Gemstone Guide

A gemstone is a beautiful commodity to own, they come in a form of mineral or a rock. Gemstones have been collected by connoisseurs for generations and play an important role in investments today. But investments aside gemstones are just beautiful and at Magnons we make a lot of jewelry with gems be it an engagement ring or a cocktail ring. If you are thinking of purchasing a gemstones or creating a custom piece make sure you read our guide first to make the right decision on your new purchase!

Gemstones are available in many colors however most people prefer them facetted as they are much prettier cut and polished than in their rough state.

On the basis of its formation, gemstones are classified into five categories:

NATURAL — Natural gemstones are formed in a natural environment with no interference by a human being. They form by different chemical compounds that contribute to their color, hues and luster.
GENUINE — Genuine Gemstones are natural gemstones which are treated in some way to enhance their appearance, the stone is still a natural stone but there is a small interference by a human being.\
SYNTHETIC — A synthetic gemstone shares the same properties as the natural gemstone such as physical and chemical qualities however it was created in a laboratory. These stones are often called: Manmade, lab created, lab gems.
IMITATION/SIMULATED — Imitation gemstones are often made of glass or plastics and do not share the same qualities as the natural gem. These are super easy to detect for any jeweler. Imitation gems are often called simulated and cost much less than any of the above.
TREATED — Treated gemstones are enhanced with either clarity or color ot make the appearance of the gemstone more desirable and competitive. This can be heat treatment, irradiating and various laser techniques. A lot of treatments are not permanent and may go back to its original state after some time or an application of other chemicals, for example if perfume gets into contact with a treated gemstone it can fade in color. Treatment should be disclosed and treated gemstones often cost less depending on treatment however sapphire for example is most always treated with heat, today this is a normal procedure as the natural sapphire that comes from the earth is a lot less vivid in color. The heat enhances a natural color in the sapphire and is almost never disclosed because it is normal for the industry. However clarity enhancements devalue the stone a lot so please ask when you purchase a gemstone of any treatments present or ask for a certificate of authenticity.

Gems are dependent on certain characteristics when it comes to desirability and value. Please see characteristics below to consider when buying a gemstone.

BEAUTY — A gemstone is valued based on color, size, shape and sparkle. The most important in a gemstone is how it look so color and sparkle give a bigger importance than clarity or shape.
HARDNESS — Sometimes the most beautiful gems will not make it to an engagement ring because of the hardness level. We all know the durability Mohs scale(below) and that diamond is the hardest material. Some gemstones like sapphire and morganite are popular for a reason, they are not only pretty but also durable for everyday wear. Please find out how durable your gemstone is before purchasing it.
RARITY — Rarity is also desirable for a gemstone, one of the biggest factors for value. The rarity of a stone imparts a sense of exclusiveness and worth that increases our desire to possess it, for example an appraisal value often is based on this because if you were to lose the gemstone it has to be replaced and that is quiet often impossible as the nature doesn’t make the same match in some gem categories. Rarity determines the prices placed on gems and famous jewelry all over the world.
FASHION — Often, there are spikes in sales for jewelry or gemstones that are desirable and often desirable because of media, a good example are salt and pepper diamonds. We have known them for years but their popularity spiked up only in the recent years due to awareness, media etc. The fashion plays a big part in jewelry and gems and their prices can sky rocked because an actress got proposed with a certain style or diamond.

Gemstone Guide

This Gemstone Education defines the six most essential characteristics of Gemstone along with tips for its care. By understanding these characteristics, you’ll be able to make a conscious decision when purchasing a gem or that gemstone engagement ring you were eyeing.

Care

COLOR

The color of a gemstone is its most significant often because the nature made this color and it might just be that there is no other comparable gemstone of the same color. The color plays a very important part and divides into hue, saturation and tone.

Hue

Hue is the primary or unique color of the gemstone. You can call it the basic color, almost all gemstones come with array of colors but the most desirable are the ones that show one color.

Saturation

Saturation is a measure of the intensity of a gem’s hue or color. The better the saturation the more valuable the stone.

Tone

Tone represents how dark the color is from light to dark. For example, a sapphire which is light is a very pale color and the one that is dark looks almost black. This means that the tone is representative how dark or light the stone is.

