The Advantages of Man-Made or Synthetic Gemstones



It is just because man-made gemstones are not "genuine" gems; it doesn't mean they aren't attractive. On the contrary, man-made gems have the same intensity like natural gems, and the replications are almost perfect when compared to their usual counterparts.

In fact, their quality is considered high, which it takes them to use exceptional equipment to find out whether the stone is authentic or man-made. They become visible and perfect to the naked eye, and most experts can't even say their distinction without special tools!

What makes man-made gemstones so attractive is that they are tough, available in dozens of exceptional colors-each with absurd spark and shine. Their cost is only in pennies for every carat.

Most gems in the lower price have low production cost compared to the rate of mining, and value that can be controlled tightly. There are various processes used to generate synthetic gems: dissolve expansion, solution growth or high pressure.

There are some regularly used synthetic gemstone materials nowadays which include Cubic Zirconia, Yttrium Aluminum Garnet, Cristinite and Corundum. Gemstones in the world today, roughly estimate 75 to 80% are synthetic or imitated.


Synthetic Opals


Due to opals rarity and difficult mining conditions,synthetic opals have been wildly excepted as a popular man made gemstone.

Opals are one of the most expensive gemstones in the world with red fire selling for tens of thousands of dollars

Many different styles of patterns are available and the block of man made opal can be cut on side to create rare rolling flash pattern which is popular in rings.

Opal Pendants have stunning bright colours that would cost t thousands of dollars per carat if formed in nature.

Many jewelry wholesalers suggest that most people cannot afford opal due to its high cost and synthetics introduce new buyers to the pleasure of opals and one day they might buy real natural opal.

To start synthetic opals are good to appreciate the varieties and patterns of opals referred to a

The queen of Gemstones

Cubic Zirconia

Cubic Zirconia is well-acknowledged as a replacement for Diamonds, due to its sky-scraping solidity and great fire.In fact, it is a synthetic, artificial jewelry or gemstone. In recent years, it has recognized itself as an attractive gem in its own right.

Moreover, it is a fine-looking and man-made gemstone, which is long-lasting, reasonably priced and now even comes in various color of the rainbow, making it even an attractive one.

Fire and Brilliance

Cubic Zirconia has a little brilliance or sparkle compared with the natural diamonds, while having series of rainbow colors. The general effect is so comparable to an authentic diamond that skilled gemologists often entail a special equipment to determine them apart.


Cubic Zirconia has a hardness, which rates from 8.5 on the Mohs' scale. It comes closer to diamond and scratch glass as a natural Diamond.


Cubic Zirconia is weighing 75% heavier than Diamond. CZ's dimension is measured by carats. They are more exactly measured in millimeters, referring to the diameter. A 6.5 mm Cubic Zirconia is equivalent in size to a 1 carat Diamond and roughly weighs about 1.75 carats.


Cubic Zirconia is mostly grown in a laboratory with a controlled environment. If the crystal is not perfect in clarity; it is basically not used for dust or dirt. The optimum CZs are ideal in clarity, but also Cubic Zirconias with diminutive inclusions are available in market nowadays. It is also remain shining clearly with regular cleaning. It is a type of a man-made gemstone that can be worn on a daily basis and will never get dreary or never even transform color.


The finest Cubic Zirconia is engraved into exacting tolerances, which is based on the proportions required with a fine Diamond cutting. Most of the time, thinly cut and faceted CZs will have a refined girdle and more fire.

However, both the stability and transparency of CZ allocating rigorous precision and faceting number of facets in trillion, quadrillion, and radiant cuts are similar to the brightness of natural diamonds.

Laboratory Gemstones


Gemology is not an accurate science and gemstones are demanding subjects. Methodical techniques persisting to develop and change with the existence of modern technologies and fresh challenges are accessible in the market.

After several years, the gemological sciences have developed considerably in extent and technology. The fundamental instruments such as microscopes, refractive indexes, specific gravities, fluorescence and others have been utilized for more than half a century.

Through the use of new treatments in gemstones today, advanced laboratory equipment has been introduced in the field to identify them. Depending on the type of treatments used, the price of the gemstone should reflect accordingly.

Moreover, these laboratories are utilized by the gemstone trade, the public, and the research society. They are devoted to the development of gemstone information and crystal sciences.

Gem laboratories are not perfect, but an international organization such as The LMHC (The Laboratory Harmonization Committee) distributes their research information with respective standards, which need to be rally in order to be part of the organization.

Consistent grading is reliable throughout this group. The status of this organization has a cautious and brief reporting, for such reason; we strongly propose that you can only rely on a laboratory details once it has show detailed information.

Designer Gemstones

Designer Gemstones have become gradually more popular in modern years Most of these gems are offered in cut stones for set jewelry and being offered in the form of beads, which increases the convenience not only for professional designers, but also for crafters and dabblers, as well.

In addition to, it is not only their exquisiteness, but even more for facts that they are natural products of the world that lends to their appeal.Most dealers of gemstones acquire and sell these gemstones per unit of carats. In gemstones, the unit of a carat is 1/5th per gram.

Also, you may be comparing gemstones with different quality and also with a large size stone, which often cost per carat. Also, the kind of cut and the effort involved will play into specific price. The best gemstones are almost always set aside for incise stones to be set in jewelry, a reduced amount of value and rough material is incise also into beads.

For the quality or grading of these gemstones,there is no unlimited and complete standard for grading gemstone It is a one-sided criteria, and eventually up to the seller.Usually, it is graded in an “AAA” or “AA”, or sometimes it is modified by its specific color, size or cut.

