Ever wondered how to find the world’s greatest emeralds?

Recently, Emerald jewelry had a gigantic boom in popularity in both local and international markets. This brings up another topic for wholesalers and buyers on where to buy the best, highest-quality emerald jewelry. I have your answer right here.

Emeralds from Egyptian mines have long been considered to be the best due to the fact that Egypt contains the first known emerald mines. Although, the known start date is not certain as there is a huge time gape, 300-2000 BC. Making the situation even more complicated, many different terms were used for emerald. Any green stone with a light glow was referred to as an emerald.  The heaviest known emerald-mining was done between 330-1237 BC.

Brazil is currently the leading exporter of emeralds. Most of the emeralds mined in Brazil are exported to India to be turned into beads because there quality is no match to Colombian or even African emeralds. Africa(Zambia/Zimbabwe), Madagascar, The middle east(Afghanistan/Pakistan), Russia, Australia, Norway, and the USA. Experts agree that Colombian emeralds are the best quality but Zambian emeralds are the runner up.

Nowadays, It’s easy to find high-quality emeralds anywhere in the world with faster-than-ever delivery as long as they find the right supplier.  Original designs and product excellency will shine light upon the future of both buyers and distributors.

 

Don’t even think about buying that Emerald without reading this first!

Most of us are familiar with that experience of walking into a jewelry store and falling in love with a beautiful gem at first sight. In all honesty, this should be the main factor kept in mind while buying any gem; as long as you love it that’s all that matters. Although, here are some important, quick pointers to keep handy to prevent overpaying for your favorite gem, especially if you are buying an emerald. Emeralds, much more than any other colored gemstones, will require these guidelines in order to buy the highest quality emerald for the best price.

Color is the main determining price factor for an emerald.  The vanadium and chromium impurities in the emerald give it its beautiful, fine-green color. The color is made of 3 factors: Tone, Hue, and Saturation. The color grading refers to how light or dark the color of the stone is. The most desirable colors of an emerald are a pure green color or a lucid bluish-green color that is evenly spread throughout the stone and with perfect depth right in between dark and pale. The perfect merger between blue and yellow would create the perfect green hue. The color scale ranges from 0 being colorless up to 9 being extremely dark, and everything in between.

Saturation is the purity and intensity of the hue. A higher grade on the saturation scale will be given to the stone with the more intense hue.

Clarity also plays a big factor in the purchasing of any stone, especially an emerald. The amount and size of imperfections in an emerald play a big role in the price but are permitted in emeralds more than in any other gym because finding an emerald with no imperfections in extremely rare.  Many Emeralds contain Jardins(French for garden) in them which are pieces of other minerals along with fractures and other flaws. To some, the imperfections make the stone authentic and tells the story of its journey from creation to the jewelry store.

The emerald cut is a special cut designed especially to protect the emerald from breaking due to its brittleness and usual imperfections and show off its luxury and beauty at the same time. The emerald cut is a step-cut in a square or rectangular shape with cut corners. Emeralds also come in other traditional cuts such as oval or princess. A professionally-cut emerald will hide the imperfections of the emerald. The “vitreous” status will be given to the best cut, lustrous stones.

The best way to clean an emerald is by using clear oil that won’t damage the color. This is accepted in the jewelry community and usually done at the mining site. Treatment info must be disclosed due to the treatment of the stone lowers its value compared to untreated stones.

Just some easy tips to consider while buying an emerald. But the main factor that should seal the deal is your overall love for the stone.

What is in deed a perfect Diamond??

In order to find the perfect diamond for you, you must consider the 4 c’s: clarity, cut, color, and carat weight. The more you educate yourself about these, the more satisfied with your final product you will be. The perfect diamond would be an IF(Internally flawless) diamond and would have absolutely no color(D-grade colorless). These stones have no visible imperfections and are completely see-through. They are the most perfect, cleanest diamonds. Obviously stones of this nature demand a hefty premium, up to 40% for the same size stone a grade below. This brings up the next question, how far below from perfect are you thinking about going? The Diamond grading scale invented by the Gemological Institute of America, groups[D,E,F] together as colorless, [G,H,I,J] are near-colorless. With the obvious difference in color between D-J, a J grade stone will have a whitish tint to it. The color is graded face-down from one of the sides where the color is more visible and quite frankly it is immensely difficult to tell color flaws between stones with a difference of 1-2 grades. When it comes to clarity, IF(Internally Flawless), VVS(Very Very slightly included), VS(Very slightly included), SI(slightly included). These stones have imperfections that cannot be noticed by the human eye, therefore in some cases, a VS1 diamond could seem as clear as an IF diamond, but not always. The best thing to do is be practical, because of the small differences between grades, it is best to buy a diamond that fits your budget and with overall beauty that appeals you. Just make sure that you receive a GIA certificate and that your diamond is graded correctly and the value not exaggerated.

