Gold Rings - Important Facts

GOLD RING

One thing you can say about gold rings is that they are timeless pieces that are always in style. They are not only beautiful, but also wear-friendly since, unlike sterling silver, they don't tarnish. Another great attribute is that people with allergies to certain metals, or find they have a problem with staining from metals that have been combined with gold, don't have a problem with gold itself.

Gold is a versatile metal, able to be worked in virtually any shape, whether it be small, but sturdy, strands to thin sheets. In fact, just one ounce has the ability to be hammered into an extremely thin sheet measuring at ten feet square. Artisans, especially makers of gold rings, can manipulate gold into any desired shape.

When choosing gold rings you need to look at the gold's karat factor. Different karat numbers are what describe just how much pure gold is in the rings. The percentage of gold in the rings is higher when the karat number is higher.

For example, 24K rings are pure gold, 18K is 75% gold with 18 parts of gold and 6 parts of another metal, 14K, the most common, is 58.3% gold with 14 parts of gold and 10 parts of another metal, 12K is 50% gold with 12 parts of gold and 12 parts of another metal, and, lastly, 10K, the minimum karat that can be described as gold, is a mere 41.7% gold with 10 parts gold and 14 parts of another metal.

Gold Ring

Gold rings made in Europe will have different markings. For example, 18K will be marked as 750, 14K will be marked as 585, and 12 K will be marked as 417. These marking stand for the percentage of gold the rings contain.

Most gold rings aren't made of pure gold since it can be quite soft and not very practical for daily wear. In mot cases, other metals will have been mixed with the gold in order to heighten the durability, as well as lower the price.

When metallurgists add other metals to gold it allows them to change the gold's color. To create white gold Palladium, also known as nickel, is added. The addition of copper products creates a rose/pink color, while adding silver can give gold a greenish tint.

When choosing the type of gold rings that is right for you, you must decide how often you will wear them and what type of karat number will fit this need. If you are allergic to such metals as nickel, you should choose gold rings that have a higher gold content. This means that gold rings marked with 18K or 22K are best for you.

GOLD RING

If you plan to wear your rings only on occasion, and don't necessarily have to have the best gold there is, then you have the option of choosing gold rings that are gold filled or even gold plated. This would not be a good choice if you do plan to wear the gold rings on a daily basis since a lot of use will reduce the gold layer, therefore exposing the metal that is underneath and possibly causing staining or even an allergic reaction.

If you plan to purchase gold rings that you want to last a very long time, then make sure you buy a high quality item.

Aquamarine

Aquamarine Gemstone Oval

From the light blue of the sky to the deep blue of the sea, aquamarines shine over an extraordinarily beautiful range of mainly light blue colours. Aquamarine is a fascinatingly beautiful gemstone. Women the world over love it for its fine blue shades which can complement almost any skin or eye colour, and creative gemstone designers are inspired by it as they are by hardly any other gem, which enables them to create new artistic cuts again and again.

Its light blue arouses feelings of sympathy, trust, harmony and friendship. Good feelings. Feelings which are based on mutuality and which prove their worth in lasting relationships. The blue of aquamarine is a divine, eternal colour, because it is the colour of the sky. However, aquamarine blue is also the colour of water with its life-giving force. And aquamarine really does seem to have captured the lucid blue of the oceans. No wonder, when you consider that according to the saga it originated in the treasure chest of fabulous mermaids, and has, since ancient times, been regarded as the sailors' lucky stone. Its name is derived from the Latin 'aqua' (water) and 'mare' (sea). It is said that its strengths are developed to their best advantage when it is placed in water which is bathed in sunlight. However, it is surely better still to wear aquamarine, since according to the old traditions this promises a happy marriage and is said to bring the woman who wears it joy and wealth into the bargain. An ideal gem, not only for loving and married couples.

A gemstone with many good qualities

Aquamarine Gemstone Sterling Silver Ring

Aquamarine is one of our most popular and best-known gemstones, and distinguishes itself by many good qualities. It is almost as popular as the classics: ruby, sapphire and emerald. In fact it is related to the emerald, both belonging to the beryl family. The colour of aquamarine, however, is usually more even than that of the emerald. Much more often than its famous green cousin, aquamarine is almost entirely free of inclusions. Aquamarine has good hardness (7.5 to 8 on the Mohs scale) and a wonderful shine. That hardness makes it very tough and protects it to a large extent from scratches. Iron is the substance which gives aquamarine its colour, a colour which ranges from an almost indiscernible pale blue to a strong sea-blue. The more intense the colour of an aquamarine, the more value is put on it. Some aquamarines have a light, greenish shimmer; that too is a typical feature. However, it is a pure, clear blue that continues to epitomise the aquamarine, because it brings out so well the immaculate transparency and magnificent shine of this gemstone.

Favorite stone of modern designers

There is hardly any other gemstone in modern jewellery design which is refined in such a variety of ways as aquamarine. Whether it is fashioned as a clear, transparent gem in the classical step cut, or creatively cut in a more modern design, it is always fascinatingly beautiful. Uncut too, or with many inclusions which can be brought into play by the designer in the way in which the stone is cut, it can be refined to produce the most beautiful creations. Designers call it their favourite gemstone. Again and again they take the world by surprise with a new, modern artistic cut, and when they are breaking new ground, aquamarine is a gem that they particularly like to work with. Without doubt, these creative designer cuts have contributed to the great popularity of this gem. The lucid colour of aquamarine makes it easy to see inclusions. For this reason, aquamarine should always be of the greatest possible transparency. On the other hand, particularly charming effects can sometimes be achieved in the way the gemstone is cut by bringing the inclusions into play. The light colour of aquamarine leaves the gemstone designer free to bring out the brilliance of the gem with fine grooves, notches, curves and edges. In this way, each aquamarine becomes a unique specimen, whose magical attraction no woman can resist.

Common Shapes For Cutting A Gemstone.

Common Shapes for Cutting a Gemstone

Gemstones are rarely attractive when they come as raw materials, but once they receive proper treatment and cutting they can become objects of exquisite beauty. The shape of a stone refers to its physical shape, while the cut refers to the quality of the cut. The shape is about the face-up outline displayed by the cut of a gemstone. The natural crystal structure and the conditions in which the crystal developed influence the shape of a natural gemstone. Gem cutters form flat and symmetrical planes, named facets which can capture and reflect light to emphasize colours and sparkle of the finished stones.

For rings, gemstones usually come in brilliant round shapes, princess shapes or emerald shapes. The brilliant round shape is the most common shape for diamond rings. This shape allows the stone to achieve maximum light reflection and the sparkling effect can be outstanding.

The simple square shape is called the princess shape and it is suitable for inclusion as single stones or small groups of stones. The rectangular shape is called the emerald shape which can highlight the elegance of larger coloured gemstones among which sapphires or emeralds are the greatest. A diamond with a brilliant or round cut has 58 facets, of which 33 are above the girdle and 25 are below.

For other pieces of jewellery the pear shape, heart shape or marquise are the most common ways of cutting a gemstone. The pear shape resembles a tear drop and larger gemstones such as sapphires and diamonds can make wonderful pear shaped jewellery. Red rubies or pink diamonds are perfect for heart shaped jewellery.

The cut of a gemstone refers to its proportions, namely height and width. If a gemstone is well cut, it will reflect more light and be more sparkling.
