The Story Behind This Ring

Oval Diamond with Half-Moon Side Stones

Half-moon side stones are a mid-century jeweler's secret — curved and elegant, they cradle the center stone like cupped hands, bringing a sense of occasion to the entire design.

The Harriet pairs this graceful combination with a stately oval diamond in a ring that captures the sleek sophistication of another era. A three-stone design that honors the past, cherishes the present, and opens like a new moon toward the future. For the classic bride whose beauty is quiet and timeless.

Oval diamond, half-moon accents, past present and future in one ring.

Five-Star Reviews

We had such a wonderful experience with Rustic and Main. The unboxing alone felt special—it came complete with a certificate of authenticity for the WWII M1 Garand Rifle Stock used in the inner inlay of my fiancé’s wedding ring. The craftsmanship was evident in every detail.
