Secrets Diamond Simulants are the most perfect diamond simulant, indistinguishable from a diamond with the naked eye.
They’re cut by master craftsmen to the exact proportions and standards demanded by the diamond industry to ensure each stone has maximum brilliance and fire. Years of research and development by gemologists have produced a stone of such quality that it's indistinguishable from a diamond with the naked eye. Secrets Diamond Simulants are grown in a state of the art laboratory from the natural mineral base zirconium oxide and this revolutionary stone is produced using intense heat and only the most perfect material is chosen for the finished product. As a result, Secrets Diamond Simulants have a hardness of 8.5 with a diamond measuring 10 on the industry standard MOHS scale.
Secrets Diamond Simulants are guaranteed to retain their beauty, colour and brilliance forever and this lifetime guarantee is our promise to you. Your stones will be replaced complimentary for discolouration or loss of brilliance under normal wear.
Diamonds and Secrets Diamond Simulants are valued on four criteria: colour, clarity, carat and cut.
Colour is graded alphabetically from D to Z, with D being the absolute finest colourless stone rating in the world. The presence of trace elements, such as nitrogen, within the atomic framework of the carbon crystal may influence the colour of a stone. Discerning the difference between each grade of colour is extremely difficult even to an expert. Secrets Diamond Simulants are equivalent to D or E colour when compared on the diamond colour scale due to the superior quality of the material used.
Clarity is determined by the levels of imperfection in a stone. Almost all diamonds have very tiny internal marks (inclusions) and external irregularities (blemishes). Many inclusions are not discernible to the naked eye and can only be seen under magnification. A diamond can be described as "flawless" only if it has no visible imperfections when viewed under 10X magnification by a skilled diamond grader.
The weight of a diamond is expressed in carats. The word carat originates from the seeds of the carob tree, which are well known for their uniformity and consistent weight. Historically diamonds and gemstones were weighed against these seeds. Nowadays it is a bit more scientific. One carat is defined as one-fifth of a gram or 200 milligrams and because the carat is a measure of weight rather than size, two stones that have identical carat weights may actually appear very different depending on their exact geometry, proportions, and shape. In general, compact shapes such as round diamonds appear to be the smallest based on a comparison of carat weight and visual size, whereas longer gems such as emerald cuts or marquise shapes maximize the stone’s table with the illusion of greater size for the same carat weight.
The specific gravity and weight of a Secrets simulated diamond is heavier than a diamond so we measure our stones in millimeters and cross reference that to a diamond carat size eg: 6.5mm diameter simulated diamond is the same size as a 1 carat diamond. Therefore our carat equivalent weights referenced on our jewellery is an estimated equivalent diamond weight based on measurement.
Whatever the size and shape of the raw material, a well-proportioned and well cut diamond optimizes refracted light which creates brilliance and fire. Diamonds are cut with facets, or separate flat surfaces, which follow a mathematical formula and are placed at precise angles in relation to each other. This relationship is designed to maximize the amount of light refracted through the diamond and thereby increase its sparkle and beauty. Secrets Diamond Simulants are cut using exactly the same methods as the diamond industry. Secrets use only the best master craftsmen and polishers to make sure every stone is cut to perfection.
Secrets round brilliant cut stones all possess 58 facets and are cut with a hearts and arrows pattern. This is a high standard of cutting due to the loss of weight from the rough and the time taken to perfect it. When viewed from above and below hearts and arrows are seen as a series of eight gray arrowheads with intersecting hearts - these are highlighted on the diagram below.
Secrets also create an array of sparkling coloured stones that are then cut by master craftsmen to the same exact proportions and high standards as our white stones.

Secrets jewellery is designed and crafted by a team containing some of the world's most talented master jewellers, setters and polishers that have a long track record of producing jewellery of the highest quality to exacting standards. Our signature designs are created from 14ct or 10ct Gold or sterling silver. We can specially make any piece from our current range should you find it unavailable and this will take approximately 6-8 weeks or 8-10 for rose gold. This excludes any limited release or seasonal items. Some styles in particular sizes will require a new master pattern to be created which may incur an additional fee.
Secrets designs come in an array of stone shapes and the information below shows you the history and inspiration for those shapes.
The Asscher cut is a unique design created specifically for the Dutch Royal Family in 1902. It has an almost octagonal shape and was a departure from the popular brilliant cut of the 1800s and it became the forerunner of the standard Emerald cut. Its beauty however is breathtaking due in part to the angled corner facets which gives it a look of an inverted pyramid. It is also commonly attributed as having an Art Deco look which confers real class on the style.
The cushion shape is an antique design that evokes the glamour of the 1920s. Charming and opulent, its rounded shape is similar to a round, but more distinctive. The shape was often referred to as the Pillow Cut due to its slightly rounded sides. Cushion cut stones are romantic, elegant and luxurious.
The Emerald cut includes what are called “step” cuts. These comprise larger facets, which act like mirrors. There are fewer facets than most other cuts and because of the size and shape of these, the emerald cut shows less sparkle than the brilliant cuts. The emerald cut however, has a classic beauty and elegance quite distinct from the fire and brilliance of others.
The Heart shape is also a brilliant cut and sparkles accordingly. It is essentially a pear shape with a cleft at the top containing 59 facets. Its enduring appeal is in its elegance and as the eternal symbol of love. The heart shaped stone is particularly popular for romantic occasions such as Valentine’s Day or anniversaries.
The Marquise cut is another adaptation of the 58 faceted round brilliant cut. This shape complements long slender fingers particularly well. 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. Marquise cut stones have an elongated shape with pointed ends supposedly inspired by the smile of the Marquise de Pompadour and commissioned by the Sun King, France’s Louis XIV.
The Oval shape is also brilliant cut, borrowing the same faceting techniques from the round brilliant although additional facets are added to assist in the elimination of the “bow-tie effect” in the mid-section of the stone. The oval cut is sophisticated and ideal for someone who values elegance but is after something unique. Oval cut stones are equally flattering for shorter fingers, as they create the illusion of length.
The Pear shape is also brilliant cut, except the proportions are elongated along the tip. One of the keys to cutting a beautiful pear shape is the reduction of 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 (called “French Tipping”) to counter light leakage in the area. The pear or ‘teardrop’ can be worn facing either way creating different looks. This is a truly show-stopping cut for those who want to stand out.
The Princess cut combines the high degree of light return of a round brilliant cut with a distinctive square shape. The princess cut is relatively new being created in the 1960’s. It often finds its way into solitaire engagement rings or earrings and is a design well suited for long fingers. All Secrets princess cut simulated diamonds are double faceted to increase the sparkle.
The Radiant cut has 70 facets and is a variation of the brilliant cut. The crown (top)section has a combination brilliant-step cut arrangement and the pavilion section has more of a brilliant styling with a slight step-styling in the upper sections just below the girdle. This is a supremely elegant style and the rectangular proportions lend themselves to many different styles of design.
The most popular stone shape is the round brilliant, which came into existence roughly 60 years ago. It’s an adaptation of the brilliant cut, created in the early 18th Century, and remains the most popular cut to this day. It suits absolutely every woman with its sophisticated brilliance and fire.
The Trilliant cut is, as the name suggests, cut in the shape of a triangle. It possesses sides equal in length and usually contains 50 facets and is particularly popular as side stones in beautiful dress ring designs.
