There are 14 steps that go into making Argentium silver earring jackets. In this video Lisa shows you her process.
THE HANDMADE PROCESS
The classic earring style is a true work of art. The jewelry piece is handcrafted personally by artist, Lisa Ramos in her Clayton, California studio. Lisa's design philosophy is focused on creating high quality jewelry pieces you can wear for years to come. What makes a MONOLISA jewelry piece unique? Each earring jacket is a one of a kind made piece 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, texturing, sanding, buffing, multiple hours of heat hardening the Argentium silver to increase the tarnish resistance properties, stone setting and polishing. The MONOLISA Collection is not mass produced or sold in retail stores. Pieces from the collection can only be purchased on this website or at a show. The MONOLISA Jewelry Collection has been featured at fine art juried shows in California. Lisa's mission is to design beautifully handmade limited edition pieces that add a touch of elegance to any personal style.
What is the meaning of a Sapphire?
It is one of the birthstones for September and in ancient times, some believed that the sky itself was an enormous sapphire into which the Earth was embedded; sapphires are credited in folklore as being sacred, of conveying wisdom, prophecy and divine favor. A sapphire is both the modern and traditional birthstone for the month of September. The colorless blue sapphire is a great alternative to a diamond for the birthstone month of April.
