5.13 Ct. Bluish Green Cabochon Turquoise from Persia(Iran)

If you have been searching for a naturally beautiful turquoise that finishes a design or completes a collection, this Persian turquoise from The Natural Gemstone Company answers that search with assurance and elegance. This one of a kind stone is a 5.13 carat, oval shape cabochon with exact dimensions of 12.10 x 9.91 x 5.89 mm, and it arrives to you exactly as nature formed it, no enhancement. The bluish green hue and medium color intensity make it versatile for designers who want a vivid presence without overwhelming a piece. The cabochon cutting style and excellent polish create a smooth, satiny dome that reads as both classic and contemporary, ideal for someone seeking an engagement ring alternative, a statement cocktail ring, or an heirloom quality stone for a trusted collection. Sourced from Persia, Iran, this turquoise carries the storied provenance and discerning appeal that collectors and custom jewelers appreciate, and The Natural Gemstone Company brings it to you with careful representation and full honesty about its untreated nature.

Look at this stone in daylight and you will see why turquoise has been cherished for centuries, the bluish green tone settles into a calm, sea glass like depth, the medium intensity allowing subtle shifts rather than stark flatness. In bright outdoor light, the color reads more saturated and luminous, the dome reflecting a soft sheen that highlights the polish and brings out any gentle variations in matrix or tone. In diffused daylight, such as a softly overcast day or an indoor room with north facing windows, the stone adopts a serene, pale turquoise presence that complements both warm and cool metals. The cabochon profile is especially flattering for this kind of color, because the curved surface concentrates the light into a gentle, even glow, making the color look richer at the crown while the lower portion appears more tranquil, giving a sense of layered color that changes with your movement.

Under artificial lights the personality of this Persian turquoise becomes even more engaging, with distinct shifts that will delight anyone who wears it. Under warm incandescent or warm LED lighting, the bluish green leans slightly toward a greener, more verdant tone, which pairs beautifully with yellow gold and rose gold settings and enhances a feeling of vintage warmth. Under cool fluorescent or cool LED lighting, the stone reads a touch bluer, crisp and modern, marrying particularly well with white gold and platinum for a contemporary look. In focused jewelry display lighting or small spotlights the excellent polish will create clean, round highlights on the dome, a high sheen rather than sparkle, because turquoise is opaque and its beauty is in surface luster and color depth, not faceted brilliance. In candlelight the effect is intimate, soft and almost painterly, the stone calming the light and returning a muted, soulful glow that makes it especially appealing for evening wear.

For the buyer who wants to finish a design with confidence, this turquoise is a natural solution, ready to be set and shown. The medium color intensity allows the stone to stand on its own as a center without overpowering complementary side stones or metalwork, and the oval cabochon shape adapts easily to bezel settings that protect the girdle and edges, or to secure prong mounts for a more open look. Persian turquoise is prized for its historical significance and stable beauty, and because this piece is untreated, collectors will value its authenticity and originality. Consider pairing it with warm yellow gold or with sterling silver for a classic southwestern aesthetic, or set it in platinum with subtle diamond accents for a modern heirloom. If you are designing an engagement ring for someone seeking uniqueness and meaning, the smooth, comforting surface of this cabochon offers a tactile intimacy that a faceted stone cannot provide.

Caring for this natural cabochon is straightforward, and The Natural Gemstone Company stands behind your purchase with guidance and support. Because it is untreated and naturally formed, you should avoid prolonged exposure to harsh chemicals, strong acids, and household cleaners, and remove jewelry before heavy work or swimming in chlorinated pools. Clean gently with warm soapy water and a soft cloth, never use ultrasonic cleaners or steamers on porous turquoise, and store it separately to prevent abrasion. If you desire additional protection for an everyday ring, ask about bezel settings or protective mountings, which both shield the stone and preserve its polished dome. When you receive this 5.13 carat Persian turquoise, you are receiving a ready made solution to the search for beauty that is both wearable and collectible, and The Natural Gemstone Company is here to help with setting advice, custom design consultations, and secure shipping, because we want your search to end with a stone that delights every time you see it.
