Peridot is a well-known and ancient gemstone, with jewelry pieces dating all the way back to the Pharaohs in Egypt. The gem variety of the mineral Olivine, it makes a lovely light green to olive-green gemstone. The intensity of color depends on the amount of iron present in a Peridot’s chemical structure; the more iron it contains the deeper green it will be. The most desirable color of Peridot is deep olive-green with a slight yellowish tint. Deeper olive-green tones tend to be more valuable than lighter colored greens and yellowish-greens.

Ruby is the birthstone for July, and the 15th and 40th year anniversary gemstone.
Undoubtedly one of the rarest gemstones. This aluminum oxide gemstone can certainly protect itself, as it is the second hardest gemstone behind the diamond. The ruby’s extreme durability allow it to be cut into every size and shape, creating unique examples of fine jewelry.
Corundum is the host mineral in which ruby deposits are found; the trace elements introduced into the corundum determine whether or not a ruby is formed. When the coloring agent chromium is introduced, a ruby is produced, while other trace elements will produce the gemstones known as sapphires (iron, for example, is the element responsible for blue sapphire).
Historically the leading ruby-mining countries have been Myanmar (Burma) and Sri Lanka. Today, rubies are found in Thailand, Madagascar, Africa, and Vietnam. Due to the U.S. moratorium on gemstones and pearls from Myanmar, fine rubies are particularly difficult to obtain. Natural rubies are a very slow-growing crystal, making it rare to see a large ruby of almost any quality.

Besides Pearl being June’s traditional birthstone, “Alexandrite” is a lovely alternative.
Those born in June are lucky to claim their birthstone as the beautiful precious gem alexandrite. This exciting gem may appear to be magic when it appears in shades of green and blue or yellow and structure; absorbing light wavelengths within the yellow spectrum, making the gem appear to change color in different light sources.
Alexandrite rose to prominence in 1830 in the Ural Mountains of Russia. Tied to the czar, Alexander II, the gem gets his name from him. The colors of the stone, which change from green to red due to light source, were the Russian flag’s colors at the time. The Ural Mountains were quickly depleted of the gem due to over mining. Russian royals were gifted with alexandrite jewelry in the forms of necklaces and rings.
Alexandrite can be found in Brazil, Sri Lanka, and East Africa.
These changes in color occur in chrysoberyl (alexandrite’s family), wherein aluminum is replaced by chromium ions in alexandrite’s structure; absorbings light wavelengths within the yellow spectrum, making the gem appear to change color in different light sources.
Notable June birthdays include actors Johnny Depp and Chris Evans, musicians Lana Del Rey and Ariana Grande, sports legends Lou Gehrig and Joe Montana, and Hollywood stars including Marilyn Monroe and Tony Curtis, and cutest wargamer Colin Brady 🙂 .

Natural Pearls are very delicate gems and can be easily damaged by the surrounding conditions. It is extremely important to care for pearl jewelry. With proper care the gems will last for centuries.
1) When pearls are worn very often and close to the skin they get eroded or damaged with contact with even the mildest of acids given out by the skin. Hence the use of pearl jewelry very often in humid places is not advisable.
2) Pearl jewelry like pearl earrings, pearl rings etc should not be kept in cotton wool as it contains small amounts of acids that may damage the pearl in the long run.
3) String of pearls or pearl jewelry should not be kept in polythene bags as there isn’t enough moisture for the pearls in these bags, which will create a water loss and damage the outer surface of the pearls.
4) The best way of storing pearls would be to keep them well wrapped in white linen cloth or pure silk.
5) Cosmetics and perfumes must never come in contact with pearls as the acids and chemicals most certainly will damage them.
6) Restringing of pearls that are very often used is a very good idea as many a times the string may absorb the perfume of cosmetics used and in turn damage the pearl. The string used (if silk) by itself may wear out or may break. It is advisable to restring regularly used pearls once every six months.
7) The best way of stringing pears is to have a knot at the end of each pearl so that in case of breakage of the string only one pearl is lost.
Pearls are categorized as organic gem material and are amongst the oldest of precious gems. In history pearls have been very valuable, second only to the diamond. The first record of the use of pearls in history is the fishing of the famous orient Basra pearl around the year 300 B.C.
The gemstone Emerald is the green variety of the mineral beryl. Emerald is the May birthstone.
The wonderful green color of emerald is unparalleled in the gem kingdom. Emerald’s precious green color is caused by small amounts of chromium and enhanced by traces of iron. Unlike other beryls, emeralds usually contain inclusions and other flaws. These flaws are not looked on as negative aspects for emerald like they would be for other gemstones. Indeed, these flaws are considered part of the character of the stone and are used to assure the purchaser of a natural stone.
Even artificial emeralds often contain flaws, however, as the process of growing artificial emeralds mimics the way nature does it (slow crystal growth from a molten mix).
Nearly all emeralds, even many “natural” stones, have been treated to improve clarity, generally by immersing them in oil. For gemstones, a green colored oil is sometimes used, “improving” the color as well. Unfortunately, this oil may evaporate over the years, making flaws appear where none were visible at the time of purchase. A high-grade mineral oil may be used to improve the appearance again.
