Gemstone Beads: A Journey from Mine-to-Market

For most of gemstone beads lovers, we marvel about how these stunning and precious gemstone beads are formed! While we shop for these precious or semi-precious stone beads to complement splendor to our jewelry and ornaments, the designers and jewelers may introduce us to genuine, treated, or simulated, or a combination of gemstones. Even though at first glance, these might look very similar, their prices vary highly depending on the above categories.

With this article, we attempt to take you along the entire journey of these gemstone beads – right from how they are crafted, colored, how artisans work on their stone cutting, designing, to their trading and retail.

India is one of the leading hubs for gemstone beads manufacturing, followed by countries like China, Sri Lanka, and Thailand. In the modern cities of India exists skilled craftsmen, who are drawn from the patronage of ancient rulers and maharajas. For generations, these artisans have created immaculate gemstones for colorful creations, which are either exported or kept in emporiums and small workshops.

So, how is gemstone beads manufactured in these major hubs?

The manufacturing process of gemstone beads involves raw material, such as gemstones like aquamarine, emerald, citrine, sapphire, ruby, and many more, which are found in various parts of the world. These gemstones are also imported directly from the mines as crude stones for further processing.

semi-precious gemstone beads

To debunk and craft these untreated gemstones to gorgeous beads, artisans convert them into shapes like round, faceted, oval, etc. These natural gemstone beads are subsequently polished by a gemcutter or lapidarist. Most jewelers selling precious and semi-precious gemstone beads use rough gemstones (which are lightly hammered simply to knock-off brittle material) and polish them using progressive abrasion with finer grits of the harder substances. Depending on the size of gemstone beads (as per client’s requirement) skilled craftsmen of a manufacturing unit works on it and creates beads which can be impeccably used in jewelry.

These stones can be further classified as:

Cabochons: these are opaque stone which have smooth and dome-shaped cuts; and 

Facets: these are stones cut with a faceting machine and meticulously polished at regular intervals at an exact angle

Cabochons include turquoise, opal, and variscite. These are peculiarly designed to reflect the surface properties or color of the gem. At times, polishing agents and grinding wheels are used to polish these beaded stones. The facets, on the other hand, are sparkling and transparent and reflect optical properties. To accurately shape faceted stones, jewelers employ experience artisans who can precisely cut these gems depending on their optical properties, for instance, if the angles are too shallow or too steep, it will allow the light to pass through and hence, will not give an appealing look to the viewer. For this reason, some cutters employ elite curved laps to cut as well as polish curved facets.

Generally, the brilliance and luster of gemstone beads are evaluated to determine whether it will be fashioned to a cabochon or faceted piece.

An important point to note here is, the Lab created gemstones (in contrast) are synthetic gemstones that are manufactured in the laboratory. While their physical and optical qualities are similar to a natural gemstone, the technology used for creating them is intricate. And so, these stones are not considered as authentic as an untreated gemstone and calls for an expert opinion to establish its purity.

semi-precious gemstones

Finally, for making eternally fashionable jewelry, jewelers use a range of jewelry tools to bond these delicate gemstone beads for making rings, pendants, necklaces, earrings, etc. Typically, to enjoy the splendor and beauty of these amazing gemstones, artisans use platinum, silver, and gold for making ornaments with precious and semi-precious beads.

To sum up, much of the gemstone beads manufacturing involves methods that are little changed for generations and are worked by artisans following traditional ways to create pieces which were truly fit for the moguls and maharajas of the past.

Getting the Carat weight of gems correct

If you are in the gemstone market, apart from the obvious colour and size, there is one more very important thing that you should evaluate. And nobody is going to cheat you on this if you know how to calculate the size of a gemstone. We all it- The Carat. When it comes to finding the right sized gemstone within a budget you can handle, carats is something you should get familiar with.

What is a carat?

Gemstones are weighed in carats. Every gemologist would count the carat as the basic factor to classify different gemstones. The raw pieces are cut into smaller and smoother edges. The finished gemstones are tagged with the carat after cutting to measure up the amount of wastage in the processing.

Abbreviated to “ct” in a gemstone parlance, a carat is a unit of measurement usually represented in points. A point of a gemstone size is 0.01 of a carat or in general terms, one unit is 1% of what we know as a carat. For very small garnets, rubies and travertine, the usual unit of size determination is a “point” and not carats.

