Gemologist / Advantages
Gemology is the science and study of natural and artificial gemstones; their sources, descriptions, origins, identification, grading and appraising. It is considered a geoscience and a branch of mineralogy.

Appraisals are extremely important for anyone who owns a special piece of jewelry. For several reasons, these jewels should be valued and certified by an expert to avoid difficult situations and even loss in certain cases.

In case of inheritance, loss, theft, buying, selling, insuring and or division of capital gain, a professional appraisal will be your most useful tool in any decision making process.

One common example of a difficult situation with an insurance company comes at the time of a claim.
There have been cases where such claim is delayed due to incomplete, inadequate paperwork or appraisal documentation, doubts and irregularities of presented documents for the insured items.

A good appraisal will help make the process clear, fair and quick.

In another situation where a sale is taking place, both sides should count on a professional certificate of authenticity and adequate appraisal documentation with values to satisfy both parties and make an honest and fair transaction.
  • Verify the descriptions of the jewels to make sure they are detailed and precise.
  • Ask to have photographs of your jewelry included if possible.
  • Assure yourself of using a Professional and Certified Gemologist with knowledge of costs and values in the actual markets.
