Jewelry Design Hortensia Bouquet Ring by Nina Vidmar The design of the Hortensia Bouquet floral gemstone ring represents the contemporary design aesthetics combined with the ancient technology of the lost-wax process. Crafting a classic expression of diamonds and precious gemstones, the Hortensia Bouquet ring is formed of 18K rose and white gold hydrangea petals with blue sapphire centers, which encircle a vibrant jeweled cupola. Shades of pink and blue sapphires surrounded with diamonds form the dome of this statement ring. A blend of hand chosen gems and time honored craftsmanship.
