6.30 Ct. Apatite from Brazil

One beautiful transparent 6.30 carat oval shape greenish blue apatite from Brazil, measures 13.35 x 10.64 x 6.67 mm, and has a mixed brilliant cut. This gem from The Natural Gemstone Company presents a very light color intensity coupled with very very slightly included clarity when evaluated at eye level, and an excellent polish. Importantly, this stone has received no enhancement, so the color and clarity are wholly natural. The combination of substantial carat weight, an elegant oval outline, and an eye clean appearance gives this apatite a presence and rarity that is difficult to find in untreated material. For collectors and connoisseurs seeking a statement gem that is both natural and showy, this piece stands apart from many alternatives on the market that are either smaller, more heavily included, or routinely heat treated or otherwise enhanced.

The exceptional sparkle of this apatite begins with its intrinsic crystal structure and continues through the precision of the mixed brilliant cut. Apatite forms in a hexagonal crystal lattice which interacts with light in a way that produces bright flashes and a lively internal life when the material is transparent and clean. The cutter has chosen a mixed brilliant design to exploit that behavior, combining a faceted crown that directs light into the table and crown facets for scintillation, with a cleverly proportioned pavilion that returns light through the crown rather than leaking it from the base. Because the stone is very transparent and very very slightly included at eye level, light is able to travel unimpeded across multiple facet junctions and then refract and reflect in a dynamic way. The excellent polish enhances each facet plane so that reflections are crisp and the transitions between light and dark are dramatic. The result is a type of sparkle that is especially lively in motion, with quick scintillation and lively flashes of greenish blue that change with viewing angle, a performance that rivals stones with higher refractive index when those stones are compromised by cloudiness or surface wear.

When compared to other popular green blue gemstones on the market, this apatite offers a combination of attributes that favors uniqueness and value. Aquamarine of similar hue is often prized for its crystalline coolness, but it is frequently cut in step shapes that emphasize calm color rather than lively sparkle. Large aquamarines that are untreated and eye clean command high prices and can lack the vivacity that a mixed brilliant cut apatite brings to the table. Blue topaz can show strong sparkle but is commonly irradiated and heat treated to achieve its hue and is more abundant, making it less rare. Tourmaline and tanzanite offer wonderful saturation and depth, but they are commonly more costly per carat when they reach larger sizes that are eye clean and untreated. This 6.30 carat Brazilian apatite is rare in the raw, and its untreated status and excellent polish give it exceptional value for someone who wants an eye catching, natural gem. It is also worth noting that apatite sits at a different hardness than many other gems, so wear considerations are practical advice rather than a detriment to desirability. A well designed setting will protect the stone and allow its unmatched sparkle to be enjoyed daily.

Choosing a gemstone is about balancing beauty, durability, rarity, and authenticity, and this greenish blue apatite from The Natural Gemstone Company scores highly across those criteria for customers who prioritize natural character and optical performance. The stone is a vivid example of how natural crystal structure and expert cutting combine to create scintillation and life that catch the eye and hold attention. Because there is no enhancement, you are acquiring a gemstone whose color and clarity are the direct result of geological processes in Brazil rather than human alteration, and that truth matters to collectors and jewelers alike. For a bespoke setting, we recommend designs that both showcase the oval silhouette and offer protective elements for everyday wear. If you would like, our team can advise on ideal mounting styles to maximize the display of light across the crown and to protect the girdle and shoulders. At The Natural Gemstone Company we stand behind the provenance and description of this piece, and we welcome inquiries for more images, viewing options, or custom design consultations so that this exceptional 6.30 carat apatite can become a centerpiece of your collection or a one of a kind commission.
