Nadja, inspired by the female womb, is a popular item among people of all ages.

Naja necklaces are jewelry pieces created by the Navajo and Zuni tribes from the 1930s to the 1980s, and are sacred and indispensable to tribal ceremonial attire. The pendant is a mystical piece of jewelry said to be modeled after either a woman's womb or a crescent moon. The part in the chain called a squash blossom is modeled after a pumpkin flower, and is said to symbolize a bountiful harvest, combining the womb of Mother Earth with the pumpkin flower. The vintage turquoise rings, dating from the 1930s to the 1990s, show different colors depending on the mine. The deep hues ranging from blue to green vary depending on the source, and each one has its own unique charm.

"When I started going to Rose Bowl and Sedona for buying trips, I developed closer relationships with the people there. I've had several mystical experiences. I don't mean to imply anything, but the more I go there, the more I feel a kind of power drawing me in. Lately, I get a little tired after going. I buy jewelry and turquoise that catches my eye there for myself, but there are some that make me hesitate when I hear the price. Even so, the things I decide on after going there twice have a special meaning for me."

The collection also features a wide selection of vintage squash blossom necklaces and turquoise bangles.

Drawn in by some mysterious force, he is captivated by jewelry and has visited the shop countless times. Mr. Kumagai, who never became obsessed with Goro's or Chrome Hearts in the 90s and only discovered the allure of turquoise after turning 40, says that Native American jewelry suits adults of a certain age. He also says that it suits older women better than younger girls.
