Happening next week! 🐚

This 5-hour course delves into the enchanting beauty of pearls—their subtle glow, timeless appeal, and natural mystique. As June’s birthstone and one of the ocean’s most treasured gifts, pearls offer a fascinating gateway into gemmology and jewellery artistry.

Designed for curious minds and jewellery enthusiasts alike, this course provides a relaxed, hands-on journey into the world of pearls. You’ll learn how to recognize, admire, and care for these graceful gems. You’ll use your jeweller’s loupe to observe the delicate surfaces and overtones that make every pearl singular.

Whether it’s the satiny sheen of cultured Akoya pearls, the exotic charm of Tahitians, or the organic character of freshwater varieties, you’ll explore how to evaluate and care for these natural wonders before investing in your own.

While not a prerequisite, this course provides an excellent foundation and compliment for those planning to take our Pearl Stringing course.
