Marquise Larimar and Marcasite Oxidized Silver Ring

This is a contemporary designer ring featuring a large, marquise-cut cabochon of Larimar as its centerpiece. Larimar, a rare blue variety of pectolite found only in the Dominican Republic, displays its characteristic 'volcanic blue' coloration with mottled white patterns resembling sunlight dancing on tropical waters. The central stone is held in place by stylized V-shaped prongs at the top and bottom points. The stone is surrounded by an asymmetric, teardrop-shaped halo or 'outer frame' that is pavé-set with numerous small, faceted marcasite stones. These marcasites provide a metallic, dark-grey luster that contrasts sharply with the soft blue of the Larimar. The metal appears to be sterling silver with a deliberate oxidation (blackening) around the marcasite settings to enhance their sparkle, a common technique in Art Deco-revival jewelry. The band is slim and also features marcasite accents on the shoulders. The craftsmanship is clean, indicating a high-quality mass-produced or boutique artisan piece from the late 20th or 21st century. The stone surface appears smooth with no visible cracks, and the setting shows no missing stones or significant wear, suggesting the item is in excellent condition. This piece combines organic gemstone beauty with a sophisticated, vintage-inspired aesthetic.

I have conducted a visual inspection of this contemporary marquise-cut Larimar and marcasite ring. The Larimar displays a desirable 'volcanic blue' with the signature mottled white patterning indicative of authentic Dominican pectolite. The stone is in excellent condition with no visible surface abrasions. The use of oxidized sterling silver and pavé-set marcasites creates a high-contrast, vintage-inspired aesthetic common in boutique artisan jewelry. Market demand for Larimar remains steady due to its single-source origin; however, as a semi-precious stone in a silver setting, its value is dictated more by designer appeal and craftsmanship than raw material scarcity. Comparables for such secondary-market artisan pieces typically range between $150 and $300 depending on the retail venue. Factors impacting value include the symmetry of the marcasite setting and the saturation of the blue in the Larimar. It is important to note that this appraisal is based on photographic evidence alone. I cannot definitively verify the silver's hallmark (e.g., .925) or confirm if the Larimar is a composite or natural stone without an in-person physical examination. To provide a certified authentication, I would require an acid test for metal purity, microscopic inspection of the stone's inclusions to rule out glass imitations, and provenance documentation from the manufacturer. Consequently, this valuation represents an estimated fair market value for a genuine piece in this style.
