AI Appraisal Estimate

A delicate slider pendant crafted from 18k yellow gold. It features an elongated, likely oval or freeform, cabochon-cut opal as the centerpiece, exhibiting visible play-of-color. The opal appears to be bezel or semi-bezel set. Above the opal, there is a single small round brilliant-cut diamond accent.

The appraisal value is based on the combination of 18k yellow gold content (75% pure gold), a central cabochon-cut opal gemstone, and a single small diamond accent. The primary value driver, beyond the gold, is the opal, whose worth is highly dependent on factors such as origin, type (e.g., Australian, Ethiopian), play-of-color intensity and pattern, body tone, clarity, and carat weight. The provided image shows an elongated opal with visible play-of-color, possibly blues and greens. The diamond is presumed to be a small round brilliant accent, typical for such designs. The slider style and overall craftsmanship also contribute to the value. This range represents an estimated fair market value. A detailed gemological examination by a certified gemologist would be necessary for a more precise valuation, especially regarding the opal's specific qualities and the diamond's characteristics.
