The mission of GINZA DIAMOND SHIRAISHI is to bring two people in love together with their destined diamond.

Consultant
A consultant is responsible for introducing and selling our wedding rings in-store.
Because we deal in “once-in-a-lifetime jewellery,” this role requires not only a high level of expertise, but also the ability to make proposals tailored to each customer’s lifestyle and needs.
Since 1999, Mr. Daisuke Hara has served as a trusted consultant, highly respected within and outside the company,
sharing his mission and the joy of working at the counter.

Shining as an industry-leading “wedding specialist,” while continuing to uphold the essence of service.
What kind of training is required before becoming a consultant at the counter?
After joining the company, I received long-term training shortly after—from basic hospitality etiquette to specialized knowledge of diamonds and platinum materials. All instructors were in-house experts.
As Japan’s oldest wedding jewellery specialty store, GINZA DIAMOND SHIRAISHI gains absolute confidence and pride from the strong feedback received at its boutiques.
On a personal level, as a wedding specialist, I obtained the BIA wedding coordinator qualification in 2010 to further ensure customers feel at ease.

What is the most important thing as a GINZA DIAMOND SHIRAISHI consultant?
At GINZA DIAMOND SHIRAISHI, everything is guided by “essence.”
Wedding rings and diamonds carry deep stories of love and time, which form their true beauty. Beyond brilliance, the brand aims to create rings meant to be cherished for a lifetime.
As wedding specialists, they also provide full wedding consultation—from rings to venue guidance—delivering service that stays true to its essence.
Through GINZA DIAMOND SHIRAISHI’s masterpiece “Saint Glare,” the brand expresses its expertise in refined craftsmanship and the pursuit of ultimate diamond brilliance.
Even the reflection of platinum is carefully calculated—resulting in absolute brilliance.
“St. Glare” expresses GINZA DIAMOND SHIRAISHI’s essence through refined craftsmanship and uncompromising quality.
Designed to maximize diamond brilliance, it features a highly precise setting that enhances light from every angle, including carefully calculated platinum reflections.
Inspired by a cathedral-like form, it represents a timeless love story and stands as a pinnacle of Japanese engagement ring design.


Refining my work every day, aiming to bring more customer smiles to
GINZA DIAMOND SHIRAISHI.

Do you have any memorable stories with customers that left a strong impression?
“Well, I’m usually quite indecisive, but I found it so quickly!” and “I really enjoyed my time in the store!” Hearing words like these truly makes me feel incredibly happy.
Also, when I was working at the Okayama store, a customer once said, “Please show me the diamond you personally think is the most beautiful—I want to give it to my girlfriend.” That made me extremely happy and left a lasting impression. This kind of trust from customers is what continues to motivate me in my work.
What is the ultimate goal as a consultant?
“The goal is for customers to leave with a brighter smile than when they arrived.”
Rather than an endpoint, this has been the unwavering mission since joining the company.
Even if no purchase is made, the aim is for every customer to spend a meaningful, happy time at GINZA DIAMOND SHIRAISHI. Going forward, we will continue to refine our skills to deliver deeper emotion and added value through every consultation.
What is the professionalism of GINZA DIAMOND SHIRAISHI that consultant

By uniting the perspectives of designers, buyers, and craftsmen, he sets a powerful example through how he faces every customer directly.
