Conversely, a faint, blurred, or off-center star diminishes its appeal and value. Rings featuring stones with prominent and symmetrically aligned stars command higher prices.
- Color and Saturation
Star sapphires occur in a range of colors, including blue, gray, black, and purple. The intensity and purity of the color, known as saturation, play a critical role in gem quality. Deeply saturated, evenly colored stones are generally more valuable than those with muted or inconsistent coloration. The most sought-after blue star sapphires exhibit a rich, velvety hue.
- Clarity and Inclusions
While the asterism effect is caused by microscopic inclusions within the sapphire, excessive or prominent inclusions can detract from the gem’s overall beauty and clarity. A balance is desired: enough inclusions to create a distinct star effect, but not so many that the stone appears cloudy or opaque. Stones with minimal distracting inclusions are considered higher in quality.
- Size and Cut
The size of the star sapphire, measured in carats, influences its value, with larger stones generally being more expensive. The cut of the cabochon (a polished, unfaceted gem) is also important. A well-proportioned cabochon with a smooth, symmetrical dome optimizes the star’s visibility and enhances the gem’s overall aesthetic appeal. An asymmetrical or poorly shaped cabochon can distort the star and diminish its value.
The combined effect of these characteristics star definition, color saturation, clarity, and size dictates the overall quality of the star sapphire and, consequently, the value of the ring. Rings featuring sapphires with exceptional gem quality are highly prized by collectors and represent significant investments.
3. Setting Style
The configuration holding the star sapphire, termed the setting, is an integral component of the design and overall value of a vintage ring. The setting not only secures the gem but also significantly contributes to the ring’s aesthetic and historical character.

Distinctions in metal purity can also serve as indicators of a ring’s age and origin.
- Hallmarks and Assaying
Hallmarks, stamped markings on the metal, are primary indicators of purity. These marks, often indicating the karat value of gold (e.g., 14K, 18K) or the fineness of platinum (e.g., Pt950), provide verifiable information about the metal’s composition. The presence or absence of hallmarks, as well as their specific style and content, can assist in determining the ring’s origin and age. Assaying, a chemical analysis of the metal, offers an independent verification of purity when hallmarks are absent or questionable. A ring represented as 18K gold should, upon assay, confirm a gold content of 75%.
- Gold Alloys and Color Variations
Gold, in its pure form (24K), is too soft for jewelry applications. It is therefore alloyed with other metals to enhance its durability and alter its color. The type and proportion of these alloying metals affect the resulting gold color and its resistance to scratching and denting. Yellow gold alloys typically include silver and copper, while white gold alloys often incorporate nickel or palladium. Rose gold achieves its pinkish hue through the addition of copper. The specific alloy used in a vintage ring can offer insights into the manufacturing practices of the period.
