The Genuine Lab-Grown Alternative to Mined Diamonds

Secrets Shhh is the home of the diamond alternative. For two decades we have carefully perfected our Signature Diamond Simulants.

Proudly grown not mined, they are virtually indistinguishable to the naked eye when compared with the rarest white diamonds.

Only the pinnacle of stones grown, those with exceptional characteristics, are chosen for each Secrets Shhh design.

Our Diamond Simulants possess the very finest grades of colour and clarity, and are cut to the most exacting proportions demanded by the diamond industry. This ensures they display maximum levels of fire, brilliance and sparkle.

Our customers frequently comment how much they love their Secrets designs, and that they have more life and sparkle than their own mined diamonds. This is because they do sparkle a lot! Their light dispersion is superior at 0.058 – 0.066 exceeding a diamonds 0.044 rating.

Diamond Terminology

Diamonds are usually graded on the 4C’s of the GIA scale for colour, clarity, carat weight and cut, to determine their rarity and desirability. Secrets Diamond Simulants are graded on the same scale as mined diamonds. Our stones are grown for perfection in strictly controlled laboratory conditions to ensure your new Diamond Simulant’s grade is within the rarest grades being D-F colour, and near flawless clarity. They are also cut to ensure the highest levels of fire, brilliance and scintillation. Most display hearts and arrows. Each is explained below in more detail.

Diamond Simulants are a genuine lab-grown alternative to mined diamonds and do not share the same chemical structure, nor are they synthetic diamonds made from a carbon base.

Colour

Colour is graded alphabetically from D to Z, with D being the absolute finest colourless stone rating in the world. Discerning the difference between each grade of colour is extremely difficult, and requires a qualified gemmologist with specialist equipment. Secrets Diamond Simulants are graded D to E colour when compared on the GIA colour scale.

CLARITY

Clarity is determined by the levels of imperfection in a stone. Almost all diamonds and Diamond Simulants 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 qualified gemmologist and diamond grader. Secrets Diamond Simulants are graded Internally Flawless to VVS2.

Carat Weight

The weight of a diamond is expressed in carats. The word carat originates from the seeds of the carob tree, which were well known for their uniformity and consistent weight. Historically, diamonds and gemstones were weighed against these seeds. Today one carat is defined as one-fifth of a gram or 200 milligrams and the term carat remains the measure of weight. Two similar mined diamonds that have identical carat weights may actually appear very different depending on how they have been cut. For example a one carat mined diamond could actually appear much smaller than the next. This is because they are cut to save weight and to yield more from the rough stone. Our diamond simulants are cut consistently for perfection, not to save weight.

Secrets Shhh Diamond Simulants have a higher specific gravity than mined diamonds, which means they actually weigh more. Therefore we express their weight as a “carat equivalent weight” which is calculated by measurement. 

Cut

A well-proportioned and well cut diamond optimizes refracted light which creates its internal fire and brilliance. 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. These proportions are often varied by diamond cutters to yield more weight from the rough they are cutting, resulting in less fire and brilliance.

Secrets Diamond Simulants are cut using the most precise and exacting standards demanded by the diamond industry to ensure maximum fire and brilliance. Many of our round brilliant cut stones display a hearts and arrows pattern.
