7.02 Ct. Bi Color / Parti Sapphire from Madagascar

The Natural Sapphire Company presents a rare Blue Green 7.02 carat bi color parti sapphire, C.Dunaigre certified, originating from Madagascar, heat treated to enhance its natural character. Cut as a classic emerald shape with precise faceting, this stone measures 13.40 by 9.30 by 6.07 millimeters, and displays a vivid color intensity with a clarity graded as very slightly included when evaluated at eye level, and an excellent polish. The geometric faceting of the emerald cut lends the stone a composed architecture, a disciplined arrangement of step facets that form elongated, parallel planes across the crown and pavilion. These planes are not random, they are placed with careful intention to create broad reflective windows that allow light to travel within the gem, to pause and gather color, then to release it as deep flashes of blue green and bright flashes of yellow green as the stone or the observer moves. The relationship between the table, the shoulders, and the stepped pavilion produces a hall of mirrors effect, an optical depth that feels like looking into a jewel of architectonic complexity. With each facet precisely angled, light entering the crown is guided into the heart of the sapphire, where the stone s bi color character reveals itself in layered planes of hue. Where the blue and green meet, you will observe a distinct parti boundary that shifts depending on the light source and viewing angle, a dynamic interplay born of both rough crystal zoning and the cutter s skill. Because the cutter allowed for generous tables and long steps, this sapphire benefits from both strong color saturation and a modern sense of open clarity, resulting in flashes of scintillation along the facet edges and broad flashes of color across the surface. The overall effect is not only bright and lively, but also controlled and architectural, a gemstone that displays its light play like a finely tuned instrument.

This particular 7.02 carat emerald cut sapphire is not a mass produced commodity, it is a singular offering that speaks to collectors and connoisseurs who prize provenance and personality above mere size. Certified by C.Dunaigre, its lab color classification is Blue Green, a hue that is at once familiar and elusive because it lives between two beloved color worlds. The Natural Sapphire Company has curated this gem with the same discretion it applies to its most exclusive parcels, and we present it as a bespoke choice for someone who wishes to own a piece that will not be replicated. The cutting profile was chosen to maximize the stone s innate bi color drama, to preserve color zoning rather than force homogenization, and to balance visual weight with wearability. In the right setting this sapphire will read as deep forest green in one viewing, as luminous teal in another, and as an intense blue green with flashes of chartreuse in direct light. That unpredictability grants ownership a feeling of discovery each time the gem is seen, an intimate secret between the wearer and the gem. Owning this sapphire places you in an exclusive circle, because gems of this calibre and character are extremely rare from Madagascar in this size and cut. Each facet was aligned to amplify the stone s internal architecture, and the clarity grade of very slightly included at eye level ensures the visual experience remains clean and vibrant without sterilizing the natural features that give this gem its identity. The excellent polish contributes to crisp facet junctions and mirror like surfaces that intensify the light play, while the heat treatment has been applied with restraint and transparency to stabilize color and enhance clarity. The Natural Sapphire Company offers the full C.Dunaigre report so that provenance, treatments, and precise measurements are documented for posterity. For collectors, jewelers, and patrons who commission custom work, this stone represents a rare inventory opportunity to build a one of one jewel.

Imagine this emerald cut sapphire set within a refined, custom mounting, its long table echoing the lines of an architectural band, its step facets catching candlelight and city glare with equal aplomb. A low profile bezel will emphasize color, a delicate prong setting will increase light circulation and present more scintillation, and a bespoke halo in warm metals will pick up the yellow green flashes for evening wear. Our gem specialists at The Natural Sapphire Company can advise on settings that preserve sightlines to the parti transition, and recommend proportions that protect the stone while showcasing its geometry. This is not a stone to be hidden, it is a stone to be revealed in moments that matter, to be handed down as a defining object in a family s collection, to be photographed and remarked upon because its color story refuses to be ordinary. Because only a very limited number of stones demonstrate this combination of size, vivid color, clarity, and architectural faceting, this offering is deliberately exclusive. We limit the availability of such gems in order to preserve their special status, and to offer clients the confidence that when they acquire a gem from The Natural Sapphire Company they are joining an elite group of caretakers of extraordinary natural beauty. The C.Dunaigre certificate accompanies the stone, and our team stands ready to discuss bespoke mounting options, secure shipping, and long term care.

The gem s scale at thirteen point four zero by nine point three zero by six point zero seven millimeters provides a commanding presence on the finger without overwhelming, offering an ideal balance for both solitaire and more elaborate compositions.
