What affects the value of Star Sapphire Cocktail Ring?

How to Identify Star Sapphire Cocktail Ring?

• Examine the sapphire for a distinct six-rayed star pattern that moves across the surface when viewed under a single light source.
• Check the interior of the band for hallmarks indicating platinum or 14k/18k white gold, consistent with mid-century manufacturing.
• Inspect the surrounding halo for brilliant-cut diamonds, ensuring they are securely prong-set and possess high clarity.
