Pearl is the Birthstone for June Birthdays

The word Pearl comes from the Latin word "pirum" (it means "pear" or the shape).  Pearls have are found inside the shell of an oyster, clam or mussel.




How are Pearls Made?
Cultured pearls are produced when man has introduced an irritant into the oyster or mussel and these are then harvested from their saltwater or freshwater environments. 



  • Pearls are formed because of a secretion of shelly substance around some irritating foreign particle
  • Natural Pearls are either saltwater found in gulfs, bays, seas and oceans or freshwater found in rivers and lakes
  • Kokichi Mikimoto was the Japanese man credited as the creator of the cultured pearl
  • Natural Pearls are found in the waters of these countries: Persian Gulf, the Gulf of Mannar, the South Pacific, the Gulf of California, the Gulf of Mexico, the Pacific coast of Mexico, Europe, Japan and Australia
  • Pearls come in a wide range of natural colors and shades. The type of oyster or mussel determines the color along with the geographical area

Colors: Natural (not dyed) colors are white, pink pearls, lilac, cream, grey, black and gold



  • Pink pearls are extremely popular
  • The Silver-lipped oyster is found in the South Sea around Australia which produces large white and silvery white South Sea pearls
  • Tahitian pearls range from black, light black/silvery and dark grey. The rare peacock green color is also referred to as a black pearl. The cheaper black pearls, especially freshwater, are usually dyed

  • Iridescence is the pearly lustre caused by the effect of colors which may be like those of the rainbow or a combination of colors such as pink, blue, green, and silver

  • Gold or golden pearls are the colors found in the South Sea

Types of Pearls:
  • South Sea pearls are famous for their gold colors

  • The Akoya Pearl is famous for their blue colors - from the Akoya oyster and are cultured seawater pearls produced in China and Japan. The Japanese Akoya pearl (cultured) have brilliant lustre and a higher quality than Chinese Akoya pearl
  • Persian Gulf Pearls, Oriental, are some of the finest natural pearls
  • Tahitian pearls are famous for their natural black colors
  • Mabe pearls are grown in Japan, Indonesia and Australia. Mabe pearls are cultured pearls grown against the inside shell of an oyster rather than within the oyster’s body producing a flat back pearl which are often used in earrings
  • The Mikimoto pearl are a leading brand. The company was founded by Kokichi Mikimoto who was the Japanese man credited as the creator of cultured pearls
  • Lake Biwa Pearls are freshwater pearls grown in Japan

October Birthstone – Opal – Libra

 
The Opal was called "Cupid Paederos" by the Romans, meaning a child beautiful as love.  A legend gives the gemstone's origin as “it fell from heaven in a flash of fiery lightning.” 
Ancient monarchs treasured Opals, both for their beauty and for their presumed protective powers.  They were set into crowns and worn in necklaces to ward off evil and to protect the eyesight.  These gemstones were also ground and ingested for their healing properties and to ward off nightmares.

The Opal dates back to prehistoric times.  It is a non-crystallized silica, which is a mineral found near the earth's surface in areas where ancient geothermal hot springs once existed.  As the hot springs dried up, layers of the silica, combined with water, were deposited into the cracks and cavities of the bedrock, forming Opal.  This gemstone actually contains up to 30% water, so it must be protected from heat or harsh chemicals, both of which will cause drying and may lead to cracking and loss of iridescence.  Opal must also be guarded from blows, since it is relatively soft and breaks easily.  
Most of the world's Opal deposits are found in Southern Australia.  Other sources are Brazil, Mexico, Czechoslovakia and Nevada.  Quality Opal is very expensive, because it requires special care when cutting, polishing and setting into jewelry.
Alternate Birthstones: Peridot, Agate, Aquamarine,  Tourmaline and Sapphire
An alternate birthstone for October, Pink Tourmaline has the seemingly magical property of pyroelectricity.  Scientifically speaking, this means that when heated, the gem takes on a static electric charge, making it capable of attracting lightweight objects.

