While we agree that nothing sparkles quite like a natural gemstone, we are also certain that you will not find a better alternative than CARAT*. Many jewellers have admitted that they have difficulty telling our gems apart from naturals because of their very similar optical characteristics.

It takes around nine months to train a single technician in the stages of sawing, pre-forming, faceting and polishing CARAT* gems. In fact, each stage of the process from beginning to end is the same as those found in fine jewellery making. Each step is performed with precision and care, so as to achieve the ideal proportions that will yield the most brilliant CARAT* stones.

We hand and precision machine cut every stone with meticulous attention to detail, each stone is then individually polished by hand. Because we only use highly trained and experienced stonecutters, we create high-quality gems that are second to none.



Measuring an impressive 8.5-9.0 Mohs (the scale of mineral hardness), with only diamond measuring the maximum 10 Mohs, our stones are close to sapphire and ruby in terms of hardness. Whilst being very durable, our stones still demand the same respect you would give their natural inspirations. Keep them clean and try not to knock the mountings and they will last a lifetime.



All our stones normally exceed Gemological Institute of America (GIA) accepted “Ideal” cutting tolerances. By doing this we ensure they are some of the most beautiful simulants in the world.


Normally when scored against the GIA diamond colour scale, our stones are an equivalent of D or E in colour (D being the very top of the scale).

Clarity Comparison:

Typically we yield a clarity of "IF" (Internally Flawless) although VVS1 (Very Very Small Inclusions) can be noted in some larger CARAT* stones. The vast majority of CARAT* stones will appear flawless to the naked eye. By definition, you will need a jeweller's Loupe to see inclusions in CARAT* stones.




The Round Brilliant, or Brilliant Round, is what comes to mind for most people when they think of a diamond. It is one of the simplest yet most dazzling expressions of a cutter's wheel. With 58 facets to refract and reflect light on, the round brilliant cut represents the most popular form of cutting in the 21st century.


Second in popularity to the Round Brilliant is the Princess cut. Slightly modified from traditional cutting, it reveals the true potential of its brilliance. Full of fiery scintillation, Princess cut stones burst with reflected light.


Another Brilliant cut, Pear cut stones bear many of the facets of a round except their proportions are elongated along the tip. One of the keys to cutting a good Pear shape is reducing the bow-tie effect that appears in the lower mid section of the stone. Additional facets are also added to the tip of the stone, known as French tipping. This facets counter light leakage in the area. Through superior cutting techniques, we have been able to achieve a brilliantly proportioned Pear that will outshine most others.


Yet another Brilliant cut, Oval cut stones borrow faceting techniques from the Round Brilliant. Additional facets are added to eliminate the bowtie effect in the stone’s midsection. The overall effect is a stone that is more often seen as the exclusive domain of the very rich, since they look a little different from the ubiquitous Rounds.


This stone is another adaptation of the 58-facet Round Brilliant. Previously the domain of royalty, Marquise cut stones have a unique shape that particularly suits long, slender fingers. The crown is modified in the Marquise to form what is called a French Tip, where the bezel facet at the point of the stone is eliminated. This allows a more even spread of scintillation along the length of the stone.


The Emerald cut is classified as a step cut; with larger facets, which act like mirrors. The Emerald cut has fewer facets than most cuts. Because of the angle, size and shape of the facets, the Emerald cut shows less brilliance and fire (dispersion) than other Brilliant cut diamonds. However, the Emerald cut stone reveals a sense of classic beauty and elegance not seen in other cuts.


Our Radiant cuts have 70 facets and the stone is truly one of our most brilliant cuts. The crown section includes a Brilliant and Step cut arrangement. The pavilion section of each Radiant cut stone is styled similarly to Brilliant stones in that they have a slight step styling in the upper sections just below the girdle. The overall look is one of bewildering light and colour.


The shapes of Asscher cut stones are nearly identical to those of Emerald cut stones, except that they are square. Asscher stones also have pavilions that are cut with rectangular facets in the same style as the Emerald cut. The original Asscher cut was very popular in the early 1900s, before the Great Depression. The eventual invention of modern diamond sawing machines, however, made them uneconomical to cut. Nonetheless, their beauty is breathtaking and thus the cut has been revived and improved with the addition of 16 extra facets that add even more brilliance and life to this outstanding cut.


