Here the focus is on classic, vintage-inspired diamond jewelry, including engagement and wedding bands. For brides who want some serious bling — but only for the big day — earrings, necklaces, and bracelets are available to rent for a wedding weekend (from $300). A consultant can even bring selected pieces to dress fittings to ensure the jewels complement the gown. By appointment only.
