Round Brilliant Solitaire Engagement Ring

This is a classic solitaire engagement ring featuring a round brilliant-cut colorless stone, which appears to be either a diamond or a high-quality stimulant such as cubic zirconia. The central stone is held securely by a traditional six-prong setting, often referred to as a 'Tiffany-style' mount, which maximizes light entry and brilliance. The stone is estimated to be approximately 1.5 to 2.0 carats in size based on visual proportions. The prongs are finished in a white metal—likely white gold or platinum—to blend with the stone, while the shank (band) is crafted from high-polish yellow gold. On the interior of the shank, a stamped marking is partially visible; it appears to read 'CZ' or a similar hallmark, which may indicate the stone type or a manufacturer's mark. The band features a flat-top profile with slightly rounded interior edges for comfort. The condition appears to be very good with minor superficial micro-scratching on the gold surface consistent with gentle wear. The craftsmanship shows precise symmetrical prong placement and a well-proportioned gallery height. The style is timeless, quintessential of late 20th-century to contemporary bridal jewelry design.

I have conducted a visual appraisal of this classic solitaire engagement ring. The piece features a round brilliant-cut stone, estimated at 1.5 to 2.0 carats, set in a six-prong white metal head with a yellow gold shank. My examination of the interior hallmark reveals a 'CZ' stamp, which strongly indicates the center stone is Cubic Zirconia rather than a natural diamond. While the setting appears to be gold, the presence of a stimulant stone significantly dictates the market value toward the lower decorative tier rather than the investment jewelry tier. The condition is very good, showing only minor surface abrasions consistent with light use. In the current secondary market, mass-produced CZ rings in 14k gold are common; value is primarily derived from the scrap weight of the gold shank rather than the stone or design rarity. As the appraiser, I must note that visual inspection via imagery cannot confirm gold purity or stone identity with 100% certainty. A physical examination using a thermal conductivity probe (diamond tester) and an acid or XRF test for gold karatage is required for a definitive valuation. Furthermore, checking for a '14K' or '10K' mark alongside the 'CZ' stamp would provide better clarity on the metal's intrinsic value. This estimate assumes the band is solid 14k yellow gold; if the item is gold-plated, the value would drop below $50.
