1.72 Ct. Blue Sapphire from Thailand

This pear shape blue sapphire is presented with full GIA certification, confirming authenticity and the reported gemological attributes. The stone weighs 1.72 carat, and measures 7.41 by 6.73 by 4.41 millimeters. It is transparent, faceted in a mixed brilliant cut that combines step and brilliant faceting principles to optimize both color and light return. Clarity is reported as very very slightly included, evaluated at eye level, which indicates minimal visible inclusions and a clean appearance to the unaided eye. The polish is excellent, ensuring smooth facet junctions and an even reflective surface, and the gem has been heat treated, a stable and commonly accepted enhancement used to improve color and clarity in corundum. The origin is Thailand, and the combination of certification, proportion, and finish makes this sapphire a technically refined and well documented example.

The color of this sapphire is a defining characteristic and a primary factor in its rarity. It is described with intense color intensity, a saturation level that yields strong, vivid blue without becoming overly dark or opaque. In the marketplace many blue sapphires of this size demonstrate either lighter tones or uneven distribution of color, and larger stones with similarly strong saturation and transparency are significantly less common. Finding a stone near two carats that maintains strong saturation across a well cut pear profile, while remaining transparent and free of eye visible inclusions, represents a constrained subset of available material. Compared to typical calibrated stones and smaller melee, this gem stands out for the depth and uniformity of its blue, making it a rare balanced combination of size, hue, and clarity.

The pear shape and mixed brilliant cut are chosen to enhance both the visual weight and light performance of this sapphire. The proportions given, with a modest table and a pavilion depth represented by the 4.41 millimeter measurement, support an attractive face up size while preserving internal brilliance. Mixed brilliant cuts often place a brilliant style faceting on the crown with step or facet work on the pavilion, creating scintillation and return through the table, and this approach is particularly effective in pear shapes where the tapered point and rounded shoulder must both contribute to overall symmetry and light dispersion. The excellent polish contributes to crisp facet reflections, and the very very slightly included clarity grade means that the stone will present as clean in typical wear, offering both sparkle and a solid, saturated color field.

Provenance and treatment are important considerations for collectors and those commissioning jewelry, and this sapphire benefits from clear documentation. The GIA certification provides independent verification of weight, measurements, cut description, clarity observations, color characteristics, and treatment status. Origin from Thailand is noted on the report, and Thai sapphires are often appreciated for their rich, classic blue tones. The heat treatment recorded for this gem is a standard practice in the industry, applied in a controlled way to enhance color and reduce unwanted inclusions, and it is considered stable for normal wear. For those comparing options, the documented origin and lab report reduce uncertainty and support informed decisions about valuation, setting, and long term care.

In practical terms this 1.72 carat pear shape sapphire is suitable for a range of jewelry uses, most notably as the central stone in engagement rings and pendants where the pear silhouette offers both elegance and a visually elongating profile. Its near two carat weight combined with intense color intensity will read larger on the finger than many stones of equivalent weight that have less saturation, and the mixed brilliant faceting will provide a lively presence under varied lighting conditions. Sapphires are a durable choice for everyday wear due to their hardness of nine on the Mohs scale, but routine care and periodic professional inspection of the mounting are recommended. The Natural Sapphire Company documents each gem clearly and can advise on complementary mounting styles and metal choices to maximize the stone proportions and color. For clients seeking a rare combination of size and rich blue saturation in a certified, well finished sapphire, this Thai origin pear represents a measured and verifiable choice.