Another Brilliant cut and a slight variation of the Pear cut, Heart cut stones have a small slice removed from their top sections, revealing a sparkling symbol of love. Our attention to detail ensures that the removed section is also hand polished for maximum brilliance. Something you will find lacking in many other simulants.


Starting in 1830, the Cushion cut became one of the most popular cuts. For 70 years, until the early 1900s, most diamonds were cut in this style. The Cushion cut is often referred to as the "Pillow" cut because of its slightly rounded corners. The Cushion cut was cut to sparkle in candlelight, which was common in that era. Till today, Cushion cut diamonds continue to hold their own in a room full of Round stones.


This cut is an example of a modified Round Brilliant, and as a result, it is comparable, if not superior, to the best Round cut or Princess cut diamonds. It is becoming a more popular way to cut rough diamonds as it yields a relatively higher carat weight than equivalent Round Brilliants or even Princess cuts.

In keeping with our tradition of offering the finest simulants in the world, we also offer simulant fancy colour and lab created stones. By selecting from the stone colour menu on the item screen our craftsmen offer you the option to select and mount our AAA grade beautiful lab-grown sapphires, rubies and emeralds as well as other fancy diamond colours such as Canary Yellow, Champagne and Fancy Pink.


Diamond White CARAT* gems follow the long history of folklore that have been attached to diamonds for centuries. Often regarded as the ultimate gift and a symbol of eternal love, diamonds are still and will continue to be admired all around the world. While we agree that nothing sparkles quite like a natural gemstone, we are also certain that you will not find a better alternative than CARAT*. Many jewellers have admitted that they have difficulty telling our gems apart from naturals because of their very similar optical characteristics. Normally when compared on the GIA diamond colour scale, our stones have an equivalent D or E colour (D being the very top of the scale).


The name "Sapphire" is derived from Greek word sappheiros, which is Greek for blue. Since Ancient times the Sapphire Blue represented a promise of honesty, loyalty, purity and trust. Up till today, Sapphire Blue gems are one of the most popular gemstone colours for engagement rings. In keeping with this tradition, our brilliant Sapphire Blue CARAT* gems share a similar colour richness with their natural inspirations.


Ruby Red represents love, passion, courage and emotion. For centuries, it was believed that wearing a fine red Ruby bestowed good fortune upon its owner. Rubies have been the prized possession of emperors and kings throughout the ages and CARAT* gems were made to carry this same aura of luxury.


Emerald Green is the colour of spring and has long symbolized love and rebirth. As the gem of Venus, it was also considered to aid in fertility.

Cleopatra, Egypt's tempestuous female monarch was as famous for wearing Emeralds in her time as Liz Taylor is for wearing diamonds in our time. Ancient Egyptian mummies were often buried with an Emerald carved with the symbol of verdure – flourishing greenness – on their necks to symbolize eternal youth. Emerald green CARAT* gems add a pop of lavishness and timeless beauty to any look.


Fancy Yellow gemstones symbolize wisdom, joy, optimism, happiness, and youth. Of all the Fancy Coloured Diamonds, Fancy Yellow Diamonds are the most popular. In the same vein, CARAT* Fancy Yellow gems display a youthful exuberance and are admired for their utter brilliance and beauty.


Champagne coloured gems are a wonderful choice if you are looking for something special yet subtle. CARAT* range in colour from Chocolate to light Champagne. Though Champagne CARAT* gems display an understated beauty, they in no way compromise on shine. The subtle hues and rarity of Champagne gems make our Champagne CARAT* gems an attractive choice for a women seeking a modern Fancy coloured gemstone.


Pink gemstones never fail to provide head-turning bursts of colour. Fun and fanciful, they are femininity incarnated. Pink is said to symbolize gentleness, love and affection. Gifting yourself or a loved one with Fancy Pink CARAT* gems is perfect for occasions that mark the coming of a bright and "rosy" future.


The most sought-after colour of Fancy Sapphires is the rare and beautiful Padparadscha: a pink-orange gem with a distinctive salmon colour reminiscent of a tropical sunset. Pink Padparadschas are ultra-rare and are among the most coveted gems in the world. We have captured the beauty of these natural inspirations with our Pink Padparadscha CARAT* gems which effortlessly emulate their warm and glowing magnificence.
