Visual Centerpiece

A square-cut natural amethyst, reminiscent of a field of preserved lavender, rests atop a three-tiered French arch setting. The adjustable open shank is ingeniously concealed within wave-patterned gold filigree. In a harmonious trio of silver, gold, and purple, it interprets the elegant variations of neo-classical style.
