■ THE STONE:
Timeless elegance showcasing rich verdant brilliance | Sophisticated 7.19 carats with vintage charm | Classic step cut creating hall-of-mirrors effect | Exceptional transparency and clarity | Refined emerald alternative with enduring style

■ ORIGIN & HISTORY:
Green tourmaline has adorned aristocracy for centuries, prized for stunning verdant hues rivaling emeralds.

Brazilian specimens from legendary Minas Gerais are celebrated worldwide for exceptional color saturation and outstanding transparency.

Known as the "Stone of Prosperity," opening the heart chakra to attract abundance, success, and emotional healing. Promotes vitality, compassion, gratitude, harmonious connection with nature's regenerative energies. Treasured worldwide by anyone seeking growth, prosperity, balanced abundance, and heart-centered living.

■ WHY THIS GREEN TOURMALINE STANDS OUT:
✓ Classic Step Cut - Timeless emerald-style faceting for vintage elegance
✓ Substantial Size - 7.19 cts perfect for statement jewelry
✓ Exceptional Clarity - Outstanding transparency with hall-of-mirrors effect
✓ Rich Green Color - Deep saturated emerald-like hue
✓ Smart Alternative - Emerald beauty with superior clarity and durability

Comments:
-----------
Tourmaline is commonly heated or irradiated to improve or change the color. Color authenticity is currently undeterminable (Per ICA standards; natural rich green enhances value).

Exceptional transparency with classic step-cut faceting showcasing rich green color and geometric brilliance—ideal for vintage-inspired engagement rings, Art Deco designs, or elegant pendants. With 7-7.5 hardness, green tourmaline offers excellent durability for everyday luxury wear.

Design Note: Step cuts (emerald cuts) are the hallmark of sophisticated jewelry design, favored for their elegant lines and ability to showcase a gemstone's exceptional clarity. This cutting style has adorned royalty and celebrities for centuries, offering timeless appeal that transcends trends.

Market Context: As fine emerald prices soar and availability decreases, discerning collectors recognize green tourmaline as the intelligent choice—offering emerald-rival beauty with superior clarity, better durability, and accessible luxury pricing.

Clarification on "See Comments" treatment disclosure:
------------------------------------------------------
When a certificate states "See Comments" under treatments, this indicates that laboratory testing could not conclusively determine whether the gemstone has been treated. This is standard for many gemstone types, including tourmaline and others, where distinguishing natural color from potential heating or irradiation is scientifically challenging with current gemological methods.

This does NOT mean the stone is treated; rather, it reflects the limitations of available testing technology. The comments section will explain the lab's findings in detail, and you should interpret this conservatively. We sell all such stones with full disclosure and at competitive prices reflecting current market standards.
