Navar Black Jewellery Valuation & Appraisal Services assesses all items utilising our exclusive ten-point appraisal system to provide a factual and informed market valuation of each jewellery item. Taking into account each individual item and the intended use of the assessment we ensure a true and knowledgeable valuation.(more on types of appraisals)
Our Appraisal System
Purpose of the Appraisal
We confirm all relevant details with the customer as to the appropriate nature of the appraisal. This is very important as the valuation details reflect the market use of the jewellery and the type of sale or replacement of the item.
Things to Take into Account:
i) The Precious Metal & Testing
Metals are tested using acid or electronic analysis to determine the caratage of the jewellery.
e.g. 24ct is 999.99 parts per 1000, 18ct is 750 parts per 1000.
ii) Identification of Gemstone/s
Gemstones are identified using a x10 loupe eyeglass or more complex techniques involving more advanced and specific gemmological instruments including binocular microscope and refractometer.
iii) Analyse the Quality of Stone/s
Grading of the gemstone is achieved through detailed analysis of its colour, cut and clarity.
Other Things to Consider
a) Antique/Period Jewellery
We are not able to apply the exact same methods of appraisal to an antique or period piece as we do with contemporary pieces. The craftsmanship and gemstone cutting must be judged by the prevalent standards of the time. (more on time)
iv) Analyse the Size of Stone/s
When gemstones are set in jewellery an estimated total weight is measured and calculated, while with loose stones it is possible to measure the positive weight of the stone.
v) Manufacturing Technique Identification
An assessment is completed into how the item was crafted (cast, die struck, handmade, etc. or a combination)
vi) Manner and Quality of Settings
There are many types of settings and components that can make up an item. Each type of setting is individually assessed for its quality and complexity, as this affects the total valuation of the item.
Three very important questions..........
i) Who was the craftsman?
ii) Where was it made?
iii) Who wore it?
These questions reflect on the intrinsic value of a period or antique piece. Proof that an item was made by a specific craftsman or wore by a person of note will always have a premium added to its value.
The Valuation/Appraisal Certificate
Each component of the piece (the mount, settings and gemstones) are all given a price. The combined components determine the estimated value based on the market value of the appropriate nature or purpose of the valuation. This is then documented with High Definition photographic evidence and a certificate is provided to the client.
