What is the Free Home Trial service?

We want to help you choose jewellery that you absolutely love. It’s so important to try a piece of jewellery before you decide to own it forever. Before you make your decision, we want you to be completely sure. So, our Free Home Trial service allows you to try on three designs in the comfort of your own home for five days. We encourage you to wear them, flaunt them, get opinions from friends and family before deciding the one (or more!) that you would like to be custom made.

Can I use the Free Home Trial service if I live outside the UK?

The Free Home Trial service is currently available to UK customers only.

Can I buy the Free Home Trial products?

These are just samples and are not available for sale. We know they look quite real, but they're not the real thing!

Is the Free Home Trial free?

Your Free Home Trial is absolutely free (including shipping and returns). However, for security purposes, we require a security deposit just in case we do not receive your Free Home Trial samples within the agreed time frame or if they are returned damaged. We will charge £99 per sample, which will be totally refunded when we receive the samples back.

When do I have to return my Free Home Trial samples?

Please return the samples using the free return shipping label provided within five days following receipt to avoid any charges. If your Free Home Trial period ends on a weekend or holiday, just post it on the next available working day. If you need an additional day or so, just email us at [email protected] to let us know.

How many Free Home Trial products can I select?

You can select up to three designs to try out.

Can I select the same products in different colours?

Currently we provide all samples only in White Gold colour.

I can’t find the product for my specific size?

At the moment, we have only a few standard sizes for Free Home Trial. We will constantly add more sizes in the future.

Can I order multiple Free Home Trials?

You can only order one free Home Trial at a time. You can order another one after all samples from an existing Free Home Trial are returned.

Do you clean the Free Home Trial samples once they’ve been returned?

Yes. We use an ultrasonic cleaning technique (described below) to professionally clean all of our Free Home Trial samples before sending them out.

Whilst we are confident that all of our Free Home Trial samples are professionally cleaned and safe to re-use, use of these items is at your personal discretion and risk.

What about pierced jewellery?

We include pierced jewellery in our Free Home Trial service and whilst we professionally clean all Free Home Trial jewellery before sending them out we advise you not to wear the pierced jewellery samples.

What is ultrasonic cleaning?

We use an Ultrasonic Cleaner which is a professional device which penetrates the high frequency ultrasound energy deep into cracks, holes, recesses to professionally clean and remove all traces of tightly fit germs and greasy substances.

Whilst we are confident as to the high hygienic standards of our Free Home Trial samples, use is at the customers own risk and we advise customers NOT to wear pierced jewellery samples.

Please refer to our Sacet Terms of Use www.sacet.com/terms-of-use for further information.

How do I find my ring size?

To find your ring size (or someone else's) head to our ring size guide for top tips and to request a free ring sizer.

Can I get my ring resized?

Yes, you can get your ring resized depending on the complexity of the design. We offer a 60-day free ring resizing service which includes ring resizing up to two sizes up or down for free. If your ring needs resizing or replacing any more than two sizes we charge £59/€59. Please bear in mind that any item returned for resizing must still be unworn, with the tag on and in pristine condition. This service includes engagement rings and wedding bands but currently excludes full eternity rings due to the complexity of the design. If you require further advice, please contact a member of our customer care team.

What are lab-created diamonds?

Lab-created diamonds or cultured diamonds are grown in highly controlled laboratory conditions using ground breaking technological processes that emulate the Earth’s natural developing process where diamonds form in the mantle of the Earth. The resulting diamonds are physically and chemically identical to mined diamonds since lab-created diamonds are made of the same material; pure carbon, crystallised in isotropic 3D form.

Lab-created diamonds aren’t new, in fact people have been experimenting with them for centuries, but the recent technologies advancements have helped us perfect the resulting diamonds. Nowadays, the resulting diamonds are just like the earth-mined ones but better since they are made in a fairest and ethical way, decreasing the conflict among the communities.

Our lab-created diamonds are 100% conflict-free and superior quality than earth-mined diamonds.

How are lab-created diamonds grown?

Lab-created diamonds are grown from a tiny carbon seed placed into a chamber of heat and pressure that mimics the natural method of diamond formation. Once the diamond has matured (approximately six to ten weeks), it is then cut and polish. Certified and renowned labs - that also verify earth-mined diamonds - will grade the lab-created diamonds.

At Sacet we grow our diamonds with an advanced technological process called Chemical Vapor Deposition or CVD, a method by which diamonds can be grown from a hydrocarbon gas.

This process uses ultra-pure carbon-rich gasses in a controlled chamber. These gases, a mixture of methane and hydrogen with a ratio of 1:99, are then ionised into chemically active radicals inside the growth chamber. These atoms will then fall onto a diamond substrate and build up layers, getting, as a result, a rough diamond. This process usually takes between six and ten weeks.

There are different versions of CVD, some of them are:

  • Ultrahigh vacuum CVD (UHVCVD)
  • Low-pressure CVD (LPCVD)
  • Microwave Plasma Vapor Deposition (MPCVD)
  • Plasma-enhanced chemical vapour deposition (PECVD)

Why should you choose a Sacet lab-created diamond?

We work together with the best and most technically advanced diamond labs who share our core values: People. Planet. Profit.

We aim to transform the jewellery industry and by choosing to create stunning jewellery with ethical, conflict-free lab-created diamonds we are already ahead of the game.

At Sacet, we offer the best, ethically sourced, lab-created diamonds available.


  • Eco-Friendly: Lab-created diamonds are grown without negatively affecting native communities or the Earth. The use of water and the amount of land disturbed is also significantly lower during the creation of a lab-created diamond. For example, 18.5 litres are used to create a 1-carat against the 126 gallons of water used for every 1-carat Earth-mined diamond.
  • Quality: Cultured diamonds have the same physical, chemical and optical properties as Earth-mined diamonds. Our lab-created diamonds are Type IIa, the purest form of diamond. This type is harder and more brilliant and only 2% of Earth-mined diamonds are of this quality.
  • Value: another benefit of lab-created diamonds is that they cost up to 30% - 40% less than Earth-mined diamonds.

Do lab-created diamonds come with a certificate?

Yes, they do. At SACET you can choose between an SGL certificate and our exclusive certificates done by a skilled and trained gemmologist.

What is the difference between a diamond certificate and a valuation certificate?

A valuation certificate will establish the value of the item, mainly for insurance purposes. On the contrary, a diamond certificate will evaluate the specifications and characteristics of the diamond.
