or heat treatment.
Bixbite:
Red Beryl, known as Bixbite, is an extremely rare variety of beryl that gains its red color from trace amounts of manganese. The only crystals of Bixbite suitable for cutting are found in one single location, the Wah Wah Mountains of Beaver County, Utah. It is estimated that one crystal of Bixbite is found for every 150,000 gem-quality diamonds cut.
Emerald:
Emerald is the green variety of beryl, its color coming from traces of the element chromium or vanadium. It is also the most precious and valuable of all 6 types of beryl. Its intense green color has made it very important throughout the centuries. When beryl is light green, it is not known as Emeralds, but rather Green Beryl. A rare type of Emerald known as a Trapiche Emerald is sometimes found where carbon impurities create raylike spokes to give the Emerald a six-pointed radial pattern.
Goshenite:
Goshenite is simply a colorless beryl discovered in Goshen, Massachusetts. It is possible that Goshenite has no impurities, giving it a flawless white/clear appearance, but this isn’t always true as there are several elements that inhibits color in beryl. It also has a very low value.
Heliodor:
Golden Beryl ranges in colors from pale yellow to a brilliant gold. Heliodor is the name used for the light green, orange, and brown colored beryls. Often Golden Beryl and Heliodor is interchangeable despite the differences in colors.
Morganite:
Morganite is known as the pink beryl. It has a rare light pink to rose coloration. Orange and yellow varieties of Morganite can be found and banding of both pink and orange is common. It is routinely heat treated to remove patches of yellow and occasionally irradiation treated to improve its color.

Daily Gem: UNAKITE! Unakite is a coarse granite like rock that contains both PINK orthoclase and pistacio-GREEN epidote. Unakite was named after the Unaka mountains of North Carolina where it was first discovered. It has a mossy like appearance, especially when in its rough gem form. It has a Mohs Hardness of 6-7, close to the hardness of agates and quartzes! UNAKITE is a metamorphic rock, forming when granite is altered by hydro-thermal activity where plagioclase in granite are replaced by epidote, creating the PINK orthoclase and GREEN epidote coloration found in unakite. Unakite is a gem of new beginnings and living in the now, infusing its wearer with powerful vibes to let go of the past and move forward, bringing positivity, & reminding the user to enjoy the little things in life. Unakite is known to free the wearer from thoughts of helplessness and dream-crushing vibes, letting them live life to the fullest.
Daily Gem: AMMOLITE! Ammolite is an organic opal-like gemstone made of the fossilized shells of ammonites! It has a Mohs Hardness of 3.5-4, making it rather soft. It comes in a variety of colors, but the most typical coloration is orange, green, and red. Its brilliance and colors often rival the more subtle coloration found in opal and labradorite. Ammolite is the trade name of the thin aragonite shell of ammonite fossils, but it is also just called ammonite at times. Often, clear quartz or spinel is used as a cover when made into jewelry as it is very fragile, and a shale backing is also used to give it stability. Ammolite is known as the “absorber of knowledge” and therefore enhances wisdom, increases wealth. It is also known to balance negative energy, bringing harmony, increased vitality and luck. Physically, ammolite increases stamina, relieves trauma, alleviate depression, and exhaustion. On many occasions, ammolite is used to help connect the user to their past lives during meditation.
Daily gem: Today's gem is MALACHITE! Malachite is a brilliantly green banded gemstone. It is a rather soft gem with a hardness of 3.5-4. This makes it a very soft gemstone. Its so soft that a copper penny would be able to scratch it!
Formation: Malachite is a secondary mineral of copper that is always green and opaque, forming when copper minerals are altered by other chemicals, such as carbonated water or interacting with limestone. Banded forms of malachite typically are stalactitic, being comprised of dense inter-growths of tiny, fibrous needles.
Metaphysical Properties: Malachite is a gem known as the "stone of transformation," and should be used in small doses to clean the wearer's energy, drawing out a balance in the wearer and healing them positively. It is also known to balance the wears moods and heal cramps, as well as lower blood pressure, and treat many joint related illnesses.

Daily gem: ROSE QUARTZ! Rose quartz is a variety of quartz known for its pale rosy pink coloration. As a quartz, it has a Mohs Hardness of 7! This is a slightly above average hardness, and a steel nail (6.5) cannot scratch it.
Formation: As a quartz, Rose quartz is a hard crystalline mineral made up of silicon and oxygen atoms. Quartz forms when magma pushes through weak points in the Earth’s crust, picking up minerals as it goes. As it cools, the silicon it picked up bonds with oxygen, forming a quartz crystal. If titanium is present during the cooling process, ROSE QUARTZ is formed!
Metaphysical Properties: Rose quartz is known as the stone of universal love! It restores trust and harmony while purifying and promoting healing, peace, love, friendship, self worth, & calmness. It helps the wearer open their heart, and comforts them in times of grief. It overall dispels negativity, protecting against environmental pollution.

Amethyst is a protective stone. Metaphysically it is a natural tranquilizer, relieving stress, strain, irritability, balancing mood swings while it dispels anger, rage, fear and anxiety. It helps you cleanse yourself, encouraging selflessness in the wearer
Amethyst often forms as geodes (hollow rocks with crystals lining the inner walls). To make a geodes, gas cavities form in lava when the lava hardens. Then the cavities fill with a silica-rich liquid that have trace amounts of iron. When that liquid hardens, it forms AMETHYST!
Daily Gem: AMETHYST! Amethyst is a violet form of quartz. It comes in many shades of beautiful purple! As a quartz, it has a Mohs Hardness of 7!
Daily Gem: LABRADORITE! Labradorite is a feldspar mineral that is known for it refracting light to make iridescent flashes of blue, gold, green, or red. It is softer than quartz with a Mohs Hardness of 6-6.5!
