For centuries, pearls have been one of the most popular and beloved gems in the world.

But then you may ask “What makes some pearls worth more than the others?” and “What is the value of my pearls?”

1. Luster: GIA (Gemological Institute of America) researched that luster, referring to the intensity of the reflected light throughout the surface and the clarity of the image is the most crucial factor.

    • Excellent – Reflections appear bright and sharp
    • Very Good – Reflections appear bright and near sharp
    • Good – Reflections are bright but not sharp, and slightly hazy around the edges
    • Fair – Reflections are weak and blurred
    • Poor – Reflections are dim and diffused

2. Shape: Pearls are mainly separated into four categories:

  • Round/Semi-Round
  • Drop
  • Baroque, and
  • Circle Baroque

The idea shape is perfectly round. However, irregular shape in some cases improves the uniqueness of the pearl collection.

3. Surface Quality:

Like colored stones, most pearls never achieved perfection. If the surface of the pearl is totally smooth and flawless, it is considered to be in the highest grade, while if discovered any cracks, scratches and inequality on the surface will reduce the value of the pearl.

  • Nucleus Visible, and

How to Care for Pearls

Pearls need fresh air, put them up every few months, let them expose to air and breath often to avoid them from turning yellow.

2. Prevent direct exposure to sun

Pearls contain a certain amount of water, so they should be kept in a cool place to avoid dehydration.

The pearls are advisable to be re-string every 3 years.

4. No contact with chemicals

 Avoid letting pearls contact with acids, alkaline and chemicals, such as soap, perfume, styling gel, etc.

5. Never kept close to the kitchen

There are tiny pores on the surface of the pearl. Thus, avoid wearing the pearl close to oily fume, otherwise it will turn yellow.
