Authentic grading based on 30 years of wholesale experience.
Learn correctly the three pillars that determine pearl value: luster, nacre, and blemishes.
Unlike diamonds, pearls have no universal grading system. To make your choice easier, WSP developed a strict five-level grading scale (Grades A–E).
We carefully evaluate the balance of luster, nacre, and surface condition.
Online, we offer only Grades A (Excellent) through C (Standard).
Pearls that fall below this standard are not part of our collection.
Truly beautiful pearls are defined by a high level of balance across all three elements.
1. Luster
The strength of shine, often called the life of a pearl. Strong luster reflects surroundings like a mirror and gives depth. It is the most eye-catching element.
2. Nacre
The thickness of the pearl layer. Thick nacre improves durability, prevents aging, and creates complex colors through light interference (aurora effect).
3. Blemishes
Surface smoothness. Pearls naturally have tiny imperfections called dimples, but we select pearls with smoother surfaces that do not detract from their appearance.
Because pearls are gemstones created by nature, no two are exactly alike.
We introduce their diverse shapes and the sizes that change their impression.
Pearl shapes are clearly defined into specific categories such as round, semi-round (almost round), semi-baroque (slightly irregular), and baroque (irregular). Other shapes include drop (teardrop), button (slightly flat), and oval (elongated).
We suggest starting with our "Grade B (Fine Quality)" or higher. This grade strikes the perfect balance of durability and brilliance, making it versatile enough for both casual and formal settings. For an heirloom piece designed to last a lifetime, our "Grade A (Excellent)" is the ideal choice.
Nacre is the heart of a pearl's longevity. A thick nacre layer protects against aging and allows the pearl to remain beautiful for generations. This depth also produces Luster the radiant luster unique to high-quality pearls. WSP places the utmost importance on harmonizing these two essential elements.

I would like to share my recent shopping experience, which was very positive. I purchased a necklace as a birthday gift for my wife, and I am very satisfied with both the product and service.After placing the order, I realized that I had provided an incorrect delivery address. I contacted your team immediately, and I truly appreciate the prompt and efficient response in resolving the issue.
In addition, I was pleasantly surprised by the delivery speed. The item arrived in Hong Kong within just three days, which exceeded my expectation.
Overall, it was a smooth and enjoyable shopping experience.
The earring is cute, delivery is fast
Pairs well with its outside pearl counterpart. Must say the product photography did a good job presenting the actual item.
Gorgeous. Pairs well with its inside pearl counterpart
Love it. Baby pearls are perfect for layering with other necklaces and doesnt look too much like granny’s pearls.
The pearl is securely fixed in the box. The cardboard is very sturdy, and the composed gray tone gives it a high-end feel.
Love the design and perfect for daily wear
Perfect size for everyday wear. Excellent quality
Very high quality pearl, gorgeous pink white hue!
