This sterling silver tube setting holds one round faceted gemstone. Pre-formed seats provide a professional start to stone-setting and help ensure level setting—complete the setting by adjusting the seat to fit your individual stone using a setting bur. Check your stone size carefully; because gemstone sizes vary within a certain tolerance, the setting may need to be adjusted for your stone.
Tube settings are literally cut from (or, as in this case, cast as) a tube with enough thickness to accommodate the built-in seat for the gemstone. The setting is finished in roughly the same way as a bezel; the tube walls are pushed inward and burnished over the girdle of the stone to hold it securely in place.
• IMPORTANT: Sterling silver is an alloy containing metals that react with chemicals found in air and produce tarnish; high moisture levels, exposure to sunlight and contaminants such as salt water increase this reaction. Take steps to protect your sterling findings by keeping them in airtight packages, use tarnish-resistant products (such as tarnish tabs or strips) that absorb harmful chemicals, and store sterling findings in a cool, dry place. Most tarnish is easily removed by polishing with a mild abrasive or soaking in an anti-tarnish solution.
