Our Stones


Secrets Diamond Simulants are the world's most perfect diamond simulant.
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 flawless 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. Secrets Diamond Simulants are flawless, as they have no visible imperfections when viewed under 10X magnification.



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 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 e.g. 6.5mm diameter simulated diamond is the same size as a 1carat diamond.



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.



Your jewellery will be forever admired, therefore it is important that proper care is given to ensure your stones always sparkle at their best. Dust, lotions, soaps and daily wear can cloud the brilliance and dull the surface of your jewellery and stones. We recommend using the Secrets gold or silver jewellery cleaner - following the instructions as prescribed by the manufacturer.

Secrets also offers a complimentary cleaning service. Simply call in to the store of your choice at any time and we will professionally clean your jewellery for you.

Secrets Signature Diamond Simulants (and coloured stones) should be given the same level of protection and respect as a diamond, even a diamond will chip/break if hit with force. Gardening and heavy lifting can expose your jewellery to damage - avoid wearing your jewellery during these activities. Hard and abrasive surfaces can damage your Secrets jewellery. Please take care to avoid any surfaces that may damage your jewellery.

Time-worn claws or settings may result in the loss of a stone and therefore we suggest the following basic care to preserve and protect your Secrets jewellery. As all fine jewellery requires maintenance, Secrets recommends that once a year you bring your jewellery into your local Secrets store for an annual maintenance check, where our qualified jewellers will clean, polish and check your settings. We apply a small fee for this service.

Freshwater cultured pearls are very delicate and therefore should be treated with extra care. To clean, simply wipe them with a soft, dampened clean cloth, or use the Secrets recommended professional pearl cleaner. Your pearls can be damaged if exposed to rough surfaces, as well as chemicals such as laundry detergent and ammonia.

All white gold is made from natural yellow gold. It is then mixed with various metal alloys to create white gold, which, in its natural state has a greyish appearance. White gold jewellery is then rhodium plated to produce a beautiful lustrous finish. To ensure your jewellery always looks its best, it will need to be re-rhodium plated periodically. This is standard for all white gold jewellery. How often it will need to be re-rhodium plated will vary depending on the type of wear and your natural acidity levels. We apply a small fee for this service.

All Secrets silver jewellery is sterling silver which is the highest grade of silver - and we apply rhodium plating over each piece to give it a bright appearance and to stop the silver tarnishing.
Over time you can have this rhodium plating reapplied. We apply a small fee for this service.
