1.28 Ct. Bluish Green Sapphire from Australia

This 1.28 carat emerald cut bluish green sapphire from Australia, offered by The Natural Sapphire Company, combines precision cutting with natural color intensity and reliable durability. The stone measures 7.05 by 5.30 by 3.61 millimeters, yielding a depth proportion of approximately 58.5 percent, a proportion that balances face up table size with internal color saturation. The emerald cut employs a step facet architecture on both crown and pavilion, producing broad, parallel facet planes that emphasize the gem's intense bluish green hue rather than scintillation. This faceting style produces a hall of mirrors effect that showcases the stone's even color distribution, and the excellent polish results in crisp facet junctions and clean light return. Clarity is graded as very slightly included at eye level, meaning that inclusions are minor, well localized, and do not materially detract from the transparent appearance under normal viewing, an ideal characteristic for a step cut where clarity is paramount. The sapphire has been heat treated to optimize color and clarity, a stable and widely accepted enhancement that increases color uniformity without compromising structural integrity.

From a durability perspective this sapphire is exceptionally well suited to daily wear in finished jewelry, because it is corundum, the mineral family that rates nine on the Mohs scale, providing superior resistance to scratching and surface abrasion compared with most gemstones. The robust crystal structure delivers dependable toughness, and when combined with the durable nature of heat treatment, this stone tolerates routine cleaning and the rigors of daily use. For ring applications where impact exposure is greatest, we recommend settings that offer protection to the corners and girdle, such as a low bezel or secure multi prong work, which preserve the step cut silhouette while minimizing risk from hard knocks. Routine care consists of warm soapy water and a soft brush for regular cleaning, periodic inspection of the mounting to ensure prongs remain secure, and professional maintenance as needed. This combination of intense natural color, careful step faceting, excellent polish, and corundum hardness makes this Australian sapphire an outstanding choice for clients seeking a technically refined gem for everyday jewelry.
