The Story Behind Geshia® Natural Gemstones

 

Reaching To The Remote Places To Get Your Smiles

The gemstones in our jewelry sitting daintily and working their magic are not just about looking pretty; there is much sterner stuff that lies behind that beauty. To ensure that you receive the highest quality of gemstones our gemstones are mined at our own gemstone mines.

In the northern Brazilian states of Minas and Gerais, mother Earth has been gracious to provide us with an abundance of garnets, topazes, amethysts, citrines, peridots and tourmalines. Our exclusive collection of tanzanites, rose quartzes, natural ametrines and lapis lazulis are brought forth from the heart of Earth in Tanzania, Madagascar, Bolivia and Afghanistan.

The sites for mining of these gemstones have been carefully selected after closely studying the geological distribution of these gemstones. Despite these sources being continents apart, there is nothing that wavers the spirit that goes behind providing authentic to our dear customers.

Any article is instantly granted more genuineness if it comes from an area that is naturally gifted with its abundance. This is why we go to great lengths to procure our gemstones from where they are naturally abundant, thus not only ensuring top notch quality but also lowering the cost significantly.

However, our efforts towards ensuring excellent quality do not end here. After their mining, the gemstones are subjected to a rigorous routine of selection and processing.

 

The Birth of Gemstone From Minerals

During mining, a lot of raw gemstones are found and collected but these stones are then thoroughly processed in order to facilitate the selection of quality gemstones.

High Value Gemstone

Garnet

Though garnet deposits are seen in sufficient quantities world wide, there are only a few that are of the quality that can be further used as gemstones.

Contrary to popular belief, garnets come in a huge variety of colors from red to purple. We take efforts not only to sort out these high quality garnets good enough to make jewelry but also make sure that the color is also of a high standard.

Garnets are easily distinguishable from other minerals by virtue of their round and hard isometric crystals. Their specific gravity usually ranges from 3.15 to 4.3 and their surface is usually a variant of the glassy or resinous type. The larger masses of garnets may resemble zircons and tourmalines but we have science to support us! Garnets are distinguished from zircons by their easy fusibility and from tourmalines by their higher specific gravity.

High Value Gemstone

Amethyst

In extracting amethysts, drift mines are made use of. The rock containing the gemstones is reached by digging and then the amethysts are obtained by hand.

The rocks containing amethyst deposits look plain on the outside but on breaking them open, they are like a box holding Earth's precious jewels safe. The rock is hollow from the inside and the amethysts line the cavity.

High Value Gemstone

Blue Topaz

Blue topaz may resemble aquamarine but can be differentiated from it by its orthorhombic crystalline structure. The hardness of the blue topaz which stands at an 8 on the Moh's scale helps in distinguishing it from ruby, citrine and zircon.

High Value Gemstone

Tourmaline

Tourmaline, on the other hand, can be differentiated from other minerals by its three sided prisms that are rare in nature. These are usually triangular in cross section and may be slender or thick prismatic or columnar as crystals.

High Value Gemstone

Peridot

Peridot is the only gemstone that exists in only one color and is formed under tremendous amounts of heat and pressure.

Peridot is often confused with emeralds and green tourmalines. It is then distinguished from emeralds by assessment of color as peridots have a more yellow color and more inclusions and distinguished from green tourmalines by lack of dichroism.

High Value Gemstone

Tanzanite

Though tanzanite competes with other blue gemstones such as blue topaz and sapphire, an experienced person can easily distinguish it because of the lovely hint of purple the stone has.

This gemstone, besides looking superbly elegant has another interesting property; it displays different colors when viewed from different crystallographic angles.

High Value Gemstone

Citrine

The world of gemstones is magical and even impurities create beauty as is seen in citrine because of iron impurities.

Citrine cannot be missed because of its unique color and similar looking stones are either too soft or too hard so nature drops in some helpful clues sometimes.

High Value Gemstone

Lapis lazuli

Lapis lazuli is identified by its distinctive color , non-uniform golden specks and a hardness of 5.5 on the Moh's scale.

Colors - Bringing Gemstones To Life!

According to GIA, gemstone color is the crucial factor to determine the value of a gemstone.The color and brightness matter a great deal and affect 60-70% of the price in the selection of the gemstone in market. In order to deliver the best, we, at Geshia, examine the mined gemstones meticulously and strictly, in different types of light, different angle, for their color to meet our quality standard.

High Value Gemstone

Garnet

Garnets are known to exist in almost all colors with hues of red being the most common and in demand.

The pyrope and almaldine types of garnets range in color from orange to purplish while andradite comes in a variety of greens and yellows and glossular type of garnets comes in the widest range of color ranging from orangish to reddish to green colors.