Carat and pricing:

The word “carat” has same origin as that of the word “keratin”. Keratin is derived from the Latin word “keratos”, meaning “little horn”. The carob tree seeds are called keratin too, and the gemstones resemble them in more than one way that you can think of. Carats signify the uniformity of different sized gemstones.

As far as pricing is concerned, a gemstone with higher carat value is quoted at a higher price.

A correlation: Grams versus carat

Until the end of World War I, gemstones were still measured in grams and not carats. After 1920, the popularity of carats caught up owing to bigger sized diamonds being cut into cabochons and smaller shapes. As a method of approximation, gem scientists and lapidary artists zeroed on to carat as an international standard.

One carat = 1/5th of a gram

In general term, one carat is 20 percent of what we know as gram weight.

Law of gemstone pricing:

Price per carat is the universal factor to identify what the gemstone might be weighing. The pricing is fixed as per a very popular hand-rule called “Indian Law” or “Tavernier’s Law”.

In a bid to find the weight of the gemstone in terms of carats, the formula used is:

Carat = Facet style factor (ff) x {Girdle length (grl) x Girdle width (grw)} x depth (dep) x Average specific weight

These days, a specially designed digital scale is used to weigh precious gemstones. The same scale can derive the combined carat weight of more than one gemstone.

precious gemstones

To convert a gemstone’s weight in milligrams into carat, divide it with a factor of 200.

For example, if a diamond weighs 250 milligrams, the weight in carat is: 250/200= 1.25 ct

In terms of points, this carat value is equal to 125 points.

Apart from carat of course, there are three C’s you need to define to arrive at the right price- Cut, Clarity and Colour.

Finishing Methods in the Creation of magical Pearls

Pearl is one of the oldest known gemstones. Along with amber, corals, jets, and ivory, the pearl is the only known organic gemstone that retains its place in the list of precious items in the world. Ivory and coral have witnessed a reasonable decrease in market share, considering the environmental regulations imposed on their extractions. However, as pearls make a wave of adulation across the world, there are some critical points you should know while buying them, especially related to their culture, surface finishing, and commercial selling.

Pearl farming:

Also called as pearl culture, pearl farming is a technology-driven science today. Cultured pearls are grown in controlled biological conditions using different varieties of molluscs. Depending on the family of bivalve molluscs, there are different varieties of pearls.

The pearl oysters used on pearl farming are:

-  Freshwater mussels
-  Marine pearl oysters

It is worth noting the fact that all shelled molluscs are known to produce “pearl” material in some form or the other. It is only the nacre secretion that gives the pearl its signature lustre and value.

Pearl finishing:

Due to the reduced term of pearl culture, the quality has significantly dropped. Thus, it calls for finishing process that gives the pearls their iconic lustre, reflection. refraction and diffraction properties. The degree of translucency heavily depends on the precision of finishing process.

South Sea pearl

Here are some of the accepted finishing treatments done on nacre pearls.

-  Polishing:

It is a common treatment done on pearls coming from the South Sea pearl. The pearl is tumbled in the concentrated brine solution, which removes the layers of mucus and tissues over the surface. Polishing is also done by bleaching the surface to make them appear brighter.

Polished pearls are available in cream, light pink and yellow-brown shades. Unlike natural pearls, polished pearls show better results when polished with abrasive solutions.

-  Maeshori:

Ever heard of heat treatment on pearls? Yes, Maeshori is a unique Oriental Pearl treatment that involves dipping of the Akoya pearls in a methanol solution. It effectively removes all impurities on the surface and also gives it a naturally brighter appearance, resembling the natural ones.

As far as duration of soaking is concerned, a pearl can be dipped in the alcohol solution for as long as 45 days! The treatment not only removes the impurity, but also heals the pearl of its flaws, cracks, and roughness.

-  Bleaching:

A rather corrosive pearl treatment, this is done only to give the surface a more uniform appearance. It is applicable to pearls with thin nacre shell. Pearls with thick nacre are kept away from this processing.

-  Buffing:

Often done to remove visible scratches on the surface, buffing with beeswax and chemical agents is a wasteful method that penetrates deep into the nacre. It is recommended only for minor scratches.

-  Lacquer coating:

Pearls with light lustre are coated with lacquer to improve brilliance. It is a temporary treatment that often wears out. Commercial pearls are coated with silicone polymer coatings, but it not a widely accepted treatment.

South Sea pearl Gemstones

In a nutshell, the cost of pearls drops significantly if there is any visible sign of surface finishing. That’s why natural pearls command a higher price in the market.
