Appraisals & Insurance:
The following items purchased from our store include a free written insurance appraisal:
• Diamond engagement rings and wedding bands
• Diamond, gemstone, watch and pearl jewelry purchased for $1,000 and more.
An appraisal is a document stating the approximate retail replacement value of an item. It is calculated using current market data, which reflects typical retail prices. In addition to the cut, color, clarity, and carat weight of the gemstone(s), it includes the weight of precious metal included in the item, and the craftsmanship of the item.
Your insurance agency can rely on this appraisal to calculate a coverage rate for your diamond or piece of fine jewelry. Your appraisal ensures that in the case of loss, theft, or damage your insurance company will provide you with equal replacement value for your item. The more information contained in your appraisal, the more likely you are to receive the exact replacement value for that item.
