The 18K Superiority
Why we choose AU750 over 14K or 9K
Richer Golden Glow
18K gold contains a higher percentage of pure gold, resulting in a deeper, more vibrant yellow hue that 14K or 9K simply cannot match.
Vs. The Pale Look of 14KHypoallergenic Purity
With less base-metal alloys, 18K gold is far less likely to cause skin reactions, making it the safest choice for 24/7 wear on sensitive skin.
Vs. The Nickel Risks in 9KEternal Luster
18K gold is highly resistant to tarnish and oxidation. It maintains its prestige and financial value, truly becoming a legacy piece.
Vs. The Tarnishing of Low-Karat GoldQuick Fact: 18K Gold (AU750) is 75% Pure Gold, while 14K is 58.3% and 9K is only 37.5%.
10mm Imperial Tahitian Pendant
Mysterious, bold, and sophisticated. Sourced from the turquoise lagoons of French Polynesia, this solitaire masterpiece captures the sun's rarest reflections within its deep, iridescent core.
The Depth of Nature
Tahitian pearls are globally unique for their natural dark body color. Unlike dyed black pearls, our 10-10.5mm specimens exhibit a natural metallic orient—shifting between peacock green, silver, and deep charcoal with every movement.
"A symbol of wisdom and inner strength, it is a gem that carries the secrets of the deep sea."
