What Is Star Ruby and Diamond Ring Worth?

The typical price range for Star Ruby and Diamond Ring is $1,200 - $1,500 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The intensity and sharpness of the 'star' effect significantly impact the market value, with more defined rays commanding higher prices.
• The origin of the ruby, with specimens from Myanmar (Burma) or Sri Lanka typically fetching a premium over other sources.
• The overall color and transparency of the ruby, ranging from pinkish-red to deep red, alongside the total carat weight of the diamond halo.
• The condition of the white gold setting and the presence of original vintage components from the 1950s-1970s era.

How to Identify Star Ruby and Diamond Ring?

• Examine the ruby for a distinct six-rayed star effect caused by rutile needle inclusions, which should move across the surface as the light source shifts.
• Check the interior of the white gold band for hallmarks indicating the gold purity and possible manufacturer marks from the USA or Europe.
• Verify the cabochon cut of the ruby, as this smooth, rounded shape is essential for displaying the asterism effect properly.
• Inspect the diamond halo setting for consistent prong work and stone quality typical of mid-20th-century craftsmanship.

History of Star Ruby and Diamond Ring

Star rubies are unique due to a phenomenon called asterism, where a six-rayed star appears to glide across the surface of the gem when illuminated. This optical effect is caused by inclusions of rutile needles oriented in specific directions. The use of star rubies in jewelry dates back centuries, often prized for their mystical qualities and rare beauty. Such halo settings, where smaller diamonds frame a larger central gemstone, became particularly popular in the early 20th century and have remained a classic design choice, enhancing the main stone's brilliance and size.
