1.02 Ct. Blue Sapphire from Tanzania

This specimen is a transparent 1.02 carat asscher octagon shape blue sapphire, presented in a faceted cutting style with asscher cut geometry, measurements 5.72 x 5.62 x 3.60 mm, clarity graded as slightly included at eye level, color intensity described as intense, and an excellent polish. The gem originates from Tanzania, and the stone has undergone a standard heat treatment to enhance color uniformity and stability. The asscher octagon shape offers a balanced, architectural silhouette that reads larger on the finger than many round counterparts of equivalent weight, while the faceting pattern produces broad, linear reflections that emphasize the deep blue hue and the stone transparency. In well lit, face up viewing the combination of intense color and the stepped facet arrangement yields a clear, saturated appearance with lively internal reflections and a clean, polished girdle and crown presentation.

The asscher cut is inherently precise in its facet delineation, and this example demonstrates disciplined cutting with symmetrical pavilion and crown relationships that preserve weight while optimizing visual presence. The near square outline with clipped corners creates an elegant octagonal profile, and the depth dimension of 3.60 mm has been managed to deliver controlled light return rather than an overly deep, dark tone. Facet junctions are finished to a high standard, contributing to the excellent polish grade and producing crisp, mirror like planes that direct color and light toward the viewer. For designers and lapidaries, this cutting geometry is versatile, lending itself to both solitaire oriented settings where the stone sits prominently, and to more complex halo or three stone arrangements where the asscher form complements angular metalwork.

Regarding clarity and treatment, the slightly included grade at eye level indicates the presence of minor internal features that do not significantly detract from the gem aesthetic, rather they provide natural character and confirm the natural origin. The applied heat treatment is a common and accepted enhancement within the trade, performed to improve tone and saturation in a stable manner that does not materially affect the structural integrity of the corundum. As a corundum species, sapphire rates high on the Mohs hardness scale and offers notable durability for daily wear, making it suitable for rings, pendants, and other jewelry that will be worn regularly. Proper mounting and routine care, including protection from sharp impacts and occasional professional cleaning, will preserve the stone appearance and polish over time.

For clients and collectors who value measured, enduring attributes over transient trends, this sapphire embodies the qualities that define long term value, including natural origin, professional enhancement transparency, and a cutting execution that respects the balance between carat weight and face up appeal.
