One of Arielle Ratner’s five core engagement designs, the Filo is all about movement of form.  The Filo is available in two styles, with or without a gap. Arielle had always been drawn to spherical shapes and their representation of infinity – a form without beginning or end. This style is especially complementary to antique cut stones, celebrating the individuality of Old Mined and Old European Diamonds.  If you are interested in creating a partially or fully customized Arielle Ratner engagement ring, please inquire within, or fill out our intake form on the ‘Engagement Series’ part of the site.
