Our STONEs
The Sustainable Lab-Grown Alternative to Mined Diamonds



We are experts in sustainable alternatives to mined diamonds. For over two decades we have specialised exclusively in lab-grown alternatives to mined diamonds, carefully perfecting our Signature Simulant Diamonds.
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 Simulant Diamonds 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.

Our Simulant Diamonds do not share the same chemical properties as mined or synthetic diamonds, rather they are responsibly grown using the latest technology, under extreme heat from the mineral base zirconium oxide, to form the highest grade AAAAA cubic zirconia. They are a genuine, lasting, high quality, alternative to diamonds mined from the earth.
