1.01 Ct. Bi Color Sapphire from Australia

This transparent 1.01 carat, emerald cut, bi color sapphire from Australia represents a precise balance of proportion and optical character, offered by The Natural Sapphire Company. The stone measures 6.72 x 5.42 x 2.79 mm, producing a length to width ratio of approximately 1.24 and a depth proportion near 46 percent, dimensions that reflect a deliberate cutter decision to preserve weight while optimizing face up color and pavilion light return. The cut is a classical emerald step configuration with broad table, well aligned crown steps, and a neatly faceted pavilion that produces linear flash and directional light play. Clarity is graded as very very slightly included evaluated at eye level, preserving a high degree of transparency, and the polish is excellent, with clean facet junctions and smooth facet planes that maximize brilliance and the integrity of the window through the table. Enhancement is limited to heat treated, a stable and widely accepted practice that improves color saturation without compromising structural durability.

Color is the defining technical attribute of this sapphire, exhibiting a distinct bi color presentation that ranges from a medium intense green to a cool medium intense blue depending on face up orientation and lighting. The step cut emphasizes color zoning and directional color shifts rather than scintillation, creating clear bands of hue that move across the table as the gem is tilted or as the lighting angle changes. This pleochroic behavior is characteristic of corundum chemistry and is made more expressive by the cutter who aligned pavilion facets to enhance dichroic separation, producing a pleasing juxtaposition of blue and green planes. The medium intense color intensity was achieved and stabilized by heat treated enhancement, which reduces brownish peripheral tones and consolidates the blue green axis without inducing artificial diffusion. Under magnification the very very slight inclusions are small and well positioned near facet junctions or in lower pavilion locations where they have minimal impact on light transmission, making the stone appear clean to the naked eye in typical viewing conditions.

Craftsmanship considerations are apparent in both the faceting design and the finishing quality. The emerald step cut requires disciplined symmetry and precise facet proportions to maintain even banding and to avoid a dominant window effect, and this sapphire demonstrates careful balance between table size and crown step height to sustain both color saturation and internal reflection. Corner facets are subtly truncated to soften potential stress points while preserving the stone footprint for bezel or claw mounting options. At 1.01 carat and with the dimensions specified, the stone sits as a versatile center gem for refined solitaire rings, low profile bezel pendants, or architecturally inspired east west ring designs, and it adapts equally well to complemented settings with melee diamonds or colored gemstone accents. The combination of excellent polish and stable heat treatment confers practical durability for everyday wear, benefiting from sapphire s natural hardness and resistance to abrasion, while the step facets provide understated elegance in formal contexts.

In application this Australian bi color sapphire translates to exceptional versatility, moving seamlessly between casual and formal environments. In relaxed daylight or casual attire the bi color effect reads as an intriguing green to blue flash that pairs beautifully with warm or cool metals, and in evening or formal lighting the medium intense tones deepen and present as a sophisticated, contemplative center stone. For bespoke clients The Natural Sapphire Company recommends considering metal color choices such as 18 karat yellow gold to enhance the green axis, or platinum and white gold to emphasize the blue component, and suggests modest accent pavage to preserve the linear step motif. We provide precise documentation on origin, enhancement, and the gem s measurements and clarity observations, and invite inquiries for custom mounting and design consultation to realize the optimal setting for this technically refined and visually compelling sapphire.
