They have different characteristics and chemical compositions. However, each option has distinct advantages over the other. We offer our Secrets Signature Simulant Diamonds and (from 2023) a curated collection of Premium Certified Laboratory Created Diamonds.

The difference is the chemical composition of the stones. Secrets Signature Simulant Diamonds are grown in a lab from the mineral base zirconium oxide and are the highest grade latest technology AAAAA cubic zirconia. Moissanite is also a simulant diamond grown in a lab from silicon carbide. Laboratory created diamonds are grown from a lab-grown carbon seed and are chemically identical to a mined diamond. All three stones are created in a lab with minmal environmental impact.

Our Premium Certified Laboratory Created diamonds are grown in a laboratory from a lab-grown carbon seed, under extreme heat and pressure to recreate the conditions under the earth's surface. There are two main methods of growing the diamonds, being HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Disposition). Both methods are capable of producing beautiful diamonds of the highest grades and qualities.

At Secrets Shhh, our Signature Simulant Diamonds and our Premium Certified Laboratory Created Diamonds are graded as minimum Colour F, minimum Clarity VS2, Excellent Cut, Symmetry and Proportions.

Yes, they are both the same hardness being 10 on the Mohs Scale of Hardness.

Yes – there is no difference between man made lab grown diamonds and mined diamonds; the same methods are used to test both. Both stones are chemically, physically, and optically identical, so they will exhibit the same properties and characteristics when tested. Among these are hardness, refractive index, thermal conductivity, and other unique characteristics of diamonds, whether they are mined or lab grown diamonds.

Our Signature Simulant Diamonds are grown in a lab from the mineral base zirconium oxide. Colour D to F and clarity IF to VS, they are cut to the highest standards for maximum fire and brilliance. They are the highest grade, latest technology AAAAA cubic zirconia and come with a lifetime guarantee for internal fire, brilliance, and loss. Eco-friendly and conflict free, they are a more responsible and beautiful choice.

Our Signature Simulant Diamonds are rated 8.5 on the Mohs scale of hardness which is similar to sapphire and harder than many mined gemstones. All gemstones including diamonds should be worn with care, avoiding abrasive surfaces and unusual wear and tear. Our Signature Simulant Diamonds come with a lifetime guarantee for internal fire, brilliance, and loss. However, if your ring is accidentally damaged, there may be a charge to repair the piece.

Our Signature Simulant Diamonds are graded as minimum colour F, minimum clarity VS2, with excellent cut, symmetry, and proportions. They are the equivalent grades to the finest mined diamonds.

Both are referred to as simulant diamonds or diamond simulants. Each stone has its advantage, with Moissanite being slightly harder, and Secrets Shhh Signature Simulant Diamonds being more beautiful optically with more natural light performance and scintillation.

Our Circularity Guarantee allows you to refresh your jewellery wardrobe with new and exciting pieces. In certain circumstances it also allows you the opportunity to trade back your Signature Simulant Diamond for an equivalent piece in a Premium Laboratory Created Diamond.
