The 6 cultured pearls quality factors

Yves Lemay | Aug 10, 20

There are 6 main factors to keep in mind when determining a pearl's quality and worth: Nacre, Luster, Surface, Shape, Color, and Size. When it comes to quality pearls, like most things, size does matter. A critical factor in a pearl's value is its size, with the larger pearls generally being the more prized.

How pearls are made

Pearls are unique among gemstones, being the only ones found within a living creature and the only ones that require no fashioning before use. Another distinctive feature is its near-exclusive use by one gender. Although some efforts have been made to market pearl jewelry to males in recent years, pearls remain the most "feminine" of all gemstones. Designated officially as the June Birthstone, it is, unofficially, a near requirement for brides.

What is beryl

Whether blue, green, yellow, colorless, or pink, their chemical and physical properties essentially correspond; only in their colors they differ from one another so much.As pure beryl, they are colorless, but they can account for their structure to store various foreign substances, which gives rise to the numerous colors, turning a plain, colorless gemstone into a green, yellow, pink, or blue treasure.

What are geodes

Geodes are technically sedimentary rocks since they are the result of the action of water. Geodes are formed when cavities in a host rock (which may be sedimentary or igneous) become lined with a durable mineral, often a variety of quartz.

How gemstones get their colors

Color in minerals is caused by the absorption or lack of absorption of various wavelengths of light. When pure white light, containing all wavelengths of visible light, enters a crystal, some of the wavelengths might be absorbed while other wavelengths may be emitted. If this happens, then the light that leaves the crystal will no longer be white but will have some color.

Mohs scale of hardness

Hardness is one measure of the strength of the mineral's structure relative to the strength of its chemical bonds. It is not the same as brittleness, which is another measure of strength, purely related to the structure of the mineral. Minerals with small atoms, packed tightly together with strong covalent bonds throughout tend to be the hardest minerals.
