Impimo Moissanite & Black Onyx Geometric Ring (925 Sterling Silver)
Bold. Black. Brilliant.
A striking geometric statement ring, crafted with genuine black onyx framed by brilliant moissanite. The deep jet-black onyx creates a dramatic contrast against white moissanite fire — a modern-classic piece that turns heads, from boardroom to evening wear.
แหวนดีไซน์เรขาคณิตโดดเด่น ประดับหินโอนิกซ์ดำแท้ในกรอบโมอีสที่เปล่งประกาย สีดำสนิทของโอนิกซ์ตัดกับแสงสีขาวสว่างของโมอีสอย่างคมชัด ให้ลุคโมเดิร์นคลาสสิกที่โดดเด่นทุกครั้งที่สวมใส่
Why This Piece?
- Genuine Black Onyx: Natural jet-black onyx — each piece hand-selected, specially cut, and individually polished to fit the geometric frame. Deep, uniform colour, no two are exactly alike.
- D Color VVS1 Moissanite: Lab-created silicon carbide — Mohs 9.25, brilliance 2.65 RI. Rivals the fire of natural diamond at a fraction of the price.
- Geometric Rhombus Design: A modern-classic silhouette with a substantial, durable band — crafted for everyday wear and easy stacking.
- 925 Sterling Silver with 18K White Gold Plating: Hypoallergenic, tarnish-resistant, built for daily wear. S925 stamped.
- Arrives Gift-Ready: Presented in our signature Impimo luxury box with quality guarantee included.
แหวนเรขาคณิตชิ้นนี้คือเครื่องประดับที่ตอบโจทย์ทุกวัน หรูหรา โดดเด่น และเป็นของขวัญสุดพิเศษสำหรับคนสำคัญ
