At Diamond Gallery, we prioritize the security and peace of mind of our valued customers. That’s why every loose diamond, diamond ring, and piece of jewellery purchased from us is accompanied by a comprehensive valuation report. This valuation report will assist you to get your jewellery properly insured.

Our insurance appraisal serves as a crucial document for insurance purposes, offering detailed insights into the approximate retail replacement value of the item. This value is meticulously calculated based on the current retail marketplace, providing you with an accurate representation of the worth of your jewellery. Additionally, the appraisal includes a thorough description and high-quality photograph of the item, capturing its unique characteristics and features. Furthermore, detailed information about the diamond, including carat weight, colour, and clarity, is provided, enhancing the appraisal’s comprehensive nature.

In the unfortunate event of loss, damage, and theft, our insurance appraisal plays a vital role in ensuring that you receive an equivalent replacement for the item from your insurance company. This invaluable document serves as evidence of the item’s value, facilitating a smooth and efficient claims process.

For those seeking an extra layer of protection and peace of mind beyond a standard home and contents policy, we recommend considering our partnership with Centrestone Insurance.

How To Measure

  1. Grab a tape measure, length of string or strip of paper.
  2. Wrap it around the finger you'll wear your ring on—if you’re creating a ring stack, consider where on your finger the ring will sit—and mark the place where it joins.
  3. Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart above to match the measurement to the closest ring size.
  1. Choose a ring that already fits your finger well.
  2. Measure the interior diameter of the ring in millimeters (mm).
  3. Use the measurement chart above to match the size of your ring to the closest size in mm.