Meaning of the Stone: January Birthstone
Classification: precious gemstone
Family: Mineral
Region: Russia, Namibia, Italy
Color: light green, dark green
Transparency: Translucent, Transparent
Fracture: Conchoidal
Hardness (Gravity): 6.5-7 (3.84)
Crystal System: Cubic
Similar minerals: Andradite

1. Legend and History:

Garnet minerals have been known and used for many years; Demantoid garnet however was discovered only in 1853, in Russia, more specifically the Ural Mountains.
This gemstone grew quickly in popularity and was considered a beautiful and expensive gemstone which should be treasured by every collector.
Peter Carl Faberge, the famous jeweler had created many magnificent pieces of jewelry with demantoid garnet.

In reference to historical matters, Garnet has been cited in many findings, for example Plato had his portrait engraved on a garnet; Demntoid however has not been mentioned in mythology or history as it is believed that the first ever finding was in fact in 1853.

2. Origin in nature and use:

Demantoid is a green gemstone variety of andradite, which is a mineral of the garnet group. The reason demantoid has its beautiful dark green color is particles of chromium within its chemical formula.

Although demantoid is a green gemstone, it’s appearance in nature ranges from a yellow color to dark green, in some cases even resembling an emerald.
The usual cut for demantoid gemstones is either the emerald cut or cushion cut, as best suited for jewelry.

3. Interesting Facts:

Dematoid gemstones from the Ural Mountains, often have inclusions of chrysolite which look like golden threads that usually curve and resemble a horses tail, thus called horsetails. Horsetails are believed by some to increase the gemstone’s value, this however is probably not correct as they are nonetheless inclusions to a clear stone.

Ametrine

Other Names: Bolivianita
Meaning of the Stone: Birthstone of February and November, as it is a mix of amethyst and citrine
Classification: precious gemstone
Family: Silica, Quartz
Region: Bolivia (although easily found, there is only one deposit)
Color: Violet and yellow
Transparency: Transparent
Fracture: Conchoidal
Hardness (Gravity): 7 (2.65)
Crystal System: Amorphous
Similar minerals: amethyst, citrine

1. Legend and History:

Ametrine is a relatively new found crystal upon which not many historical events and legends have occurred; It is however said to hold the attributes of both amethyst and citrine and combine them with its own unique powers.
It is believed that ametrine reaches to the root of problems, thus allowing for it’s wearer to easily speak and solve his inner problems with people close to him.Furthermore, it’s cleansing abilities are said to dissolve negativeness, and toxins from the body.

2. Origin in nature and use:

Ametrine is a natural mixture of amethyst and citrine; the exact occurrence of the mixture is not fully known in the scientific community, and it may take decades for the exact reason of formation to be known, it is thought however to be formed by a combined effect of high pressure and temperature in deposits which hold both amethyst and citrine, thus causing the later to fuse with the first and adopt a partial area of its color. It is also considered possible that the bi-coloration of the gem is due to a difference in temperature and pressure in the course of one stone meaning in layman’s terms, that only a part of the crystal has heated to the extent to which it adopted the color of amethyst.

Most ametrine crystals are shaped in an emerald cut, however, when one cuts such crystals significant consideration must be given to the percentage of colorations; most gem cutters aim to achieve a 50-50 cut in order to preserve an equal amount of both colors, this method however quickly became too classic for buyers, but also left much ametrine unused.
Furthermore, another fact which must be known in reference to the Ametrine stone, is that much of the ametrine being sold nowadays comes from Russia, and therefore is synthetic; it has many similar physical properties to true ametrine as it is it’s natural counterpart, thus causing difficulties in identification processes. Easily identifiable “fake” ametrine however is that which seems to contain combinations of green and yellow, or light blue, as these colorations do not naturally occur.

3. Interesting Facts:

Ametrine is found in one deposit, that of the Anahi mines, in Bolivia; The Anahi mines received their name in a rather interesting manner. It is said that in the 17th century, a Spanish respected political figure received the mine as a marriage settlement of a princess from the Ayoreos tribe, the Indian tribe which lived in that area; The name of the princess was Anahi.

4. Care and Storing:

As has been mentioned above, only one deposit of ametrine exists, thus the timeframe in which such crystals will be around for is unknown, meaning that owners of such beautiful bi-colored stones should store them safely in a soft presentation box or velvet pouch, and clean the frequently with warm water and a soft cloth, paying attention to the detail, and not using toxic or alcohol based solutions.
