An appraisal is an opinion of value based upon research of comparable objects within the most relevant market. As part of the appraisal process, an item is physically examined, measured, photographed, and researched.  An appraisal is fee-based and is a formal, written document.  Our appraisals are based upon the Uniform Standards of Professional Appraisal Practice (USPAP) as set forth by the Appraisal Standards Board of the Appraisal Foundation, and with the Principles of Appraisal Practices and Code of Ethics of the American Society of Appraisers in Washington, DC.

A gemologist is an expert in the field of gemstones, who has been trained to identify, evaluate, and appraise gemstones. Gemologists use a combination of scientific knowledge, specialized equipment, and visual examination to determine the quality, characteristics, and value of gemstones.

Having your jewelry appraised can be important for several reasons, including insurance purposes, estate planning, and selling or buying jewelry. An appraisal will provide you with an accurate and detailed description of your jewelry, including its quality, characteristics, and value, which can be useful for insurance coverage or in determining a fair price for buying or selling.

The value of a gemstone is determined by its quality, rarity, and demand. Gemologists evaluate a gemstone based on its cut, clarity, color, and carat weight, as well as other factors such as its origin and history. Demand for a particular gemstone can also impact its value.

A certified gemstone has been evaluated and graded by a recognized gemological laboratory, which provides an official report of the stone’s characteristics and quality. A non-certified gemstone has not undergone this official evaluation, which can make its quality and value more difficult to determine.

It is recommended that you have your jewelry appraised every three to five years, or if there have been any significant changes in its condition or value. It is also a good idea to have your jewelry appraised if you are considering selling or insuring it.

When choosing a gemologist, it is important to look for someone who is qualified and experienced in the field of gemology. Look for certifications or affiliations with recognized gemological organizations, as well as positive reviews and recommendations from past clients. It is also important to choose someone who is trustworthy and transparent in their appraisal process.
