Birthstones and their vivid colors have long been a way to connect your birth month with rare and unique gemstones. They are a meaningful gift for mom, a friend, spouse, or family member during a special occasion. But they mean much more than that as you'll find out below.
A Gemstone popularly associated with the month or astrological sign of one's birth.
Garnet, the birthstone of January, is mined in a rainbow of colors. From the fiery orange of Mandarin Garnet to the rich green of Tsavorite Garnet and to the most widely recognized color of Pyrope Garnet, it is considered a great gift to symbolize friendship and trust.
Geological information:Garnets are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives.
All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition. The different species are pyrope, almandine, spessartine, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite. The garnets make up two solid solution series: pyrope-almandine-spessartine and uvarovite-grossular-andradite.

Amethyst, the birthstone of February, is a variety of Quartz that carries a spectacular purple color that ranges from a blend of deep violet and red to a lighter lilac hue. Ancient Greeks believed that the stone protected the wearer from drunkenness and enabled them to keep a balanced mindset.
Geological information:Amethyst is a violet variety of quartz often used in jewelry. The range of colour includes reddish-violet tints of pale or almost colourless shades, and deep, rich tones of pure violet.
Aquamarine, the birthstone of March, has a rich color and has long been a symbol of youth, health and hope. Its mesmerizing color ranges from pale to deep blue and are reminiscent of the sea. A perfect birthstone for March, the Aquamarine creates a beautiful accent to spring and summer wardrobes.
Geological information:Aquamarine (from Latin: aqua marina, "water of the sea") is a blue or cyan variety of beryl. It occurs at most localities which yield ordinary beryl. The gem-gravel placer deposits of Sri Lanka contain aquamarine. Clear yellow beryl, such as that occurring in Brazil, is sometimes called aquamarine chrysolite. The deep blue version of aquamarine is called maxixe. Maxixe is commonly found in the country of Madagascar. Its color fades to white when exposed to sunlight or is subjected to heat treatment, though the color returns with irradiation.
Diamonds, the birthstone of April, are commonly associated with love which make it the perfect gift for a loved one. While white diamonds are most common, fancy colored diamonds can be found in various colors including yellow, blue, pink and a variety of others as well.
Geological information:Diamond is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.
Emerald, the birthstone of May, carries the rich green color of Spring and radiates a beautiful vivid tone. They are considered to be a symbol of rebirth and love. Emeralds are the rarest gemstones and are typically mined in Colombia, Brazil, Afghanistan and Zambia.
Geological information:Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor. It is a cycosilicate.
June birthdays claim two birthstones; pearl and Alexandrite. Pearls have been wildly popular in jewelry for centuries because of their natural beauty. Alexandrite gemstones are extremely rare and desirable since they change color based on the lighting.
Geological information:The alexandrite variety of Chrysoberyl displays a color change (alexandrite effect) dependent upon the nature of ambient lighting. Alexandrite effect is the phenomenon of an observed color change from greenish to reddish with a change in source illumination. Alexandrite results from small scale replacement of aluminium by chromium ions in the crystal structure, which causes intense absorption of light over a narrow range of wavelengths in the yellow region (580 nm) of the visible light spectrum. Because human vision is more sensitive to light in the green spectrum and the red spectrum, alexandrite appears greenish in daylight where a full spectrum of visible light is present and reddish in incandescent light which emits less green and blue spectrum.
