A rich royal blue sapphire, weighing 4.75 carats, cut with an extra-large table to accommodate a hand- carved coat of arms--a British lion atop a shield--is flush-set in a plain, classic 18K signet style ring in this rare and refined vintage jewel (circa early-20th-century). Accompanied by a gemological report from Stone Group Laboratories stating: Natural. No Indications of Thermal Enhancement. Sri Lanka (Ceylon) - origin. Now, and forever, ring size 8. Condition note: The sapphire has a small chip at the upper right edge, as well as an internal stress fracture, which presumably has been there since time immemorial, however, under the circumstances it would be safest to to leave well enough alone and not tempt fate with the high heat required for resizing. Left alone, there's no reason it shouldn't enjoy a healthy life for at least another century or two.

About Vintage Jewelry

Like fine wine, fine jewelry also has a “vintage”—the design period or era from which it hails. Victorian or Edwardian, Art Deco or Retro, each piece in our collection has its own special pedigree. But just because one era ended and another began, it doesn’t mean that creative jewelry makers simply forgot the lessons of the past! Many of the jewels in our cases refuse to conform to a single design period, either by striking out on their own or showing the transition from one era to the next. When such daring dazzlers are over one hundred years old, they’re generally grouped in the antique category. Anything younger than that, but still made before 1970, fits the vintage label. Every iconic era yields both singular and transitional pieces, like the ones we’ve assembled here. Follow the link at the end of each section for more about the aesthetics and history of the period.

Jewelry Care

As with anything of value, especially sentimental value, taking good care of your vintage and antique jewelry from Lang will enhance its beauty and extend its lifespan. We encourage you to have your jewelry checked and cleaned by us or by your trusted local jeweler every six months, to ensure that each piece is in good wearable condition with all gemstones in place. It’s not uncommon for stones to loosen over time, and it’s much easier to tighten a loose stone than to replace a lost one! As stated in our Repair Policy, we strongly recommend that you allow us to perform any repairs, since our jewelers are specialists in restoring vintage and antique jewelry.
