Solitaire Greenish Blue Sapphire Ring 2.55 Ct., Platinum 950

This ring from The Natural Sapphire Company centers on a superb, transparent 2.55 carat oval greenish blue sapphire, presented in a mixed brilliant cut to optimize scintillation and table brightness. The stone measures 7.72 x 6.83 x 6.00 mm, a proportion that provides a strong face up presence while maintaining excellent depth for light return. At the loupe and at eye level the sapphire is graded very slightly included, which means inclusions are minimal and do not interrupt its transparency or its lively surface brilliance. The color is described as having intense saturation, a deep even greenish blue that reads richly in both daylight and artificial lighting, and the polish on the pavilion and crown is excellent, ensuring crisp facet junctions and strong light performance. Importantly, this sapphire is unenhanced, a characteristic that significantly increases its rarity and desirability in the current market, and it is of Madagascan origin, a region known for producing gems with vivid color and clean crystal habits.

From a gemological and grading perspective, several attributes make this piece notable to an educated buyer. The mixed brilliant cut combines step and brilliant facet relationships, which increases return of light from the pavilion and preserves color saturation in the crown area. The proportions indicated by the dimensions give an ideal balance between surface area and depth, producing a lively apparent size relative to its 2.55 carat weight. Clarity graded as very slightly included at eye level indicates that inclusions are confined, and that the stone maintains excellent transparency and brilliance without the need for filling or other stability treatments. The absence of heat treatment or other enhancement is a critical value driver, because most commercial sapphires are routinely heated to enhance color. An unenhanced stone of this quality commands a premium, because its color and clarity are entirely natural, preserved from formation to setting with no artificial intervention.

When comparing this greenish blue Madagascar sapphire to stones found in more famous or historically notable rings, the distinctions that matter to a connoisseur are color origin, treatment history, and overall balance of clarity and cut. Kashmir sapphires are celebrated for a velvety cornflower blue and a soft glow caused by silk inclusions, and while those stones occupy the apex of historic desirability, they are exceedingly rare and typically much more expensive per carat. Sri Lankan or Ceylon sapphires often show a lighter, brighter blue with open clarity, and Burmese stones can show strong, saturated tones. Australian sapphires tend toward deeper blue green or teal, sometimes with darker body color and more inclusions. The Madagascar stone in this ring combines an intense greenish blue saturation that is deeper than typical Ceylon tones, yet clearer and more brilliant than many darker Australian examples. Because it is unheated, it sits in a market segment prized by collectors who seek natural color and documented provenance, even when competing against larger or historically famous stones that may have undergone treatment to modify their appearance.

The ring setting enhances both the aesthetic and practical value of the sapphire. The mounting is executed in platinum 950, a high purity alloy chosen for its strength, hypoallergenic properties, and ability to support secure prongs while providing a cool reflective backdrop that complements blue and greenish blue hues. The design places the oval stone in a classic solitaire style with a sculpted head that allows maximum light to reach the pavilion, which in turn maximizes scintillation and perceived color depth. For an educated buyer considering longevity and wearability, platinum 950 offers superior resistance to bending and wear when compared to lower karat gold, and it maintains its finish over time with modest maintenance. The combination of a naturally intense, unenhanced Madagascar sapphire and a durable platinum setting produces a ring that has both immediate visual impact and long term value retention, especially when accompanied by gemological documentation and the provenance assurances provided by The Natural Sapphire Company, including our commitment to ethical sourcing and independent verification upon request.
