卖家的描述
Crafted with passion, we introduce this highly exclusive round-shaped aquamarine sphere. Aquamarine is cherished for its beautiful clear color and high market value. Set upon a solid wood base, this piece blends artisanal craftsmanship with natural aesthetics.
At Heart of Gemstone, we distinguish ourselves by offering only flawless gemstones. This piece has been meticulously inspected to ensure it is completely free of imperfections before being presented in the auctions.
What further sets us apart is the addition of an ALGT certificate, provided by an internationally renowned laboratory headquartered in Antwerp. ALGT is globally recognized for its advanced technology and highly accurate analyses. The included certificate not only enhances the value of the item but also provides you with the assurance that you are receiving an authentic and high-quality piece, independently tested and verified by experienced gemologists.

ALGT Certificate Information:
Report Number: 620665408

Variety: Aquamarine
Shape: Round Bead, Polished
Measurements: 24.46 - 24.48 mm
Weight: 20.48 in grams (excluding wooden stand)
Color: Blue
Transparency: Translucent
Comments: This aquamarine has been treated by a process (the filling of open fractures or cavities) that increases its appearance or durability.

This treatment is reversible at any time. Weight and measurements are approximate.

Item Condition: Excellent
Value indication:
• Aquamarine (blue) - Round Bead, Polished (~20,48 g *15/g = €307,20)
