A Heritage of excellence


There are many factors to consider when selecting an auction company. It is important to make yourself aware of an Auction Company’s expertise and history in selling items similar to your own. For example, you would not consign fine antiques to an Auction Company whose specialty is farm equipment or commercial machinery. Nor would you wish to consign fine jewelry-Diamonds to a company without any expertise in that field.

Fair market values can be a challenge


Fair market value can be defined as the price at which a willing purchaser will pay a willing seller, neither being under any obligation and both having reasonable knowledge of all the relevant facts, within a common marketplace such as an auction, at a certain period in time.

Fair market values differ significantly from retail replacement values that are usually done for insurance purposes. These appraisals reflect the hypothetical price a retailer might charge to custom-make or duplicate an item during a period of time. Often these appraisals are well above jewellers current stock prices.

The first step in the auction process is to obtain an estimate of what an item might bring at auction, or its fair market value. This information is provided within the context of an initial consultation with one of our specialists.
