10.55 Ct. Blue Sapphire and Natural Diamond Antique Style Ring, Platinum 950

This ring centers on a GIA certified, untreated Ceylon blue sapphire weighing 10.55 carats, presented in a radiant shape with dimensions of 12.07 by 8.51 by 9.43 millimeters and a mixed brilliant cut. The sapphire displays a vivid color intensity, an excellent polish, and a clarity graded as very slightly included when evaluated at eye level. Surrounding the center stone are 36 natural, round brilliant cut white diamonds that total 1.13 carats, with a clarity of VS2 and an F color grade. The mounting is crafted in platinum 950, providing a dense and durable metal setting that resists deformation and retains its form under regular wear. This composition of an untreated Sri Lankan sapphire, precision cut diamonds, and a platinum 950 mount embodies the technical quality standards upheld by The Natural Sapphire Company.

In assessing durability for daily wear, the sapphire performs exceptionally well relative to most colored gemstones due to the inherent hardness and toughness of corundum. On the Mohs scale of mineral hardness, sapphire ranks at nine, making it second only to diamond in practical scratch resistance among commonly used jewelry gems. This means the sapphire resists surface abrasion from everyday materials and will maintain its polished facets longer than gems with lower hardness such as topaz and emerald. Compared to diamond, which rates ten on the Mohs scale, sapphire is slightly more susceptible to surface abrasion but remains highly resistant to scratches in normal use. Toughness, which measures the stone resistance to chipping and fracture, is also favorable for corundum because it lacks perfect cleavage planes, however sharp blows to facet junctions or the girdle can still cause chipping. The halo and diamond shoulder arrangement on this ring reduces direct exposure of the sapphire girdle and corners to blunt impact, thereby improving the practical durability of the setting for daily use. The 36 round diamonds contribute both optical brilliance and an additional protective frame, while their own hardness at ten on the Mohs scale ensures they retain sparkle under routine conditions, noting that careful setting maintenance is important to prevent loosening.

Platinum 950 further enhances the ring resiliency for everyday wear, because the alloy combines strength with ductility which allows the metal to absorb impact without brittle failure. Platinum also develops a natural patina over time which can be polished back to restore a bright finish, and it offers hypoallergenic properties for sensitive skin. For long term performance, basic care practices preserve the integrity of both stone and setting, these include removing the ring during heavy manual activities to avoid blunt trauma, avoiding exposure to harsh chemicals which can affect metal and any filler materials even though this sapphire is untreated, and scheduling professional inspections at least annually to confirm prong security and tightness of the diamond accents. Gentle cleaning with warm soapy water and a soft brush will remove surface oils and dust without damaging the sapphire or diamonds. The combination of a hard, untreated Ceylon sapphire, high quality round brilliant diamonds, and a platinum 950 mounting results in a ring that is well suited to daily wear when cared for with routine attention and periodic professional maintenance, and it is presented and documented by The Natural Sapphire Company.
