MIYAMA was founded in 2023 by Sakura Summer (maiden name: Hashimoto). When she found out that her current husband had given her a 0.8-carat natural diamond engagement ring that cost about 17,00 U.S.D., she was shocked at its excessive price. Then, after learning about the extraordinarily high price of natural diamonds and the problems that lie behind their sourcing, she began to think about the true value of gemstones.
She is also a mother of one, and lost her diamond wedding ring in the course of her daily chores. At the time, she felt bad about losing her high-priced ring and was unable to tell her husband for three months. She wished she had a more low-priced, easily wearable, and beautiful piece of jewelry. Then, in Arizona, where moissanite originated, she had a miraculous chance to meet moissanite and was captivated by its ethicality, amazing brilliance, and attractive price.
MMIYAMA was thus born out of a desire to allow more people to enjoy beautiful jewelry without compromising on quality and conscience at a reasonable price.
