2.30 Ct. Greenish Blue Paraiba Tourmaline from Africa

One beautiful transparent 2.30 carat cushion shape greenish blue paraiba tourmaline with dimensions of 9.26 by 8.19 by 3.77 millimeters is presented, the cutting style is faceted with a mixed brilliant cut that balances large table facets for depth with smaller pavilion facets for scintillation, clarity is graded slightly included when evaluated at eye level indicating minimal internal features that do not detract from face up appeal, color intensity is medium which provides an elegant saturation that glows under natural light, polish is excellent and the surface finish is crisp and reflective, enhancement status is none and this stone is natural and untreated, origin of this paraiba tourmaline is Africa which produces paraiba type tourmalines noted for their vivid and often electric tones. The combination of a cushion outline and a mixed brilliant facet scheme yields a gem that reads larger than its carat weight, and the transparency and even color distribution allow the greenish blue hue to present consistently across the table. The dimensions of 9.26 by 8.19 by 3.77 millimeters place this gem in a size range that is ideal for signature rings, pendant centers, or investment pieces where both presence and wearability are required.

When assessing the gem from a grading perspective, there are several aspects that an educated buyer will want to weigh. Clarity described as slightly included at eye level means that under direct viewing there are minor inclusions which experienced cutters have positioned so they are minimally visible from the table, and these internal characteristics are typical of natural elbaite tourmaline and do not reduce durability. Medium color intensity is an attractive sweet spot for paraiba tourmaline because it offers vivid presence without becoming overly dark, allowing the stone to exhibit internal light movement and the characteristic neon aspect associated with copper bearing material. The fact that there is no enhancement is significant, because many colored gems on the market are heat treated or clarity enhanced, whereas this paraiba retains its original chemistry and color chain naturally, which preserves market desirability and collector value. African origins often yield paraiba tourmalines with stable color and good crystal quality, and the trace elements copper and manganese that create the greenish blue appearance are genuine geochemical signatures that separate paraiba tourmaline from more common blue green gems.

The optical performance of this paraiba tourmaline is a primary reason it stands out when compared to more common gemstones. Tourmaline has a refractive index in the range of about 1.624 to 1.644 which produces strong light return for a colored stone, and when combined with a mixed brilliant cut the result is both sparkle and internal fire. By comparison, aquamarine and emerald family stones have lower refractive indices around 1.57 to 1.58 which typically yields a softer, more tranquil luster, while blue sapphire has a higher refractive index around 1.76 which gives excellent brilliance but often lacks the neon luminosity that copper bearing tourmalines show. Diamond has the highest refractive index of common gemstones at about 2.42 producing unmatched brilliance, however diamonds display colorless white light dispersion rather than the vivid saturated glow that a paraiba tourmaline offers within its greenish blue palette. Paraiba tourmalines can also display pleochroism, showing slightly different tones when viewed from different angles, and this mixed color behavior contributes to a dynamic face up experience that many buyers describe as alive or electric. The medium color intensity in this example allows the greenish blue to transmit light in a way that appears luminous in daylight and incandescent light, making it more visibly striking than many aquamarines or pale sapphires of similar weight.

For an educated buyer considering both beauty and investment, this 2.30 carat African paraiba tourmaline offers several compelling attributes. The weight and dimensions are significant for a paraiba type stone, and the cushion shape is a classic silhouette that balances contemporary sparkle with timeless elegance. Slightly included clarity at eye level is acceptable and common for natural tourmaline, and in many cases these internal features serve as natural fingerprints that confirm origin and authenticity when viewed alongside detailed gemological documentation. The excellent polish and precise mixed brilliant facet arrangement enhance light performance which supports both aesthetic and market value. The fact that the gem is untreated, with no enhancements, is particularly meaningful for collectors who prefer natural material with verifiable provenance. At The Natural Gemstone Company we value transparency in grading and sourcing, and we provide stones with clear documentation and imagery so that buyers can make informed decisions. For setting, consider an open back or a partially open gallery to allow maximum light to enter and to show the greenish blue color fully. This paraiba tourmaline is equally suitable as a centerpiece for a bespoke engagement ring or as a collector grade specimen, and we are available to discuss mounting recommendations, certification options, and care instructions to ensure enduring beauty.
