  4. 4. Your Birthstone Complements your Light and SpiritMost people wear their birthstone as a piece of jewelry and think of it as a ‘fashionstatement’. Wearing one’s birthstone or gemstone of the month of one’s birth, wastradition during biblical days as described in Exodus 28: 15-20 in the Old testament. Itrefers to the breastplate of Aaron, a piece of ceremonial garb that was set with 12gemstones that represented the 12 Apostles or 12 Tribes of Israel and corresponded to the12 signs of the Zodiac. Some believe that wearing one’s birthstone in a piece of jewelrycalls forth very real energy and magical properties that correspond to the month of yourbirth.For the purposes of this short informational guide, I’m going to briefly mention what eachstone’s accepted metaphysical powers are said to be.The purpose of this guide is to arm you with enough information so that you can make aninformed decision when you decide to buy a piece of gemstone jewelry for yourself or forsomeone else. Because it’s a gemstone doesn’t mean that it has to be your or therecipient’s birthstone. Much of the time gemstones are bought simply for their beauty, butmore often because of the properties they are believed to possess and the benefits one isbelieved to receive.Before I start talking about individual stones, I’d like to give you some basic informationthat you can apply when you go shopping for the perfect gemstone or birthstone.

  5. 5. Things You should know about your GemstonePeople often differentiate between stones by calling them either ‘precious’ or ‘semi-precious’. The diamond, ruby, sapphire and emerald are considered to be ‘precious’ stoneswhile the others are ‘semi-precious stones’. This is not a science based method, but rathera method that was used in ancient times and continued by the Western world and someother civilizations. However, it is reflective of the quality and rarity of the stones at thattime. This method is not necessarily reflective of today’s values.The terms ‘precious’ and ‘semi-precious’ are misleading and imply that certain stones arenaturally more valuable than others, no matter what the circumstances, and this isn’t true.Certain stones, such as the diamond, the emerald, the ruby and the sapphire havereputations that exceed those of the other gemstones and will always be more desirableand seen as more valuable.

  6. 6. Things You should know about your GemstoneStones are classified by hardness (measured on the Mohs scale, diamonds being thehardest at 10) and translucency.Gemologist today identify gemstones using technical and scientific terms. First they usethe stones chemical composition, as this determines the color and type of the stone. Manystones are crystals, so they’re classified by their crystal system; cubic, trigonal or monoclini.The form, or shape, the gem is usually found in, is termed habit, e.g., the diamond isusually found as an octahedron.If this information has piqued your interest and you want more information, I suggest youlook into the study of gemstones, or look up gemstones to learn more.

  7. 7. Month | January Birthstone | GarnetThe beautiful garnet is the birthstone for January. The color for January is the red or crimson coloredgarnet. The stone can be found in all colors, with blue being the rarest and hardest to find. So rarethat only recently did it become known that there was a blue garnet. The blue color is visible whenthe stone changes colors, from blue-green in daylight, to purple in incandescent light. The garnet ismy birthstone & I just recently leaned to appreciate it. I had never seen the stone set in silver andfor me, the color change in the setting just made it pop out at me. And for that reason, the jewelrythat is pictured to show the stones, throughout this guide, will be both yellow and white gold orsilver. The setting color definitely makes a difference.Gemstone quality red, green, yellow and orange garnets are translucent while the opaque are morefor industrial use as abrasives, e.g. garnet sanding paper. On the Mohs scale, garnet can measureanywhere between 6.5 -7.5. Garnets are mostly known as the dark, blood-red stone, and as thestone for a successful business. It is said to protect one on trips and is the stone of purity and truthas well as a symbol of love and compassion.
  8. 8. Month | February Birthstone | AmethystAmethyst is a member of the quartz family. In ancient times, amethysts were prized by royalty fortheir regal, purple color. The noble and well-to-do of early days, used amethyst for most of theirengraved, or carved gems. The color of amethyst ranges from pale lilac to a deep purple andmeasures 7 on the Mohs scales it is quite suited to jewelry. The color in amethyst is due toirradiation which caused the iron ions to rearrange themselves in the crystal lattice affecting thecolor in a reversible process. Upon exposure to heat, the effects from irradiation can be cancelledand amethyst becomes yellow or sometimes green. The Greeks believed the amethyst couldprevent intoxication and therefore drank from goblets carved from amethyst. Greek mythology saysthe stones gets it color and name from Amethystos, a chaste maiden who was being pursued byDionysus, the god of wine, and intoxication. The story says the maiden refused his advances andprayed to the gods to remain chaste. The goddess Artemis answered her prayer and transformedher into a white stone. Dionysus was humbled by Amethystos’ desire to remain chaste and pouredwine over the statue as an offering and dyed the crystals purple. I liked this version of the storybest.The amethyst is believed to bring it’s wearer good luck and radiate love. The amethyst also promotesan overall sense of soothing, well being and peace.
