What Is Linde Star Ruby Ring Worth?

The typical price range for Linde Star Ruby Ring is $425 - $465 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

  • The presence and legibility of the original Linde 'L' logo significantly increases market value.
  • The condition of the 14k white gold mounting and the clarity of the flanking accent diamonds.
  • The sharpness and symmetry of the star's rays when viewed under a single light source.
  • Overall preservation of the cabochon surface, as scratches or chips can diminish the $425-$465 price point.

How to Identify Linde Star Ruby Ring?

  • Look for the signature 'L' hallmark engraved on the back of the stone or the inside of the 14k white gold band.
  • Examine the star effect; Linde Stars feature a crisp, perfectly centered six-rayed star that moves fluidly across the surface.
  • Verify the mid-century setting style, typically featuring a smooth cabochon cut flanked by small accent diamonds.
  • Check for the uniform, saturated red color characteristic of the Linde Air Products manufacturing process.

History of Linde Star Ruby Ring

Linde Stars were high-quality synthetic star sapphires and rubies created by the Linde Air Products division of Union Carbide from the late 1940s through the 1970s. They became an iconic mid-century jewelry staple due to their perfectly defined asterism, which was more distinct than most natural stones.
