Heart-shaped pendant consistent with gold-toned metal and colorless stones

This item is a small heart-shaped pendant, styled as an open-heart halo design. It appears to be constructed from a gold-toned metal, which is consistent with yellow gold or gold-plated base metal. The perimeter of the heart is bezel-set with fourteen small, round-cut colorless stones that are consistent in appearance with diamonds, cubic zirconia, or white sapphires. Each stone is held by simple rounded prongs within a scalloped outer border. The center of the heart is hollow with a polished inner rim. It hangs from a tapered polished bail by a thin cable-style chain. No visible maker's marks, hallmarks, or metal purity stamps (such as "14K" or "925") are readable in the image, meaning the material composition cannot be determined without physical testing. The craftsmanship shows a high-polish finish with some visible surface scratches and minor tarnish appearing in the crevices between the stone settings, suggesting regular wear. The aesthetic is consistent with late 20th-century or contemporary fine jewelry styles common in mass-market or boutique retail. Because no identifying branding is visible, this attribution remains a stylistic hypothesis based on visual characteristics alone.

Based on the provided image, I observe a small heart-shaped pendant featuring an open-heart halo design, constructed from a gold-toned metal and set with small round-cut colorless stones. The item shows minor surface scratches and tarnish in the crevices. Because there are no visible maker's marks or metal purity stamps, I cannot determine the actual material composition from a photograph alone. The piece bears stylistic similarities to late 20th-century or contemporary retail jewelry. My primary valuation of $150 to $350 represents an estimate for an item of this type if the hypothesis holds that it is crafted from 14k gold and genuine diamonds. However, open-heart halo pendants are widely manufactured in costume materials. If this piece is constructed of gold-plated base metal set with cubic zirconia or glass simulants, the secondary market value would drop to the $15 to $40 range. The broader market for such pieces is saturated, meaning value is heavily dependent on the intrinsic worth of the materials rather than the general design. To establish the precise composition and narrow the valuation, in-person examination by a qualified jeweler is required, including electronic gem testing and metallurgical analysis such as acid testing or XRF.
