Our Story

MIYAMA was founded in 2023 by a Japanese woman who is a mother of one when she found out the price of her natural diamond engagement ring and 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.

What's more, as a mother of one, she had lost her diamond wedding ring in the course of her daily chores. She felt so bad that she could not tell her husband for three months and wished she had a less expensive, more easily wearable and beautiful piece of jewelry. She had the opportunity to discover moissanite in its native state of Arizona, and was captivated by its ethical nature, wonderful brilliance, attractive price. Having found the right jewelry, she wanted more people to enjoy beautiful jewelry without compromising on quality and conscience.
MIYAMA was thus born out of a desire to allow more people to enjoy beautiful jewelry without compromising on quality or conscience at a reasonable price.

Specializing in lab-grown stones

As a Japanese company founded by a Japanese woman, MIYAMA is committed to bringing ethical and beautiful jewelry to you. Specializing only in lab-grown diamonds and moissanite, we are dedicated to offering you the highest quality and brilliance with no compromise in quality or conscience.

MIYAMA uses 100% recycled precious metals (gold, platinum, silver) in all its jewelry to reduce the demand for mining. MIYAMA also only deals in lab-grown diamonds and moissanite which are a more ethical and sustainable choice while being more affordable than mined, natural diamonds. We believe more people can enjoy them on a daily basis.

We wish that you can express yourself through the jewelry you always dreamed of.
