The world of fine jewellery is constantly evolving, and 2025 is set to be a year defined by bold colour, subtle elegance, and a renewed appreciation for exceptional craftsmanship. Fresh from my time at the Tucson Gem Show, I have spotted some emerging trends set to add excitement to your jewellery box.
1. The Neon Glow of Mahenge Spinel
If there’s one gemstone everyone was searching for, it was Mahenge spinel. These stunning gems, especially the hot pink and vibrant fuchsia hues, were the undisputed stars of the show. Their incredible, almost-neon glow is something a camera simply can’t capture-you have to see it in person to truly appreciate the electric, luminous quality.
A well-cut Mahenge spinel makes for an unforgettable statement piece, whether it's a unique east-west set ring or a delicate pendant. While they can be a significant investment, their increasing popularity and rarity make them a top choice for gemstone collectors and discerning jewellery lovers alike.
2. The Rise of Unheated Tanzanite
Forget the traditional royal purple tanzanite you know. The next big thing is the unheated material, which boasts a captivating blend of purplish-blue and grey tones. This sophisticated, muted palette feels incredibly fresh and is a perfect match for lovers of gemstones with their own fingerprint (I see you!).
Unheated tanzanite is a testament to natural beauty and a move towards showcasing gemstones in their most authentic form. Its crisp, lively colour offers a new take on a classic stone, making it a valuable addition to any collection of fine jewellery.
3. Minty & Seafoam Tones
The "seafoam" and "minty" colour trend is here to stay. While these fresh, green hues were spotted in various stones, the most in-demand were garnets and tourmaline. Demantoid and particularly tsavorite garnets were selling out fast at the show, proving their enduring popularity. These gems are a favourite of gemstone enthusiasts and jewellery designers for a reason. Their vibrant, lively colour is simply stunning.
A fascinating fact for any gem nerd: garnets are typically inert under UV light (meaning they do not fluoresce). However, many mint hued meralani garnets often change from green to pink under UV light, adding another layer of intrigue to their already impressive appeal. Look for these gorgeous green gemstones in modern settings or as a pop of colour in bespoke jewellery designs.
4. A Celebration of the Lapidary Artist
Beyond colour, the most significant trend I noticed was the booming appreciation for gemstone cutting. We are all becoming more skilled at spotting a truly well-cut stone, and in 2025, that quality is non-negotiable. The difference between a beautifully faceted gem and a poorly cut one is immense, and consumers are increasingly willing to pay a premium for that precision and brilliance. Bravo.
This growing appreciation for the art of the lapidary is leading to a surge in demand for fancy cuts and fantasy cuts. The creative and intricate work of artists like John Dyer, to those cutting unique "egg" cuts, to Glenn Preus and his endlessly romantic old world cutting style, how gems are cut is gaining widespread recognition. This trend isn't just about owning a beautiful piece; it’s about celebrating the artistry and skill that brings a rough stone to life. Expect to see more unique, imaginative cuts in high-end jewellery and custom pieces.
Bonus Trends: Lavender and Sapphire's Reign
A special mention goes to the lavender gemstone trend. Spinels and sapphires in this soft, elegant shade were a major hit. And, of course, no trend report would be complete without a nod to the timeless blue sapphire. The king of gemstones continues to hold its throne, proving that while new trends emerge, a classic never goes out of style.
And for the answer to the gem nerd question: What do Mahenge spinels, unheated tanzanites, and tsavorites have in common? They are all unheated and untreated natural gemstones which is a clear sign that authenticity and raw, natural beauty are the most coveted qualities in the jewellery world right now.
