Providing an accurate valuation involves science, education, and an understanding of the market.
THE VALUATION METHOD
Over the years we have developed a precise formula to calculate the true and fair market value of an item. The formula used by Brisbane Jewellery Valuers is outlined below.
WHAT IS THE VALUATION NEED FOR?
The client is to provide the market in which they would like their item to be replaced;
• Retail replacement -(commonly used for insurance purposes)
• Estate division - generally directed by solicitors
• Private sale
• Technical information
If a retail replacement is required a place of replacement is needs also to be determined i.e; at a traditional jewellery store, a large commercial jeweller chain store, a high end jewellery store etc
IDENTIFYING THE METAL & WEIGHING THE ITEM
The item is tested with acid to verify the approximate gold content i.e 18ct, 14ct, 9ct. The item is weighed on a calibrated scale and the weight is expressed in grams.
IDENTIFYING THE METHOD OF MANUFACTURE
The method in which the item was manufactured; i.e handmade, cast, or a combination of both. The manufacture includes the manner in which the gems are set; ie cast in place, individually grain set, channel set ect The value of a piece of jewellery can vary dramatically according to the method of manufacture, and the complexity and quality of manufacture.
ASSESSING THE GEMSTONES
Using a 10x hand lens and specialised scientific gemmological equipment we are able to identify the gem/s and assess the quality. Measurements of the gems are taken, and approximate gem weights are calculated.
ARRIVING AT A VALUE
After assessing the manufacture, the caratage of the metal, and the type, quality and size of the gems, these elements are combined and a value is determined in the appropriate market/s. A valuation certificate is produced stating all the relevant information i.e description of the item, weight, carat, gems and their quality, a picture of the item, and of course, the relevant value.
