12 Carat Lab-Grown White Sapphire Studs with Argentium® Silver Earring Jackets
Bring warmth and sophistication to your look with these 12 carat total weight lab-grown white sapphire oval studs. Each earring features a brilliant, eye-clean 6 carat AGTA lab-grown white sapphire, hand-set in traditional silver with elegant oval premium Argentium® silver hoop earring jackets. The jackets are detachable—perfect for styling versatility at shows or in everyday wear.
Lab-grown white sapphires are real sapphires—chemically, optically, and physically identical to natural ones—but created in a controlled lab environment rather than formed in the earth over millions of years. These gemstones offer exceptional brilliance and durability, making them a stunning and ethical alternative to traditional diamonds. Their icy-white clarity and radiant sparkle make them a favorite for minimalist luxury and timeless elegance.

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 Argentium® Silver?
Argentium® silver is a premium silver alloy that is more pure than traditional sterling silver. Earlier Argentium® silver formulations contained 93.6% pure silver, and in 2024 the alloy was updated to 94% purity.
California artist Lisa Ramos uses Argentium® silver in select MONOLISA handmade jewelry designs because of its durability, brightness, tarnish resistance, and refined appearance.
Argentium® silver is also valued for being hypoallergenic. The Argentium® silver used in MONOLISA designs is made in the USA and ethically sourced.

My mission is to design beautifully handmade limited-edition pieces that add a touch of elegance to any personal style. Each design is an extension of who I am.
