4.79 Ct. Greenish Blue Paraiba Tourmaline from Mozambique

If you are searching for a single gemstone that can end your quest for the perfect engagement piece or the crown jewel of a collector s drawer, this greenish blue Paraiba tourmaline answers that need with authority. At 4.79 carats and measuring 10.51 by 8.76 by 7.56 millimeters, this cushion shaped tourmaline offers an ideal balance between presence and wearability, large enough to make a statement, yet refined enough to sit elegantly in a custom setting. The gem is transparent, faceted with a mixed brilliant cut, and finished with an excellent polish, qualities that matter when you want light and color to work together to create moments of true beauty. Sourced from Mozambique and heat treated to enhance its natural vibrancy, this stone displays an intense color intensity, a mesmerizing greenish blue that shifts with movement and light, and a clarity graded as very slightly included when viewed at eye level, a condition that preserves both durability and visual purity.

The way this piece is cut is central to its appeal, because the mixed brilliant cut has been chosen specifically to amplify the Paraiba s inherent optical strengths. The cushion outline provides broad facets on the crown which capture and collect light, while the brilliant facets on the pavilion return that light as lively scintillation and controlled flashes of color. This dual approach, combining larger table and crown facets with a series of smaller, well aligned pavilion facets, maximizes both brilliance and fire, producing an internal dance of aqua and teal that reads as vibrancy rather than scatter. The mixed brilliant style reduces the risk of windowing, so the interior of the gem remains visually active even under softer light, and the precise facet junctions created by an expert cutter increase the gem s overall symmetry and light return. The excellent polish is not merely cosmetic, it creates mirror like surfaces that allow light to glide over the stone and reflect with clarity, giving the tourmaline a lively, wet look that commands attention.

Color and clarity are the emotional core of any Paraiba, and this Mozambique example delivers on both, in harmony with its cut. The intense color intensity is a true greenish blue, a hue that sits between luminous turquoise and deep ocean teal, offering versatility for personal taste and jewelry design. Because the stone is transparent and very slightly included at eye level, the color reads evenly across the entire surface, with no distracting breaks or dark patches, and the inclusions that are present serve as minor fingerprints of a natural formation rather than flaws that interrupt beauty. Heat treatment has been applied to stabilize and enhance this intrinsic color, a common and accepted practice that brings out the vivid, neon like tones that Paraibas are celebrated for, while retaining the gem s natural structure and charm. At 4.79 carats, this gem offers a rare and collectible scale for a Paraiba, making it ideal for a spectacular solitaire ring, a pendant that centers a signature piece, or an exclusive collector s cabinet, and its cushion shape sits close to the finger for comfort while reflecting light from multiple directions.
