The Holy Grail of Pearls: The Rare 6.5-7mm Aurora Tennyo Akoya Strand
In the world of pearl wholesaling, there’s a fine line between playing it safe and chasing perfection. Most of my colleagues in the industry thought I was a bit crazy to bring in a 6.5-7mm Aurora Tennyo (オーロラ天女) strand. They told me, “In this market, even mid-grade pearls in that size are a tough sell. Why take the risk?”
Maybe it’s my “perfectionist streak,” but I can’t help myself. There is nothing that compares to the joy of seeing a client’s eyes light up when they handle a truly world-class gem. Even if this strand stays in my collection for a while, I believe pieces of this caliber deserve to be showcased.





Why 6.5-7mm is the “Sweet Spot” for Daily Luxury
While 7-7.5mm is often considered the standard, the 6.5-7mm size offers a unique versatility that is often overlooked.
- For the Modern Woman in her 30s: This size radiates feminine grace and high-end luxury without feeling “too much.” It’s a favorite for bridal jewelry and special milestones.
- For the Sophisticated Professional in her 40s+: It serves as the ultimate “casual luxury” piece—perfect for elevating your daily wardrobe with effortless elegance.
- The Fit: The strand is a classic 41cm, extending to approximately 43cm once finished with our signature silver clasp.

The Gold Standard: Aurora Tennyo
The “Aurora Tennyo” title is the highest honor bestowed by the Pearl Science Laboratory in Japan. It is reserved exclusively for the top 10% of pearls that have already achieved the prestigious “Hanadama” grade.


- The Glow: This strand features a crisp white body color with mesmerizing pink and green overtones.
- Superior Luster: Forget AAA or “Excellent” ratings—this is a level of brilliance that stands in a league of its own.
- The Color Science: While many Akoya pearls lean heavily into pink, we’ve selected a “White + Pink” balance. Why? Because excessive pink can sometimes hide dark green undertones that dull the pearl’s radiance. This Tennyo strand, however, maintains a bright, vibrant glow that flatters any skin tone.
- Clarity: Out of the 61 pearls in this 41cm strand, a small fraction (about 10%) may have microscopic natural blemishes. However, at the Tennyo level, the luster is so intense that these tiny “birthmarks” are virtually invisible to the naked eye.
