The M. Hisae studio is constantly evolving to support sustainable, Earth-forward practices. At its core is a made-to-order production style and low-waste studio practice. I use a non-toxic liquid tumbling solution, fluoride- and chloride-free soldering flux, citric acid pickle, vegan polishing compound, and biodegradable ultrasonic cleaners. By incorporating these earth-friendly materials into my studio, my process, though sometimes slower, feels healthier and more environmentally deliberate.
I have chosen to use only Certified Post-Consumer Recycled and Antique Diamonds in my designs, in lieu of ethically-sourced, newly-cut material. This is an intricate stance that I have thought a great deal about. While industry-changing opportunities exist in supporting newly-mined material to monitor labor conditions, encourage environmentally-conscious mining, and trace origins, it is my personal belief that recycling is the more environmentally and socially beneficial choice. Though the recycled diamonds I select are guaranteed fair trade and sourced under ethical business contracts, it is true that the vast majority of recycled diamonds cannot be traced to their location origins or be determined conflict-free with certainty. However, as sustainability is defined, I choose to avoid further depletion of natural resources via the diamond industry's mining, transportation, and cutting facilities. This feels like the most sensible path, given the substantive pool of diamonds already in circulation. I feel the most pride knowing that my products are consciously avoiding waste and pollution.
My Certified Post-Consumer Recycled diamonds are acquired from trusted and verified sources of previously-owned, period, and estate jewelry. It is an unwavering, core principle of my work that diamonds and colored gemstones are guaranteed fair trade and ethically-sourced. All are meticulously inspected for quality and character. Origins of colored gemstones are freely provided within each product listing, in support of transparency and empowered buying.
Castings are produced in New York City from 100% recycled metals. I am currently working to transition all chains and findings over to 100% recycled metals - I will be pleased to notify everyone when this process is complete.
