Diamond

Why we are called
"Diamond Kashikey"

The experience, conviction, and pride of the diamond dealers who have inherited Kashikey's DNA. Since the company’s founding, Kashikey has dealt in beautiful items that women can adorn, and they were the first to enter the diamond business in the 1960s, establishing posts throughout the world. Developing trust with local suppliers, they have come to dominate in their ability to obtain fine quality materials.

Selling the best quality goods at reasonable prices, Kashikey has also made it their mission to form the foundation of the jewelry culture in Japan, and even now, they devote themselves to the development of the industry.

Kashikey's pursuit of perfection extends to melee diamonds

Of course Kashikey is particular about the larger sized diamonds that form the face of a single piece of jewelry, but their pursuit of perfection extends even to the melee diamonds that perform a supporting role.
Kashikey has established its own original standards for proportion and cut, thoroughly paying attention to beauty. Their fastidiousness about even small details allows them to bring out a unique brilliance in their diamonds.

"Mazal U'Bracha"
In the world of diamond transactions, there is a unique custom of praising one another

At the site where diamond transactions are made, when negotiations are completed, brokers and buyers say to each other, "Mazal U'Bracha," which means "good luck and good fortune" ("mazal" means "fortune" in Hebrew). Regardless of each person's nationality, this phrase is used throughout the whole world and transactions are completed based on whether both parties find each other to be trustworthy or not, without the creation of contracts. During negotiations, one’s transaction partner is strictly judged based on, of course, the company he or she is affiliated with, but also based on whether that person is deemed trustworthy as an individual.