Opal Care Very heat sensitive, clean with warm or room temperature soap and water. Avoid wearing gem where it will get rough treatment.
  • Opals are delicate, but well worth the care. Their most significant weakness has to do with the water content. If an opal is allowed to dry, it will crack and craze. In most cases, they do not need any special care while stored. However, if you live in a very dry climate, or keep them in a dehumidified room, some precautions are necessary. Keeping them in a tight plastic bag, with a damp piece of cotton or fabric will prevent dehydration.
  • Storing an opal in oil or glycerin is not recommended. It is unlikely to damage the opal, but it is unnecessary and requires tedious cleaning.
  • Because of their water content, opals are also highly sensitive to sudden changes in temperature. I know of a woman in Pennsylvania who wore a brooch on the outside of her coat. As she passed from the warmth of her house to the winter cold, there was an audible "crack" as her opal self-destructed.
  • Opals do not mind being hot or cold, it is the rate of change that damages them. You need to avoid situation like the one above, going from a warm house to the winter's cold. Simply wearing an opal under clothing will protect them. Also, do not store opals near a heat source, an open window, etc., where they can be exposed to sudden temperature changes.
  • Being somewhat soft, they scratch easily. Realize that a large component of dust is quartz at 7 in hardness. At 5.5 to 6 in hardness, simply wiping the dust off an opal will gradually reduce its polish. The solution is to clean your opals using a soft cloth or brush, a mild detergent, and room temperature water. Then rinse the jewels to remove any residue.
caution that must be exercised in cutting, polishing and setting it into jewelry.  
A gift of Opal is symbolic of faithfulness and confidence.  And the powerful energy radiating from this fiery gemstone will surely illuminate any occasion!
Opals correspond to the astrological sign of Libra - The sign of the Scales - September 23 - October 23

Sapphire is September's Birthstone


The Greek word "sapphirus", meaning blue, is the origin of the word sapphire. Sapphires are considered royal gemstones-priests and kings considered them symbolic of wisdom and purity.
Social, religious, biblical and Christian symbolism all have included the color blue representing heavenly grace. Since ancient times, blue has been considered a lucky color among the peoples of the Middle East and North Africa. According to several rabbinic sages, blue is the color of God’s Glory. Staring at this color aids in mediation, bringing us a glimpse of the “pavement of sapphire, like the very sky for purity,” which is a likeness of the Throne of God. (The Hebrew word for glory, kavod, means “blue” in Arabic.)

Here are some finds from the Etsy Promofrenzy Team

Sapphire is a variety of the mineral corundum.  Corundum is found in every color of the rainbow, with red being designated as ruby and all other hues Sapphire. The most prized color of Sapphire is a rich, deep blue. Sapphires with colors other than blue are generally referred to as fancy sapphires. The distinctive blue of the sapphire is due to minute amounts of oxide of iron and titanium in the stone.

These gemstones were mined as early as the 7th Century BCE from India and what is now Sri Lanka. They are found today in Sri Lanka, Kashmir, Myanmar, Thailand, Australia, Nigeria, Kenya, Tanzania, China, Madagascar, and the United States. 

Large specimens of Corundum crystals are rare, although the 563-carat Star of India can be seen in the American Museum of Natural History in New York, NY.  This is the largest and most famous of star Sapphires, which are cut to reflect light from inclusions within the stone, revealing a bright six-legged star pattern. 

The Sapphire is second only to the Diamond in hardness, making it a durable gemstone for setting into jewelry.  A gift of Sapphire represents sincerity and faithfulness. As nourishing to the soul as gazing up at the sky on a summer day, this brilliant blue gemstone is truly a heavenly choice!

August Birthstone - Peridot

Last month we featured July and its stone ruby.  The next month is August, and we will feature its stone!

Peridot is the August birthstone. This green gemstone is believed to help with nightmares, bring prosperity, fertility and healing. Peridot was once called the "gem of the sun" in ancient times.


Peridot stone



Peridot is actually a variety of the mineral olivine.  Good quality peridot looks like a delicious green apple. The best peridot comes from Italy and has a rich olive color. Peridot from America is a light yellow green color.

Peridot is a unique gem in that it is formed in volcanic fire. The best source of peridot is in America on the San Carlos Native American Reservation. Peridot was once known as chrysolite in ancient times. Peridot comes in only one color, green. This is unusual as most gemstones come in at least a few colors. Top quality peridot should have no inclusions even under magnification.
