A semi-mount is a ring setting that already holds its accent diamonds and is ready for the center stone of your choice. It is the middle path between buying a finished ring and designing one fully from scratch: you get a beautifully made setting, and you decide the center diamond that goes in it. At MJ Diamonds, our semi-mount rings come in 10K and 14K white and yellow gold, and our jewelers can help you choose a center stone that fits your style and budget, then set it for you.

Semi-Mount Rings: Settings Ready for Your Center Stone
What Is a Semi-Mount Ring?
A semi-mount is a ring setting that comes with its side and accent diamonds already in place, but with the center left for a stone you select. The "semi" means it is partly complete: the design, metal, and accent stones are done, while the most personal choice, the center diamond, is still yours to make. This lets you control the size, shape, and budget of the center stone while starting from a setting you already love. It is a popular choice for couples who want a custom feel without having to design every detail from scratch.


Why Choose a Semi-Mount
A semi-mount gives you the best of both worlds. You start with a finished, professionally made setting so you can see the look and accent diamonds in person, then choose a center stone to match your taste and budget. That means you can put more of your budget into the center diamond, or save by choosing a smaller or different stone, without giving up the setting you want. Our jewelers can walk you through center stone options, show you how different shapes and sizes look in the setting, and set the stone for you.
Choose Your Center Stone
The center stone is where a semi-mount becomes yours. Round is the timeless, brilliant choice, while shapes like oval, princess, pear, and cushion each give a different look in the same setting. Larger stones make more of a statement, while a smaller center keeps the focus on the setting's detail and is easier on the budget. Bring your ideas, or let our team guide you, and we will help you see real options in the setting before you decide.


Real Diamonds and In-House Setting
The diamonds in our semi-mount settings are genuine, not cubic zirconia or simulated stones, set in real 10K and 14K gold. Because setting a center stone is precise work, our full-service repair center and on-staff jewelers handle it in house, along with sizing, future repairs, and free jewelry cleaning. That hands-on service is part of how we have served couples since 1979.
