Our experts study the 7 factors that are an important determinant in Pearl Grading and Classification. The grading test or exposure to our equipment will not affect the smoothness, quality or the surface of the Pearl. We ensure the best quality and safety process in determining our grade tests.

• Size of the Pearl
• Shape of the Pearl
• Color of the Pearl
• Luster of the Pearl
• Surface Properties of the Pearl
  Nacre Quality of the Pearl

After analyzing these properties in detail, our grading experts detail out the origin of the pearl – natural or cultured or nucleation, mollusk type if it is possible to determine, birth environment – saltwater or freshwater, any possible treatments and detailed characteristics like quantity, weight, shape, etc.

Our high equipment and skilled grading experts can make it possible to even include luster, surface, nacre thickness, and matching (if applicable).
Any more specific queries or consultations, beyond the above scope will attract additional charges and another testing process.

Natural pearls are born in deep waters when a parasite enters the saltwater oyster, freshwater mussel and then the mollusk secretes a fluid, called a nacre, to coat the irritation. Then the layers of nacre grow over time to create a natural pearl.

Over a time now, discoveries in pearl culturing have revolutionized the market and replaced natural pearls creating confusion in minds of the buyer. To sort out this question, Geological Institute of India, has brought out for the very first time, an unique Geological Institute of India PEARL GRADING REPORT that grades the pearl in a comprehensive way like natural diamonds.

We accept the following types of pearls for analysis and classification depending upon the client requirement.

• Natural Pearls
• Cultured Pearls
• Beaded Pearls
• Pearls Lots
• Imitations Strings of Pearls
