Peridot Gemstones, Color Stability Issue.
If you observe the crisp green color of peridot gems, it does seem that the stone is either treated in color or just coated with a green color on the surface. Fortunately, both the above assumptions regarding the color of peridot gems are not true. Peridot gems have a gorgeous bright green color which at times can show shades of yellow. The wonderful thing about the green color of peridot is that it is natural. As of now, no treatment process has been used to enhance or alter the color of peridot in any way. Unlike green emerald which is always treated with natural oils and green jade most of which is dyed, peridot stones have a natural color. The color stability factor also works in favor of peridot. The color of a peridot stone will not fade over time. Domestic toilet soap or cooking oils will not affect the beauty of your peridot gemstone. Exposure to sunlight will also not cause the gemstone to fade.
If you consider the facts that peridot can have good clarity and color uniformity, it is one of the most attractively priced green gemstones. The gemstone can therefore be found in gold and silver jewelry, and green has always remained in the minds of fashion concious gem and jewelry buyers.

Report On Square Shaped Gems

Square Shaped Gems. The Directstones Report.

At first glance it might seem that square shaped gems are no different from gems of other shapes. However there are some important issues that need to be understood and implemented when using gems with square shape in jewelry. The importance of understanding square shaped gems begins right at the cutting and storing stage. Remember that the corners of square gems are generally quite pointed and sharp. The edges of most cut gems also happen to be the thinnest portion of the gemstone. These issues need to be considered when the cutter cuts a square gem. It is a good idea to give some thickness to the edges and corners of cut stones. This might mean custom cutting the gem but, for the final buyer it is a great benefit in the longterm.

When it comes to setting a square shaped gem, the craftsman needs to ensure that bending the prongs over the corners of the gem does not damage the sharp corners in any way. The designer of the jewel that uses square gems also has an important role to play. It is important to provide ‘V’ right angle type of prongs for square gemstone jewelry. These type of prongs offer good protection for the sharp corners. Exposing the naked corners of a square shaped gem leave the gem prone to damage by even moderate physical impact.

When you buy and wear a jewel with a square stone, you will need to ensure that the design structure and craftsmanship have played their role well. Even with this happening, you will need to store the ring and wear it with some amount of caution. When storing loose square gems, always keep them separated from each other and from other gems. Minimum handling is a good way to ensure that a square shaped gemstone keeps in good shape for a long time.

Iolite Gems, Color Range For Iolite Gem Stones.

Iolite gems are suitable for all kinds of jewelry. The different color shades of blue-violet for this gem ensures that there is a color to please everyone. The above image provided by Directstones clearly shows the three main color shades that iolite stones can be found in. The medium color iolite gem is shown first because, it is also the most popular and desired color for iolite gemstones. In many cases, the color of medium color iolite stones can come very close to the much more expensive tanzanite gem stone. This is the color that is suitable for yellow or white gold iolite gem stone jewelry. The color is visible even in normal light conditions. It is not just good iolite that is required to cut such a gem, expert knowledge of orienting the gem the right way during the cutting process is also vital. All the three iolite stones shown above are cut by some of Thailand’s finest stone cutters.

Moving to the next color shade of iolite is the very deep and saturated color. This gem is not very common, in most cases you will find men requesting for deep color iolite gems in their rings. With this gemstone, color is visible when light of good intensity strikes the gem stone. There is something very mystical about deep colored iolite stones, it seems like you were looking into a deep pit and saw the color at the bottom of the pit. While saying that medium color iolite gemstones are more popularly, it is equally true that an iolite gemstone jewelry buyer who expects deep saturated color will never be satisfied with the more vivid medium color shades.

The bottom stone on the image is a pale to light color iolite stone. Lower in popularity to the dark and medium iolite stones, this stone does has some loyal followers. If you want to combine pink gems with any other stones, this shade of iolite offers an interesting option. However with this light shade of iolite gemstones, a high degree of clarity is desirable. Inclusions or cracks will be clearly visible in gems iolite gems that have a pale color.

We have a more complete report on the iolite gemstone for your reference. You will also know how and why Tanzanite, a gemstone that has lower durability than iolite went on to steal the limelight from iolite. Check out this and more at http://www.iolite.directstones.com/iolite-gemstones-01.htm

Green Gemstones, Options For Green Gems.

