Incorporating natural symbols of guidance from high above, the series represents infinite love that is as faithful as the orbiting moon and as unconditional as the ever-present stars. Wholeheartedly designed for the person who never fails to brighten your day, Luna is your chance to forever illuminate her life.

Astonishingly beautiful craftmanship and a team determined to fulfil their promises!

We could not be happier with the Luna engagement ring and wedding band set we bought. The service we received was impeccable as well. The rings: We customized the stones, the metals, everything, and the team could not have been more informative and helpful. Every question was answered in detail and I was even given information about how the stones would age. The craftmanship is incredible and my rings are truly flawless. The service: The team went through a lot while we were having this made! A machine broke down and a storm destroyed their studio but they kept in touch, advised us of the delays and delivered exactly what they said they would. All of my requests for customisation were included without question and at no extra cost. It was shipped around the world very quickly too. I would also like to add that I asked a lot of probably irritatingly in-depth questions and was always answered promptly with friendly, polite, and accurate answers. There needed to be an alteration made to the design in order to secure the particular stone I had, and I was offered a variety of options along with their personal recommendations. You can tell they care about how long your investment will last you and how beautiful the finished product is. whenever anyone asks me about my ring or mentions jewellery at all I feel obligated to tell them about Michelia because of how astonishingly beautiful their craftmanship is, how beautiful their designs are and how determined they were to work through a natural disaster!
