Birthstone questions

Everything you need to know about birthstone jewelry.

The January birthstone is garnet — a deep red gemstone symbolising love, friendship and trust. At Sagacia, January birthstone jewelry features genuine natural garnet in 925 sterling silver.
The February birthstone is amethyst — a violet variety of quartz ranging from pale lilac to deep purple. One of the most loved gemstones in the world. At Sagacia, February birthstone jewelry features genuine natural amethyst in rhodium vermeil over 925 sterling silver.
The June birthstone is moonstone — an iridescent feldspar with a distinctive glowing shimmer called adularescence. Moonstone is one of our most popular gemstones and one of the most beautiful in natural light. At Sagacia, June birthstone jewelry features genuine natural moonstone in 925 sterling silver.
At Sagacia, we use tanzanite as our December birthstone — a rare blue-violet zoisite found only near Mount Kilimanjaro in Tanzania. One of the rarest gemstones in the world and a genuinely special gift for December birthdays.
