Most RMJ designs use standard (with ball and coil) or minimalist style in stainless steel or gold-plate; see individual listings for details.
If you'd like to change the offered earwire, select the appropriate style here. There's no fee for most stainless steel and gold-plate swaps.
Upgrade fees apply for screw back designs, and for all styles in sterling silver, gold-fill or hypoallergenic niobium/titanium. Note that not all styles are available in all metals.
Niobium is available in a few select colors (they won’t match the aluminum exactly, due to differences in how the colors are achieved, but often work perfectly well.)
If you have any questions or are looking for a style not shown, please let me know.
