To isolate an active portion of a gyroscope resonator from mounting stresses propagating through a resonator attachment center, the resonator includes a stress isolation feature that includes alternating concentric symmetric regions of high and low stiffness. The resonator may be separated into a large number of thin, compliant spring elements and larger stiff mass elements, the aggregate areas of which optimized for an aggregate resonator spring constant (by selecting a width and a length of the spring elements), an aggregate mass (by selecting a size of the mass elements), a thermoelastic loss maximum (by selecting a width of the spring elements) and an operating frequency (by selecting a ratio of the aggregate spring to the aggregate mass).
