Jewelry appraisal is the process of assessing the value of a piece of jewelry, typically for insurance, resale, or estate purposes. At HIDDENSPACE, a GIA (Gemological Institute of America) certified appraiser examines various aspects of your jewelry, such as its materials, craftsmanship, design, and market demand, to determine its worth.


We value your jewelry as much as you do. It is highly recommended to have your jewelry appraised by a professional jeweler for any pieces that hold significant sentimental or financial value. An appraisal not only provides an accurate valuation of the item's worth, but it also serves as an important document for insurance purposes, estate planning, and potential sale of the jewelry.

In the unfortunate event of loss, theft, or damage, an appraisal can save you from substantial financial loss. Without an appraisal, your insurance company may not cover the full value of the jewelry.

Moreover, an appraisal helps you plan for the future. It ensures that your assets are distributed fairly among heirs or beneficiaries, avoiding conflicts and disputes. 

A professional appraisal for your jewelry is a wise lifetime investment that can provide peace of mind, financial security, and fair distribution of assets. Don't risk losing or undervaluing your precious possessions! 


A digital mockup is a 3D rendering image, created by a jewelry software and photoshop. This will help you to understand general layouts of gemstones and the entire look of the design.


Your first two mockups are complimentary and may take up to three business days to complete. Please note that the gemstone you choose may sell during the rendering process. To prevent this issue, you are able to pre-order your gemstone and request a mockup afterward. 

We are pleased to offer digital mockups for serious inquiries.
Before submitting your request, please ensure the information provided below is accurate.
