Pearl Knowledge and Guide

pearl The English name is Pearl, which evolved from the Latin word Pernul o. Natural and magnificent pearls grow in seawater or freshwater waters. Pearls are collected mainly through natural excavation and artificial cultivation. When a clam with a nacreous layer in the sea opens its shell to breathe, and sand or microorganisms in the sea enter the clam's body, the clam is stimulated and feels uncomfortable, and it secretes nacre to surround the intruder in layers to relieve pain. After years of secretion, the invader forms a pearl. Due to the long growth time of natural pearls, the texture of natural pearls after they become beads is fine, the bead layer is thick, the skin is smooth, there are few "bubbles", and they are relatively transparent. However, pure natural pearls are very rare in nature, and most of the pearls on the market today are produced through artificial cultivation. Professional cultivators need to implant a small bead into the mother-of-pearl, and over time, multiple layers of natural minerals and proteins will cover the bead. It is the nacre that gives the pearl its beautiful luster and color.

5 Criteria for Determining the Value of Pearls

Since the establishment of WILLS, each pearl has undergone strict supervision and the highest quality products have been carefully selected to offer to consumers. We use the following five main factors to determine the grade of each pearl as a standard:

1. Color

The luster of freshwater pearls is relatively soft, and the colors include white, pink, purple, etc. White is the most produced, and some merchants will dye the pearls based on market demand. Akoya pearls have the strongest luster and iridescence among all pearls, and are mainly available in pink, blue-green and silver. Among them, the white and rosy pink is the most popular in the market. In terms of South Sea pearls, there are mainly white, black, silver and gold, among which gold is the most expensive. Tahitian black pearls are particularly rich in color. Its black base can be transformed into malachite green, black, rich purple, ocean blue and other colors. Among them, malachite green is the top grade among black pearls. The stronger and thicker the iridescence, the higher the value.


Luster refers to the light entering the special internal structure of the pearl, and the light reflected by the nacre layer presents a brilliance effect, also known as skin luster. The crystal clear and soft luster of pearls will vary depending on the internal structure of the pearl, such as the thickness, uniformity, and transparency of the nacre layer. It is one of the important factors that determine the quality of pearls.

Healthy mother oysters will give pearls beautiful luster, so when looking for pearls of different qualities, you can observe the difference in luster. The luster depends on the reflectivity of light on the pearl skin. The higher the reflectivity, the brighter the pearl. good.

(AAAA is the highest quality)

Pearls with excellent skin luster will produce a mirror-like reflection effect under the refraction of light, so it is indispensable to choose good quality pearl luster.

WILLS JEWELLERY has strict requirements for pearls and will only use pearls with high-quality luster and luster, in order to enable customers to buy their favorite pearls with higher cost-effectiveness.


Because natural pearls are nature's most precious gifts and cannot be subjected to excessive polishing, the production of natural pearls that are closer to a perfect round shape is rare. Shapes that are not spherical or even asymmetrical are considered lower quality and are also called deformed beads. In recent years, a number of foreign customers have become interested in deformed beads, such as teardrop shapes, which are highly valued due to the scarcity of production quantities.

4. Surface defects

The fewer flaws a pearl has, the higher its value will naturally be. Pearls are grown from molluscs, and the covering of nacre doesn't necessarily stick together smoothly. The type and specificity of imperfections vary widely, and blemishes such as blemishes , bubbles , bumps or spots may appear during the layering process . Defects are classified into natural or acquired. WILLS will analyze the cause, location and distribution of the pearl's flaws for customers to make a score.

5. Size

The size of the pearl also plays a decisive role in the value of the pearl. When the quality is the same, the bigger it is, the more valuable it is. Pearls are generally classified in grades of 0.5 mm, such as 6 to 6.5 mm and 6.5 to 7 mm. If it is a pearl necklace of different sizes, it will be defined according to the range of the largest and smallest pearls. For example, if the maximum size of a string of pearls is 10 mm and the minimum size is 8 mm, then the size of the string of pearls will be 8-10 mm. Different types of pearls also come in different sizes:

  • South Sea Pearl: The largest pearl in size, with a diameter of 10 to 18 mm
  • Akoya Japanese pearls: generally only 2 to 9 mm
  • Freshwater pearls: The widest range of layers, ranging from 4 to 17 mm
  • Tahitian black pearls: generally between 8 and 10 mm in size


If pearls are cared for properly, they can last for a long time. The best way to care for pearls is to wear them regularly, as the body's natural oils can maintain their luster. Since pearls are organic gemstones with high water content, they are easily corroded by acids, alkalis or other chemical substances, causing their luster to dim. Therefore, pearls need to be kept away from household chemicals, including perfumes, cosmetics and hair sprays. It is recommended that you put your pearls on at the last moment before getting ready to go out, and take them off first when you get home. Before replacing your pearls, wipe them with a soft cloth and store them away from other jewelry to avoid scratching their fragile surface.

Choosing pearls is different from diamonds. There is no 4C guideline, so every little fan can choose different pearls according to your favorite color, size, shape, price, etc. I hope WILLS and the editor can bring more differences to you little fans. A new pearl experience!
