Core Gemstone & Quality Details

Main Stone: 8.37-carat natural Paraiba tourmaline (central focal point, sourced from Brazil’s Minas Gerais—globally recognized as the premium origin for Paraiba tourmaline, with this carat weight being a scarce find in natural deposits)
Cut: Pear Brilliant Cut (teardrop silhouette with rounded end and tapered point, 58 precision-cut facets that maximize light reflection, amplifying the Paraiba’s inherent neon fluorescence and three-dimensional fire)
Color: Neon Blue-Green (uniform high-saturation tone, characteristic of top-tier Paraiba tourmaline, caused by copper and manganese trace elements, free from gray or brown undertones)
Clarity: VS1 Clarity (very slightly included, with minimal internal characteristics invisible to the naked eye; only detectable under 10x magnification, ensuring the gem’s translucent purity)
Accent Details: Lab-grown diamonds (symmetrically set on the ring shoulders and along the band’s edge, forming a delicate halo that highlights the pink tourmaline’s tender hue)
Accent Stone Quality: D-F Color (colorless to near-colorless), VS1 Clarity (eye-clean), Excellent Cut (optimal light performance to complement the tourmaline’s soft warmth without overwhelming it)
Overall Quality: Main stone natural (Brazilian origin, no heat treatment or dyeing—certified as “untreated”); accent diamonds lab-grown (conflict-free, eco-friendly, with quality parameters matching the main stone’s premium grade)
Setting Material: 18K White Gold (polished finish, 75% gold content ensuring superior ductility and scratch resistance; cool metallic luster creates a complementary contrast, enhancing the Paraiba’s neon hue saturation)

Design & Craftsmanship

Pear-Shaped Custom Claw Setting: 18K white gold prongs are tailor-made for the pear silhouette—5 reinforced prongs (1 at the tapered point, 4 at the rounded end) securely clasp the 8.37-carat Paraiba, avoiding facet coverage. Prong surfaces are micro-polished, with laser-engraved anti-slip textures to ensure long-term stability.
Structured Solid Band: The 18K white gold band maintains a 2.2mm uniform width from setting to shank, with a high-gloss polished surface that mirrors the Paraiba’s glow. The minimalist structure ensures the main stone remains the visual core, conforming to high-jewelry design principles.
Load-Bearing Ergonomic Design: The band junction is reinforced with a hidden arc structure to support the 8.37-carat main stone’s weight. The inner wall is precision-machined into a semi-circular arc, fitting the finger’s physiological curve and ensuring comfort during extended wear.

Wearing & Versatility

The 8.37-carat pear-shaped natural Paraiba tourmaline represents the pinnacle of colored gemstone value—its teardrop silhouette balances elegance and dynamism, while the neon blue-green hue exhibits strong light-gathering properties, remaining vivid under both natural and artificial light. The D-F color, VS1 clarity lab-grown diamonds form a subtle halo, avoiding overpowering the Paraiba’s unique charm, while the 18K white gold setting provides physical protection and tonal enhancement. As a natural gemstone with scarce carat weight and certified origin, this ring meets both high-end wearing and investment collection needs, suitable for important occasions such as red-carpet events and private auctions.