CLARITY

Clarity is a term used to describe the flaws inside or on the surface of a gemstone. A flawless gemstone is very rare and thus very pricy, however this is only true if the gemstone comes from a family of included gemstones. For example, to find a clear amethyst or a citrine is very easy and even if flawless it would not cost that much however to find an emerald flawless would be very hard and thus would be very expensive. Why? Because emeralds are quiet included by default whereas quartz is not included by default. Most gemstones have inclusions, or tiny mineral flaws, that can be seen under microscope or under a loop. A gemstone may have inclusions, spots, clouds, cracks, zoning, feathers or even bugs amongst all imperfections.

Clarity is the second biggest characteristic to consider when buying a gemstone. The concept is the same as diamonds, the less inclusions the better however in colored stones the inclusions can be seen with a naked eye and still be very expensive as there are other factors that would sky rocket the gem price.

For clarity in gemstones we use three categories TypeI,II,III this is similar to diamonds scale (F) being flawless to Included (I3)

Type I

Type I colored stones include stones with very little or no inclusions by default. This category can include Aquamarine, Topaz, Tanzanite, Zircon, Morganite etc.
Clarity in the Type I group is classified as VVS (minute to detectable), VS (minor), SI1 (noticeable), SI2 (obvious) or I (included)

Type II

Type II colored stones include stones that often have a few inclusions by default. This category can include Sapphire, Ruby, Garnets, Iolite, Peridot, Quartz (Amethyst, Citrine, Ametrine), Corundum, Spinel, etc.
Clarity in the Type II group is classified as VVS (minor), VS (noticeable), SI1 (obvious), SI2 (prominent), or I (prominent, affecting appearance).

Type III

Type III colored stones includes stones that usually always have inclusions. This category can include Emeralds, Tourmaline, etc.
Clarity in the Type III group is classified as VVS (noticeable), VS (Obvious), SI1 (prominent), SI2 (more prominent), or I1 (affecting appearance or durability).

Cut

Good cut is something that may give a gemstone its natural beauty and brilliance. A gemstone’s cut refers to its proportions and symmetry. The stone should be symmetrical in all dimensions so that it will appear balanced, and so that its facets will reflect light evenly, which will provide good brilliance to stone. The brilliance will be maximized if the light travels fast through the stone. A well-cut faceted gemstone reflects light back evenly across its surface area when held face up. If the stone is too deep and narrow, surface area will be dark and if it is too shallow and wide, parts of the stone will be washed out and dull.

While cutting, color of a gemstone should also be taken into account for optical efficiency. If a stone’s color is highly saturated, a shallow cut will allow it to pass more light, while a deeper cut may increase the vividness of a less saturated gem. There is no generally accepted grading system for gemstone cut.

CABOCHON Cut — In the cabochon cut, the upper surface of the stone is smoothed and rounded into a simple curve while the bottom could be faceted or flat.
TABLE Cut — In the table cut, the facets of the natural octahedron of the diamond are ground to smoothness and polished; one facet, the table, is ground much larger than any other and made the top of the gem, while the opposite facet, the culet, is left quite small.
ROSE Cut — The rose cut consists of a flat base and (usually) 24 triangular facets—resembling a cabochon with facets.
BRILLIANT Cut — The brilliant cut is scientifically designed to bring out the maximum brilliancy of the stone. The crown of a brilliant consists of a table and 32 smaller facets, of which 8 are quadrilaterals and 24 are triangles; the base, a culet and 24 larger facets, of which 8 are quadrilaterals and 16 are triangles. The base and crown are separated by a girdle. The brilliant cut has certain proportions—in general, the depth of the crown is one third the depth of the stone and the width of the table one half the width of the stone.
OTHER Cuts — There are many different cuts such as old european, old mine, single cut, square, triangular, emerald, step, trapezoid,square, triangular, step and many more.

The process of cutting and polishing gems is called gem cutting or lapidary, while a person who cuts and polishes gems is called a gem cutter or a lapidary. Few gemstones such as pearls and coral (usually referred to organic minerals) are not cut at all and many times left in their natural state. However, it is customary to polish these items, as with all gemstones. The quality of a gemstone’s cut can have a dramatic impact on how it looks but only a small impact on the price per carat because the color and clarity means more.

Size

A gemstone’s weight is also measured in carats (like a diamond) where one carat equals 200 milligrams. Different types of stones have different densities and thus two gemstones of the same carat weight may be completely different in size. For example, 1ct emerald will be smaller than 1ct ruby because the emerald is less dense than a sapphire or a ruby. Gemstones can also be measured in dimensions (diameter, length, and width).

