Handmade Argentium Silver Gemstone Ring Collection - designed with beautiful gemstones which include white sapphire, tanzanite, various topaz, ruby and amethyst. What makes a MONOLISA gemstone ring unique? It is a one of a kind ring that isn't casted - pouring molten metal into molds for mass production. The handmade design is an extensive process of sawing metal pieces, hand sculpting, soldering, hammering, sanding, buffing, stone setting and polishing to create a high quality piece you can wear for years to come. Each ring is personally hand crafted by designer, Lisa Ramos.