The beautiful and much sought after color of the garnets is attributed to its nesosilicate structure that leads to contribution of two to three electrons in its structure.

High Value Gemstone

Amethyst

Amethysts have a distinctive purple color and are characterized by the absence of zoning. The presence of bronze colored tint or specks and zones of light and dark lower the value of an amethyst significantly.

Therefore, great care is taken to not pick such stones for our jewelry.

High Value Gemstone

Blue Topaz

Topaz is usually colorless in nature but in the recent years the market has been flooded with the blue variety of topazes; this is due to treatment of the stones as blue varieties are rare in nature.

High Value Gemstone

Tourmaline

Tourmaline occurs in a huge variety of colors; the types that are rich in iron may have a bluish-black color while those rich in magnesium may have a yellowish-brown color.

Tourmaline may also have different colors at its ends which reflects a difference in chemistry of the mineral while crystallization.

High Value Gemstone

Peridot

Peridot is usually yellow to green in color without any traces of brown. The most valued color in peridot is green while the commonly found gemstones are yellow-green in color. Poor quality peridots have a brownish color.

High Value Gemstone

Tanzanite

Though tanzanite competes with other blue gemstones such as blue topaz and sapphire, an experienced person can easily distinguish it because of the lovely hint of purple the stone has.

This gemstone, besides looking superbly elegant has another interesting property; it displays different colors when viewed from different crystallographic angles.

High Value Gemstone

Citrine

Citrine found rarely naturally is highly desirable because of its yellow to orange color and earthy feel to it despite the absence of any brownish tint. However , due to its rare availability, most of the citrines available in the market today are treated with heat to enhance its color.

High Value Gemstone

Lapis lazuli

Lapis lazuli is known for its rich blue color and this lovely intensity is attributed to the trisulphur ion present in its crystal structure.

Clarity In Gemstone, Superiority In Quality

Clarity of a gemstone is an important factor in determining its quality and price. The gemstones are compared against an accepted standard form of clarity because some gemstones such as blue topaz are known to contain lesser amount of inclusions whereas some other gemstones such as emerald have a higher occurrence of inclusions.

Most gemstones usually have inclusions but are not visible to the eye; these can be observed microscopically. Some varieties of garnets are known to usually not have inclusions that are visible by the naked eye.Some varieties of garnets are known to usually not have inclusions that are visible by the naked eye.

Like gmestone color, Geshia looks gemstone clarity an crucial factor so only a very small fraction reach the threshold of quality for Geshia jewelry.

High Value Gemstone

Garnet

Typical garnet clarity depends on garnet type. For example, the red garnets almandine, pyrope, and rhodolite typically do not have eye-visible inclusions. Some of the orange garnets, like spessartine and hessonite, often have eye-visible inclusions.

High Value Gemstone

Amethyst

The Amethysts extracted from Brazil , like our Amethysts have a much lower rate of inclusions visible to the eye. However, color , in case of Amethysts is given precedence though an amethyst with no inclusions and good clarity is considered much more valuable.

High Value Gemstone

Blue Topaz

Blue topaz is often free of any visible inclusions or impurities.

High Value Gemstone

Tourmaline

Tourmaline takes birth in nature in a very liquid rich medium and thus it is common to see a lot of impurities in tourmaline. A hollow tube like impurity can be often seen and bubbling can be seen around it microscopically.

Very often pink and red tourmalines have visible inclusions but these are generally neglected if they have an attractive color but on the other hand , the lighter color tourmalines with visible inclusions are usually rejected or very lowly priced.

High Value Gemstone

Peridot

Peridot usually does not have any impurities that are visible to the naked eye but they may have minute black spots visible under the microscope. Peridot may also have another common type of inclusion , called the Lily pad inclusion which is disc shaped and visible only under the microscope.

High Value Gemstone

Tanzanite

Tanzanite , like blue topaz usually does not have any inclusion visible to the eye thus any such impurity causes a drop in value.It is very rare to find a perfect gemstone with no impurities or inclusions even microscopically but such gems exist and are priced extremely highly.

High Value Gemstone

Citrine

Citrine found rarely naturally is highly desirable because of its yellow to orange color and earthy feel to it despite the absence of any brownish tint. However , due to its rare availability, most of the citrines available in the market today are treated with heat to enhance its color.

High Value Gemstone

Lapis lazuli

In the case of lapis lazuli, the impurities visible to the eye are very rare and hence any presence of them causes a drop in its market value because such inclusions lead to higher chances of cracking.

Evidently , there is a lot of work that goes behind mining the gemstones, processing them , making jewelry people love and bringing them to the market However, with professional knowledge about gemstones and the processes concerning them and cost management , Geshia handles all the tedious yet rewarding aspects of working with gemstone jewelry with great and excitement.