Illustration of gemstone dimensions and cut (insert)

Much unlike diamonds, the gemstones are not more valuable with size or can be valuable but not necessarily. For example amethyst of a large size is not uncommon thus is not rare and not that valuable but an emerald of a large size will cost a lot of money because its more rare and harder to find on the market.

Enhancements

Gemstone Enhancement is a treatment process other than cutting and polishing that improves the appearance (color / clarity), durability or availability of a gemstone. This treatment covers heating, oiling, bleaching, irradiation, waxing, dying and others.

There are many ways to enhance the appearance and durability of gemstones. Some of these treatments or enhancements, are permanent where as others are temporary. Gemstone enhancement has become such a common as well as accepted practice that experts believe the vast majority of stones are treated in some way. It’s important to remember that most gemstone enhancements greatly improve the appearance – and hence the value – of a stone.

All gemstones can be present with the following:

N – The ‘N’ symbol appears on the chart only for natural stones which are not currently known to be enhanced
E – The ‘E’ symbol appears on the chart only for those gemstones, which are routinely enhanced.
Third category covers those gemstones which are treated in a non-traditional manner.

Chart for Gemstone Enhancement Information

B – Bleaching: The use of chemicals or other agents to lighten or remove a gemstone’s color. Pearls and ivory also may be bleached to lighten their color.
C – Coating: The use of such surface enhancements as lacquering, enameling, inking, foiling, or sputtering of films to improve appearance, provide color or add other special effects.
D – Dyeing: The introduction of coloring matter into a gemstone to give it new color, intensify present color or improve color uniformity.
F – Filling: As a by-product of heat enhancement, the presence of solidified borax or similar colorless substances which are visible under properly illuminated 10X magnification.
G – Gamma/Electron Irradiation: The use of gamma and/or electron bombardment to alter a gemstone’s color; may be followed by a heating process.
H – Heating: Heating is one of the most common treatments used to enhance the natural beauty of colored gemstones. It is a permanent process that can dramatically improve the color and/or clarity in a number of stones, including sapphires, rubies, diamonds, aquamarine, amethyst, tanzanite, topaz, tourmaline and other stones.
I – Infilling: The intentional filling of surface breaking cavities or fractures usually with glass, plastic, opticon with hardeners and/or other hardened foreign substances to improve durability, appearance and/or add weight.

Care

Do not spray the parfume or cologne or hairspray directly onto jewellery this will damage most gemstones in a long run as they are much more sensitive than a diamond.
Do not wear it when cleaning, washing dishes, gardening, gym, yoga, pool or spa as all those things will not help maintain the gemstone or jewllery piece.
Do use soap water and cloth to clean your jewellery regularly, you can even use a tooth brush and water and soap to clean your jewellery.
Do use professional jewelery places to clean your jewellery once a year as they have the machinery and tools to do it with the most care and professional knowledge.

Storing your jewelry:

Please store it in a dark place preferably in cloth or separate bags as the jewelry should not touch another jewelry piece not to scratch each other. If you are storing it together make sure the space gets dark as the sun can have a negative impact on gemstones.

Gemstone Guide – Precious and Semi-Precious gems

Precious Stones

Gemstones which are highly valuable for their hardness and rarity, are known as Precious Stones. Precious Stones are generally expensive in comparison of Semi-Precious Stones. There are only four Precious Stones:

The name Opal is derived from three sources: Sanskrit ‘Upala’, Latin ‘Opalus’, and Greek ‘Opallios’. All three of these words mean the same thing – precious stone.

Opals come in many colors, including black, white, gray, yellow, colorless, orange and red. Red is considered the most popular and attractive colors that Opal comes in. There are usually two types of red colors – cherry red and fire red. Fire red is usually the most popular and possibly the most expensive due to its wonderful hue and rarity.

Australia is the major supplier of Fine Opals and almost 95 per cent of all Opals come from Australian mines. Opal is made from sand and water. It has the same chemical formula as quartz with the addition of 3 -10 % water content. And due to this reason, opals must be protected from harsh light and heat, which could dry it out and cause cracks. Opal is relatively less hard than many other stones and must be worn with caution and care to avoid chips or other breakage.

For producing cultured pearls, shell beads are placed inside an oyster and the oyster is returned to the water. When the pearls are later harvested, the oyster has covered the bead with layers of nacre. The finest Natural Pearls are fished almost exclusively from the Persian Gulf and the China Sea. Fine Natural Pearls are much more expensive and rare to find than Cultured Pearls.
