Custom Ring Studio
A Personalized Experience Rooted in Story, Craft, and Intention.
Welcome to the LMJ Online Ring Studio — where your story takes shape.
We’ve partnered with Misfit Diamonds, curators of ethically sourced and beautifully unconventional stones, to give you direct access to a thoughtfully selected inventory of unique sapphires and diamonds.
Now, you can handpick your perfect stone and pair it with one of our signature LMJ settings to create a ring that feels unmistakably like you.
How it Works
-
1. Choose Your Stone
Misfit GemsBrowse our live inventory from Misfit Diamonds—updated in real time—and select the shape, size, and style that speaks to you. From moody salt-and-pepper diamonds to vibrant teal sapphires, every stone is ethically sourced and full of soul. Once you've selected a stone you can then shop our available settings or book a consult to design something around the stone.
-
2. Select Your Setting
Find your settingExplore a curated collection of LMJ's signature settings—crafted in 14kt or 18kt gold, designed to balance everyday wear with heirloom quality. Most gemstone shapes & sizes will work with these designs, with more guidance on stone selection in the description. For diamonds over 2ct, please contact us before proceeding as additional customizations might be necessary.

3. Bring It All Together
Book a custom consulationOnce you’ve purchased your stone and setting, we’ll confirm your order and begin handcrafting your ring in our Cleveland Heights studio. You’ll receive a detailed timeline and be looped in every step of the way. You can book a consultation if you'd rather work with LMJ one-on-one for stone selection or design after you've picked a stone.