Green Gemstone Options, About Green Color Gems

The color green has been very popular for decades, this not only for green gemstones. The word green is today related to environment conciousness and conservation too. It is therefore no surprise that many gem and jewelry lovers choose green stones for their jewels. In the next few paragraphs we will explain a few issues related to how you should choose a green stone.

When it comes to green stones, there are some common gems that are known to most gem buyers. Peridot and emerald are the most common green stones. Infact early in history, most green stones were considered to be emeralds. It was not just the ordinary man who got confused regarding the true identity of some green stones. Cleopatra was an avid lover of emerald stones, her collection included some of the most expensive jewels. And yet when the knowledge of gemology spread, it was found that many ‘emerald’ gems owned by her included peridot and not emerald!

Many people wear a birth stone ring, in this case there is not much you can do about green stone options. Emerald that we just spoke of is a variety of (green) beryl. It is also the birth stone for the month of May. An interesting thing about emeralds is that, they will also include inclusions and fissures. This natural occurence reduces the clarity of this green gem, it also reduces the durability of the gem by a certain degree. The other green stone peridot, can be a rich green or contain color tones of yellow. Peridot is the August birth stone and has better clarity and lustre as compared to emerald. It is also much cheaper than emerald but, cannot be called a cheap gem since prices are in the medium price range.

One very interesting green stone is bloodstone, it is a dark green jasper with a scarce springling of red spots. If you wondered why a gem stone that is dark green should be called a bloodstone, there is a very interesting answer to your query. The Christians believe that a piece of green jasper that lay at the foot of Lord Christ during crucifixtion, got stained with the blood  of the Lord. It was this belief that gave the stone it’s name. Though not a primary birthstone in modern birth stone charts, many charts list it as a March birthstone.

Jade is one more green stone and can include both jadeite and nephrite. A significant portion of the jade that you come across will have a green color. Most of the green jade is today dyed to enhance color. The color treatment is permanent and gives the stone a uniform green color. There is always a big debate regarding whether you should choose a natural green jade or a piece that has been dyed. The conclusion for this debate is quite simple and mainly involves the price factor. If you had to get a 4 carat green jade that was dyed, you might pay in the range of 20 U.S$ to 35 U.S$. Compare this to a jade piece that has not been dyed but, has the same color quality as the dyed piece. You could pay around 1,000 U.S$ to 1,500 U.S$ for the natural color stone. But if you wanted a green jade and did not worry about the color saturation or spread, then check an undyed green jade gemstone. You can find one in the 100 U.S$ to 200 U.S$ price range.

When it comes to green stones, it is often believed that these gems are not suitable for mens jewels. There is no technical reason for this, so some notes and suggestions are in order. If you need a mens ring with a green gem and do not want a bright green stone, bloodstone and green tourmaline might be a good choice. Green tourmalines have one advantage, it is a sturdy stone and will withstand daily wear and tear. The color is a very dark green and surely not bright.

The above suggestions are surely not the only green gems that you will come across. Your jeweler can provide more information but equip yourself with the information given in this article. You can then make the right queries and ask the right questions to allow you make the right decision. Australian Chrysoprase, demantoid garnet, tsavorite garnet, aventurine and green apatite are a few more names of gems with a green color.

Large Sapphires Becoming Rarer

Large Sapphires Becoming Rarer

Big Pink Sapphire Gemstone.

If you had to compare a large blue sapphire and a large pink sapphire gem stone, it would be much harder to find a large pink sapphire gem. Most gem experts agree that A good pink sapphire in the 2.2 to 2.5 carat size would be called a large pink sapphire. It is therefore no surprise that the 3.5 carat pink sapphire from Directstones attracted huge interest the moment it was published on the website.

With dimensions of 10mm x 7.5mm supported with a 3.5 carat weight, this big pink sapphire is not for the faint hearted. The gem has a gorgeous almost hypnotic pink color and good clarity. The rough piece before being cut by Directstones gem cutters weighed around 16 to 17 carats. Ensuring that the right proportions of size and weight were maintained meant that, over 80% of the rough pink sapphire was lost in the cutting process.

Going by the quality, size and color this is a rare pink sapphire gem but Directstones made an alarming claim. The gem expert team claimed that there are more from where this awesome piece came from. The company promises to fulfill all requirements for custom cut pink sapphires and that includes matching sets. While the price tag of 3,500 U.S$ is not cheap it surely is not as extravagant as the magnetic charm of this scintillating gem stone. The designing team at Kaisilver suggested that this tremendous gem be reserved for a unique sapphire wedding or engagement ring.
