Round Solitaire Diamond Engagement Ring

This item is a classic solitaire engagement ring featuring a single round brilliant cut colorless gemstone, likely a diamond, estimated at approximately 0.50 to 0.75 carats based on visual scale. The stone is secured in a four-prong 'illusion' or 'buttercup' style setting, which helps maximize the visual size of the center stone. The head of the ring appears to be made of white metal (possibly white gold or platinum) to blend with the stone's color, while the shank is a slim, polished yellow gold band, indicating a two-tone construction common in mid-to-late 20th-century jewelry. The shank is delicate and tapers slightly as it meets the head. Condition-wise, the ring shows signs of light wear consistent with regular use; there are minor surface scratches visible on the metal of the band, and some accumulation of debris is visible under the stone, suggesting it would benefit from professional cleaning. The prongs appear stable and intact, though a closer inspection would be required to ensure the stone is perfectly secure. No hallmarks or maker's marks are visible from this angle, but they would typically be found on the interior of the shank. The overall craftsmanship reflects a timeless, minimalist aesthetic popular for engagement jewelry since the mid-1900s.
