With over two decades of experience in the diamond and jewellery industry, SACOTECH has perfected the art of auctioning diamond, placing it in a class of its own. Every step in the process – from the selection of the finest diamonds, to the design and creation process – each step is completed with meticulous attention to detail. The SACOTECH Quality Assurance covers the authenticity of the diamonds, gems and metals used as stated on your invoice and Certificate of Authenticity for life.


A diamond is as unique as you are. The combination of its cut, colour, clarity and carat weight make up a diamond’s unique fingerprint, with no two diamonds being the same. Sourced mainly from South African mines, a SACOTECH diamond is polished to realise its true potential and is graded by international diamond laboratories such as the Gemological Institute of America (GIA) or the European Gemological Laboratory (EGL); or the Scientific Grading Laboratory (SGL).

Most diamonds larger than 0.5 carats are laser inscribed with a unique diamond identification number in letters no larger than a few micron on its girdle. This identification number and the diamond’s unique characteristics are recorded on a Certificate of Authenticity, assuring your diamond matches the diamond certificate and authenticity report (for life). Should the characteristics of the diamond you purchased be different from the characteristics stated on your Certificate of Authenticity (or the diamond grading report), we will accept the return of your diamond and exchange it for another diamond of the same, or better, characteristics as stated on the certificate, free of charge.

If we cannot replace the diamond for you, we will refund the purchase price in full. This SACOTECH Lifetime Diamond Guarantee is yours forever. This guarantee is void if the item was handled or repaired by another company; or in the event of accidental damage that can affect the diamond.


At SACOTECH, only the certified diamonds are used in every SACOTECH creation. We take care to ensure the best workmanship so that each creation is crafted to the SACOTECH-standard. We therefore warrant all jewellery items will be free from any manufacturing defect at time of purchase, with platinum and gold content guaranteed for life. We want you to enjoy your SACOTECH jewellery creation for many years to come, and like other luxury products on the market, diamonds and jewellery require care and maintenance to keep them looking their best.

As part of the SACOTECH Lifetime Jewellery Warranty, you are required to have your diamond jewellery inspected at any SACOTECH store every 6 months from the date of purchase, in order to maintain the validity of this warranty. During the inspection your jewellery item will be examined free of charge, including any service or repair work that may be required at our recommendation. Any work due to manufacturing fault will be carried out free of charge. This excludes any fair wear or accidental damage. This warranty is void if another party conducts any work on your SACOTECH piece.
