Antique Style Aquamarine Ring 15.37 Ct., 18K Yellow Gold

This ring centers on a 15.37 carat aquamarine, cut in a classic emerald shape, with precise dimensions of 17.98 by 13.23 by 8.98 millimeters. The faceting follows a traditional step cut hierarchy, with broad table and elongated pavilion steps that produce controlled light return and pronounced color zoning. The measured depth yields approximately 57.6 percent proportionality, a proportion that preserves the stone faceting integrity while maximizing face up presence. Clarity is graded as very very slightly included at eye level, indicating minimal internal characteristics that do not interrupt the step facet planes. Color displays intense saturation for aquamarine, a cool ocean blue with even distribution across the table and facets, enhanced by professional heat treatment. The polish is excellent, the facet junctions are crisp, and the truncated corners and straight girdle profile demonstrate careful cutting from material sourced in Brazil.

Complementary accents are two white round natural diamonds, totaling approximately 0.76 carats, each selected for Very Slightly Included clarity grades VS1 and VS2 and a high color grade of F. These round brilliant stones are positioned as flanking shoulder gems, their brilliant facet pattern chosen to contrast the step facets of the center stone, producing scintillation at each profile view. The mounting strategy minimizes metal intrusion, using prong settings that secure each diamond while allowing maximum light ingress and egress. The four corner prongs on the aquamarine are engineered with tight geometry to protect the stone corners, while the pierced gallery beneath the table promotes axial light return and reduces visual dead zones. All gemstones are set in 14 karat yellow gold, chosen for warm contrast and long term durability, with solder joints and peg fittings executed to a high tolerancing standard.

The overall design draws inspiration from architectural motifs and coastal forms, combining a structural gallery reminiscent of classical colonnade spans with filigree and vine like engraving that evoke sea grass movement. The shank is hand engraved and edged with milgrain, creating a textural interplay that reads as both engineered geometry and organic ornament. This synthesis of architectural proportion and natural rhythm results in a piece that sits balanced on the hand, engineered for comfort and longevity.
