Antique Style Blue Sapphire Ring 4.03 Ct., 18K White & Yellow

The ring centers a transparent 4.03 carat oval blue sapphire, measured at 11.69 x 8.86 x 4.83 millimeters, with a mixed brilliant cut that combines pavilion faceting for depth with crown faceting for face up brilliance. The stone is sourced from Ceylon Sri Lanka, and displays vivid color saturation and an excellent polish, attributes that contribute to strong presence and lively interaction with light. Clarity has been evaluated as eye clean at typical viewing distance, and the stone has undergone standard heat enhancement to improve color uniformity and stability. The proportions and finish of the facet junctions indicate careful lapidary work, and the oval outline preserves the stone weight while maintaining elegant finger coverage. The Natural Sapphire Company presents this piece with full disclosure of origin and enhancement, aligning with common trade practice for sapphires of this class.

Surrounding the center sapphire is a halo and accent arrangement of white round natural diamonds, set to complement the blue center without overpowering it. The primary grouping of diamonds totals approximately 0.33 carat with clarity graded VS and color graded F G, and an additional grouping totals approximately 0.09 carat with the same clarity and color range. Cut quality for these melee diamonds is consistent with their grades, producing even scintillation and contrast around the sapphire. The setting combines 18 karat white gold in the head and halo areas to enhance the apparent whiteness of the diamonds, with an 18 karat yellow gold shank that provides warm contrast and traditional hand feel. The gallery features openwork that reduces weight while allowing light to enter the sapphire from the sides, and the prong architecture secures the oval without excessive metal covering the girdle.

When compared to gemstones in more famous rings, the sapphire in this ring exhibits characteristics that align with high quality Ceylon sapphires commonly admired in notable collections. Color intensity is vivid rather than pastel, and the transparency and eye clean clarity place it among stones preferred for prominent jewelry. In museum pieces or royal jewels, one often finds either larger unheated sapphires of historical significance or smaller stones with exceptional provenance. This sapphire, at 4.03 carats with vivid saturation and excellent finish, offers a contemporary balance of size and optical performance that is comparable to many celebrated examples, while recognizing that some famous stones are prized for rarity due to lack of enhancement or unique historical context. Heat treatment is an accepted and stable enhancement in the trade, routinely applied to Ceylon material to produce the most desirable blue hue, and it does not detract from the gem s overall merit when disclosed as is the case here.

The overall construction and material selection reflect considered design and gemological standards, with the two tone 18 karat gold composition used to both support and showcase the sapphire and diamonds. The dimensions of 11.69 x 8.86 x 4.83 millimeters yield a substantial face up area that reads larger on the finger than weight alone might suggest, and the mixed brilliant cut contributes to lively return of white and blue light. For a client comparing stones of similar carat weight and origin, this sapphire s combination of vivid color, eye clean clarity, and meticulous polish positions it as a strong example of quality gems available today. The Natural Sapphire Company documents origin and enhancement, and delivers this ring with an emphasis on accurate, transparent description of its gemological attributes.
