1.57 Ct. Bluish Green Sapphire from Australia

This 1.57 carat bluish green sapphire from Australia is a striking example of natural corundum, presented in a carefully proportioned fancy shape with dimensions of 7.31 by 7.09 by 5.05 millimeters, a mixed brilliant cut, intense color intensity, and an excellent polish. The stone is transparent and has been evaluated as very slightly included at eye level, which attests to its clean appearance to most viewers while preserving the natural characteristics that collectors prize. Importantly this sapphire has received no enhancement, a detail that significantly elevates its desirability among informed buyers who value untreated material. At The Natural Sapphire Company we prioritize transparency about origin, treatment, and grading, and this sapphire combines an attractive carat weight with the polish and cut quality to perform beautifully once set.

The inclusions in this sapphire are subtle, yet they give the gem an unmistakable signature that confirms its natural formation and helps differentiate it from treated or synthetic material. Under magnification you will notice fine, isolated needle like and pinpoint mineral inclusions, along with delicate growth related features often described as fingerprint patterns or veil like planes, and these internal traits are distributed in a way that is consistent with Australian corundum. Rather than detracting from the gem, these tiny natural features contribute to its character, producing micro reflections and internal sparkle that change with movement, and they also provide a reliable internal map that gemologists can reference when verifying provenance. Because the stone is unheated, these inclusions remain intact and unaltered, offering an honest representation of the gem as it formed deep in a geological environment rich in the trace elements that influence color.

From an optical and gemological perspective this sapphire demonstrates why color, cut, and clarity must be considered together. The intense bluish green hue is the result of a balance in trace elements such as iron and titanium, and in some instances low concentrations of chromium can subtly influence tone, producing the unique green leaning blue that has become a hallmark of certain Australian sapphires. The mixed brilliant cut has been executed to enhance life and scintillation, combining a faceting arrangement that returns light efficiently and reveals a lively mix of flash and depth, while the fancy shape provides an original silhouette well suited for bespoke engagement rings or confident statement pieces. At 1.57 carats the stone is large enough to command presence, yet compact enough to be versatile in design, and its excellent polish ensures clean facet junctions and unobstructed light performance.

For the educated buyer seeking both aesthetic beauty and long term value this Australian sapphire represents a compelling choice. Natural, unenhanced sapphires with intense color and very slight inclusions are scarce relative to heat treated or otherwise enhanced material, and the combination of origin, clarity grading, and cut quality supports both wearable elegance and collectible appeal. Sapphires are rated nine on the Mohs scale, making them exceptionally durable for everyday wear, and the stone will respond well to secure bezel or prong settings that showcase its distinct triangular inspired silhouette. At The Natural Sapphire Company we can provide further documentation and high resolution imagery to assist in design planning or valuation, and our gemologists are available to discuss the inclusion features and grading in greater detail, ensuring you acquire a piece whose natural signature and untreated status will be appreciated for generations.
