Three Stone Blue Sapphire Ring 1.70 Ct., 10K Yellow Gold

This ring centres on a transparent 1.70 carat blue sapphire cut in an emerald silhouette, with precise dimensions of 7.95 by 5.39 by 4.00 millimetres. The sapphire exhibits vivid colour saturation and an excellent polish that reinforces the clarity and depth of tone characteristic of fine Ceylon origin sapphires. The clarity grade is recorded as very very slightly included, evaluated at eye level, indicating only minor internal features that do not detract from the stone's visual appeal when worn. Flanking the centre sapphire are white asscher, octagon shaped natural diamonds, with a total weight of approximately 0.70 carat, colour grade F, and clarity grades of Very Slightly Included in the VS1 and VS2 range, selected to complement the sapphire with crisp, high colour and clean brilliance. The mounting is executed in 18K yellow gold, chosen for its warm contrast to the blue sapphire and for the refined balance it provides between strength and luxurious finish.

From a durability standpoint, this piece is engineered for regular wear while maintaining the integrity of its gemstones and setting. Sapphire, as a gem species of corundum, rates 9 on the Mohs hardness scale, second only to diamond at 10, which gives it superior resistance to surface scratching in everyday activities compared with many other gemstones. The two natural diamonds beside the sapphire are the hardest gem material, rated 10 on the Mohs scale, and they contribute durable accent brilliance while resisting abrasion. In terms of structural toughness, corundum lacks a true cleavage plane, which reduces its propensity to split along specific directions, although like all hard gemstones it can sustain chips or facet edge damage from concentrated impact. The asscher cut diamonds, while durable by nature, are faceted with broad pavilion steps, which means that their corners and edges are protected by their position in the shoulder settings, minimizing exposure to knocks.

The ring’s setting design and metal choice further enhance its suitability for daily wear. The 18K yellow gold band offers a robust framework with a slightly higher gold content than lower karat alloys, providing a rich colour while remaining sufficiently durable for everyday use when properly maintained. The sapphire is secured with prongs that lift it above the gallery for light performance, while the side diamond settings are positioned to shield the sapphire’s shoulders and reduce direct lateral impact. This combination of a high hardness centre stone, resilient diamond accents, and a solid 18K gold mounting provides a practical balance of beauty and wearability. For activities that involve heavy manual labour or exposure to harsh chemicals, removal of the ring is advisable, as repeated abrasion and chemical exposure can alter metal finish and, in extreme cases, affect the surface of any gemstone.

Care recommendations are straightforward and tailored to preserve the ring’s condition over time. Regular inspection of prongs and the gallery by a qualified jeweller will ensure settings remain secure, and annual professional cleaning and tightening are recommended to maintain brilliance and structural integrity. For routine home care, gentle cleaning with warm water, a mild detergent, and a soft brush will safely remove everyday soils, and ultrasonic cleaning may be appropriate for an untreated sapphire and for securely set diamonds, however any suspected or disclosed treatments should be confirmed before using ultrasonic methods. Avoidance of harsh household chemicals, prolonged exposure to extreme temperatures, and strong lateral impacts will reduce the risk of surface wear and accidental damage. The Natural Sapphire Company craftsmanship places emphasis on both gem quality and setting longevity, delivering a ring that combines Ceylon sapphire provenance, expertly matched asscher diamonds, and a considered 18K yellow gold mount to meet the expectations of those seeking a refined yet durable piece for everyday wear.
