Secrets Shhh was co-founded in 2000 by award-winning jewellery designer Dietmar, and Jane. Together their combined 30 years’ jewellery experience unearthed the awareness that not all women could afford the diamond of their dreams.

This partnership has now grown into a team of dedicated designers, sales professionals and more, constantly working to provide every customer around the globe the opportunity to feel good about what they are wearing.


Secrets Shhh is the home of the diamond alternative. Our man-made white stones are what the jewellery industry calls diamond simulants. A simulation is a copy and we copy only the best. Using the latest technology in diamond simulants, our superior quality stones are made in laboratories from the natural mineral base zirconium oxide.

Our stones possess all the optical qualities of the finest quality diamonds unearthed. In fact, they are visibly whiter and brighter than most diamonds you’ll find mounted in your typical ‘middle market’ engagement ring. Even the naked eye cannot tell the difference between a Secrets diamond simulant and a mined diamond.

Our stones are cut to the same exact proportions and standards demanded by the diamond industry to ensure for maximum fire, brilliance and scintillation. Our customers frequently remark that our diamond simulants have more sparkle than the average mined diamond. This is because of the superior clarity of our stones, plus the fact they’re cut just like a diamond, which means they will sparkle – a lot! Secrets resonates with our customers because our jewellery is simply beautiful and does not cost the Earth. Our stones are proudly man-made and conflict-free. Their production has a lesser impact on the Earth plus they’re a fraction of the retail price of a mined diamond. We believe we offer the world a better beautiful.


Secrets Diamond Simulants are guaranteed to retain their beauty, colour and brilliance forever and this lifetime guarantee is our promise to you. Your stone will be replaced should it discolour or lose its brilliance under normal wear.  Should the ring be over 12 months old a nominal jewellers charge will apply.


Diamonds and Secrets Diamond Simulants are valued on four criteria: colour, clarity, carat and cut. Our stones are not a synthetic diamond grown from a carbon base.


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 grade internally flawless to VVS2


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 millimetres 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.  We offer stones up to 10 carats or more in equivalent diamond weight.


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 into 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.

White gold jewellery is 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. The same also applies for sterling silver jewellery.
