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.
Your peace of mind is our priority. Every order is fully insured and meticulously packed in a protective jewelry presentation box. We guarantee a full refund or replacement should any damage or loss occur during delivery.

配送について
ただ、配送方法に関しては少し不便でした。宅配便ではなく、ゆうパケットで届いたため、郵便局で荷物を受け取る必要がありました。これは私にとって便利ではありませんでした。EMSの利用をお勧めします。
I bought it as a birthday gift for the girl i love.She said she thought it was beautiful and delicate.
I fell in love at first sight, so I was worried that a size 13 wouldn't fit, but I'm glad it did. It's cute just by itself, but it also looks great layered with a thin colored stone ring! I'm looking forward to wearing it in various ways! Thank you so much.
I want to give it 10 stars!
I've been wanting this for a long time. I finally got it. It's so beautiful. My first reaction when it arrived was, "Wow!"
It even came with a certificate of authenticity from the Pearl Chemical Laboratory. I'm so happy that they sent me such fine pearls. They're so beautiful, I can't help but be captivated.
I purchased the necklace and earring set at your physical store in Ginza and wasn't worried about the store, but I'm impressed that they really do specialize in pearls.
It's a formal occasion, so I don't often get to wear it, but the beauty of Akoya pearls is truly exceptional. I splurged on the ring, too, because I wanted an Aurora HANADAMA Akoya pearls!
Even though I purchased it online, it was so beautiful, I'm so happy that it came to me.
I've been admiring pearl necklaces from Pearl Keeper for a while now, but adding this ring will make me even more enchanted. Thank you.
Highly impressed. The piece is beautiful. It adds an air of grace to simple outfits , very stylish and fashionable. I will continue to order from your shop.
I chose yellow gold.
It's a single pearl, but it has a strong presence.
The luster and size of the pearl, as well as the ability to adjust the chain length, were all great.
I bought this as a birthday gift for my daughter. It's so cute and she loved it.
I really like it because it suits short hair.
I bought this as a wedding gift and am very happy with it.
I gave these as a gift to my second son's wife.
I had the earrings' metal fittings changed to 14WG.
The pearls were beautiful and I was glad she was pleased with them.
