Our Amethysts
At GEMNAT, each amethyst is 100% natural and sourced from ethical mines in Brazil and Zambia. Our in-house gem expert hand-selects every stone for its deep violet saturation, eye-clean clarity, and balanced proportions, ensuring every piece meets our AAA quality standards.
Amethyst has been cherished since antiquity for its calming energy and regal color. It symbolizes balance, serenity, and inner strength, making it a meaningful choice for everyday wear or special moments. Its rich purple hue pairs beautifully with all gold tones, from classic yellow to modern rose and white gold.
With decades of expertise as gemstone dealers, GEMNAT ensures each amethyst is thoughtfully matched with a setting that enhances its natural beauty and brilliance.
Amethyst is the birthstone of February and traditionally gifted for the 6th wedding anniversary, offering both significance and timeless elegance.
