The Full Diamond Report is a comprehensive report suitable for loose (unmounted) diamonds providing detailed information and expert opinion on all aspectsof the stone. Coloured diamonds will also be certified in this format after testing and identification. Details included on The Full Report are weight, measurements, colour, clarity, symmetry, polish, fluorescence, girdle description, shape and cut grade for round brilliants. The report also outlines details of the facet angles and proportions of the diamond. All Inclusions are plotted on the facet diagram thus uniquely identifying the stone. The Full Report provides where appropriate the proportion table for fancy cuts.
Full Report A5 without facet diagram
The short Report is only available for loose stones. The Short Report contains all the information and opinion provided in the Full Report, minus the detailed facet diagram. It has been developed as a midpoint between the Full Report and Mini Report. Both full and Short Report include the UKAS accreditation logo and also carry the unique anchor hologram to prevent forgery and copying.

Stones submitted to AnchorCert as laboratory grown diamonds can be certified verbally or on an A5 report. This includes the quality information as shown on a Full Diamond report, weight, shape, cut, colour, clarity, measurements, symmetry, polish, fluorescence, girdle and additional comments. The report also contains a digital image of the stone, the colour scale and measurements diagram
The Diamond Mini Report
The Mini Report is a highly popular and competitively priced report. It presents the diamond characteristics in a simple format and includes a digital image of the stone or piece of jewellery. A Mini Report is suitable for both loose, mounted and multi-set diamond jewellery. Important quality information included on the report are weight, shape, measurements, colour and clarity. This report is also UKAS accredited.
The Mini Report – Tanzanite
Beautiful and rare, Tanzanite is an increasingly popular gemstone. AnchorCert has developed a unique grading system and the report provides reassurance about the authenticity and quality of each stone submitted. This report can be carried out for loose, mounted and multi-set tanzanite jewellery. The Mini Report provides weight, shape, measurements, colour and clarity as well as a digital image of the stone or jewellery piece.
AnchorCert offers expert services covering every type of coloured gem. The detail provided on a Gemstone Report depends on the customer requirements and the stone. Basic identification is available on all cut stones and can sometimes be carried out on mounted stones. Testing and identifying treatments is a service in high demand and is available on all gems where as country of origin is only possible for some gemstones. Testing for treatments and origin require the stone to be loose. Results are provided by either written AnchorCert reports or verbal consultations.
Diamond Laser Inscription
An additional service available from AnchorCert is the laser inscription of diamonds. Using highly sophisticated laser equipment special messages or unique identification numbers (such as report number) can be inscribed on the girdle without harming the diamond in any way. Inscriptions can be applied to both loose stones and to diamonds that are already set into jewellery as long as the area to be inscribed is easily accessible.