The Process of Flame Fusion or Verneuil Process

Flame fusion was the earliest technology utilized for growing gemstones in a laboratory. This method is still commonly used to create rubies and sapphires. The technique is low cost, but the produced gemstones are also low in quality. Gemstones produced with this technique are often used in a low-priced jewelry found in discount retailers and marketplaces.

A competent jeweler must be able to recognize a man-made gem made with this method from the skeletal and tapered grooves that are usually formed as a cool, hard and dissolved material. This was the initial process used for gemstone fusion and is still particularly common.

With small production costs and high crystal growth rates, great numbers of flame fusion gemstones are available. It is the most reasonably priced crystal production technique and offers a reasonable value for money. As a result, it is also widely used to craft the popularly created rubies, sapphires and spinels.

In fact, this method uses the powdered elements of a gem by fusing them collectively under a high-temperature with oxy-hydrogen flame. The ingredient powder dissolves and crystallizes in consecutive layers. This technique opportunely leaves us means of clues, which highly regards its man-made origin.

Important credentials and features of this method are curved resulting from crystallization in layers. These are best practiced under a 10x loupe or microscopic. Although vaguely hard to see, particularly the clouds of gas bubble. The main melt techniques incorporate with the Czochralski's pulling technique and Verneuil flame fusion method, as well.

In fact, Ruby, sapphire, spinel, rutile, alexandrite, strontium titanate and cubic zirconia can be formed by such process. The choice for this particular method depends on the properties of the melting temperature, the required dimension, and the rate of the vessel, particularly when platinum or iridium containers are concerned.

Synthetic Diamonds

For individuals who can't afford to purchase real diamonds or desire a 100-percent guarantee that their diamond is conflict-free, artificial diamonds is a good reserve. Diamonds are considered the hardest material occurring in nature on Earth. Their shine, brightness and toughness have been taken as a staple of the jewelry industry, but they also have some various applications in the modern technology nowadays.

Most of the scientist and researchers have been attempting to expand these diamonds for several decades. Lower rate and the competence of mass production are the reasons behind the research. Artificial diamonds and authentic diamond have been available around since Dr. Moissan naked small pieces of diamond bits, in a hollow part of Arizona in 1893.

The capability to create pure, neutral laboratory, grown diamonds is a topical nowadays. The gems are accessible in several different sources, and can be categorized in four man- made diamond types. Man-made diamonds refer to those crystals that almost similar to a diamond itself, except for being contrived in a laboratory as an alternative of being mined.

The four types of man-made or synthetic diamonds are: HPHT (grit); HPHT (big, single crystal diamond); CVD (polycrystalline diamond); CVD (single crystal diamond). Lastly, the fourth man-made diamond kind is the CVD (single crystal diamond). The creation of single crystal diamond using the CVD method is usually complete on a particular crystal diamond substrate, but other substrates have been utilized - for example, sapphire.

Until recently, existing sizes were classically limited into millimeters in height and used in applications for sensor, electronic, sensor and detector. In 2005, a previous Bell Labs scientist revealed a method to grow CVD single crystal diamonds to the pattern of a neutral, pure diamond. Still working in technology, this modern development has formed a man-made diamond valuable, especially for the industry of the jewelry.

Generally, man made diamond have created a great impact on the earth and will keep on to do so, particularly as technology improves. Scientific studies continue concerning the suitable applications, not only for the jewelry industry, but also for military and business aspects. Decades may still stay behind before a reasonable method can be acquired for mass production of man-made diamonds, but still the search goes on.

The Man Made Gemstones


All the gemstones mined all over the world begun to be depleted with their natural and uneven material. Most of the mine owners are persistently trying to discover latest sources for the purpose of extraction. However, the earth created so much, and supplies are declining.

As a result, the cost for these rough stones is gradually increasing, and it directly affects the price of refined jewelry containing gemstones. However, there is rising demand in man-made gemstones. The first man-made ruby was produced in the late 1800’s using the flame infusion technique.
Shapes and Colors of Synthetic Gemstones

Because of the manner they are made, artificial gemstones may demonstrate slight differences, particularly in their shape and color that help to differentiate them from their usual counterparts. For instance, corundum is generated by flame-fusion, which has curved their growth lines.

In fact, their ingredients have not mixed fully together. Some synthetic gemstones may also undergo from uneven color distribution. Flame-fusion spinel is produced to reproduce gemstones such as ruby, blue zircon sapphire, tourmaline aquamarine, peridot, and chrvsobery.

Man has strived to imitate gemstones for number of years, until in the late 1800’s a considerable success was achieved. During1877, Edmond Fremy, a well-known French chemist identified the earliest gem-quality crystals with its reasonable size and then, the year 1900, August Verneuil set up his technique to produce ruby.

Additionally, Edmond Fremy used the flux-melt technique, which is used to produce emeralds. The powdered elements are melted and combined into a solvent (flux) in a crucible form. The said material must be reserved in high temperature for several months, before being left to cool gradually.

With a small number of modifications, this "flame-fusion" method still exists today. The pounded ingredients are dropped into a heater and dissolve as they reduce through a flame with a certain temperature between 2,000 Celsius or 3630 Fahrenheit, which is in the form of liquid drops. This drip on to a pedestal and crystallize.

As the pedestal is introverted, an extended, cylindrical crystal, which is recognized as a flux - melt technique. Synthetic gemstones are mostly made in factories or laboratories not in rocks. They have practically consisted of the comparable chemical and crystal composition like natural gemstones.

Moreover, their visual and physical properties are identical. However, they can usually be recognized by the distinctions in their inclusions. Several gems have been produced in the laboratory, but only a few are formed commercially, specifically for manufacturing and methodical purposes.
