The beautiful transformation of emerald from ore to gemstone

What is the process of beautiful gemstone emerald from mining to the final end market? Emerald, with the hard work of the miners and the rebirth of the craftsmen, eventually turned into a dazzling jewellery in the hands of the designer. Now follow the inner ginseng to start the journey of emerald exploration, and appreciate the beautiful transformation of emerald from ore to gems!

In general, exquisite emeralds, from mines to markets, initially began with geological exploration and extraction analysis of ore samples.

Small independent mines will manually clean the gravel to analyze the mineral content of the emerald in the sandstone to guide people to determine the specific location of the emerald vein.

In the world, few emerald mines, like the Belmont mine in Brazil, can always use open-pit mining to produce high-quality emeralds.

The gemstone containing the gemstone is loaded onto the truck for further processing.

Washing out the gems with water is a necessary step. Large mine owners often use high-pressure water guns to clean the sand and separate the emerald rough.

The Belmont mining area uses a complex pipeline separation method to separate the ore from the sediment.

The slightly heavier ore containing emeralds remains on the conveyor belt and enters the final separation procedure.

In addition to Belmont, other colored gemstone mines rarely use optical sorters to identify and retain ore containing emeralds.

The ultimate goal is to find emerald rough that has the processing value, improve efficiency, and finally reach the market and meet buyers.

However, many emerald mining areas still use underground methods to drill emeralds in hard rock using drill holes and explosives.

After drilling holes in the rock, put the explosives, and then prepare to detonate the ore. If the explosives are not used, the mining will take longer and more labor.

Large underground mines often use heavy machinery bulldozers to load ore into railcars.

Mechanization greatly increases transportation efficiency, so the potential production of emeralds also increases.

When the railcar is full, it will move along the track to a place where it can be directly loaded and transported out of the mine.

A little better is to use the winch to drag the track trolley, while in some simple mines it is to use human traction.

At the Piteiras mine, the miners dump the ore from the railcar directly into the transport well above the transport truck.

Once the transport truck is in place, the silo door that transports the well is opened, and the gem-bearing ore that has been poured above flows into the truck with the funnel-shaped pipe.

Along the ramp-type mining road, the transport truck is loaded with ore and leaves the mine area for the next process.

The mined ore is passed through a washing system and screening system on a conveyor belt to classify the stones by size.

However, most mines use artificial methods to classify the stones on the conveyor belt.

Workers are skilled and carefully sorted to avoid missing any pieces of emerald-containing stones.

Finally, the emerald rough is usually wrapped in the main rock and still needs to be re-discriminated and summarized.

Some small independent mines often separate emeralds and rocks in a more primitive and time-consuming manner.

Almost the use of emerald ore was found by manual hand washing, separation and selection.

This production is much smaller than mechanization, but a few lucky miners have improved their lives through their efforts.

Such independent mines are spread all over the world, and they also provide a large number of colored gemstones including emeralds for the jewelry market.

After a day of hard work, the emeralds can give those independent miners and family a sense of peace of mind and the continual search for emeralds.

Many independent miners sell the harvested emeralds to larger miners, or to local jewelry brokers (to the market for sale, extract commissions).

The Belmont mine owners have their own buildings in Itabira, Brazil (south-eastern Brazil), where they classify emerald roughs by grade and provide them to customers around the world.

The final step is in the fine removal area where the emerald rough is manually removed from excess impurities and blemishes.

After the rough has been trimmed, the emeralds are sorted according to size, shape, color and clarity.

Most of Belmont's customers are gemstone cutters who have a variety of sizes and quality requirements, and Belmont carefully categorizes the gemstones to meet the individual needs of the client.

Fine rough classification leads to higher market prices.

When the emerald rough is sorted by fine grades, those cutters can more easily pick out the range of gemstones and qualities they need, and make it easier to complete the list of gemstones they need.

Even small rough stones are carefully sorted according to the shape and quality level as required.

The assorted good emerald rough is ready to be cut into perfect gems by the jeweler.

After sorting, the rough must be inspected and the cut shape and orientation determined to ensure the most weight of the gemstone is left. The cutter must also decide which cutting method to use to retain the maximum gem weight.

The cutting process is determined by the cutting master where to start cutting.

After cutting, the next key step is to polish the rough to its original shape, called preforming. This stage determines the final result of the positioning, shape and weight of the gemstone.

After preforming, it is to cut the facets. This stage determines the brilliance and polishing quality of the gemstones, as well as the release of the potential glamour of emeralds.

The cutter will create the best light refraction angle for the gem pavilion, allowing the maximum refraction of the light to return, avoiding the light leakage window.

The cutter needs to constantly check each section to ensure that the angle and symmetry after polishing are absolutely accurate.

The final polishing will create brilliance and sparkle, which is also an intuitive condition to attract buyers' attention.

Emeralds range in size, but gemstones are often cut to the typical size specifications of the industry, not the maximum weight, which will result in a higher price per karat.

In the offices of all cutters and wholesalers around the world, the product list is constantly categorized and updated to meet the various requirements of the customer and to prepare for various trade shows.

Sometimes emeralds don't need to be sold far away, there is an important trading venue in Brazil - TeofiloOtoni, MinasGerais.

StoneWorld is a gemstone company that combines mining, cutting and wholesale to bring emeralds from the mine to the jeweler.

This set of matching emeralds will be sold to jewelers who can use them to create a delicate emerald necklace.

These emeralds from Colombia will go to Tucson for sale. There, jewellery manufacturers and retail wholesalers make purchases and sales, or retailers buy them directly on custom jewellery.

At the exhibition, more and more colored gemstones will be sold as the final process of the finished jewelry.

Those high quality single quality emeralds are often designed as the material of choice for private custom jewellery.

The final design is often the most important part, and the final design template will be presented to the wealthy customers who have the willingness to buy at the best retail salons in the world.
