A Gem-Set for Grown-Ups What happens when LEGO turns its focus to minerals? You get the new Mineral Collection (21362) — a buildable, display-worthy set that bridges the worlds of geology, gemology, and design. For jewellery lovers, it’s unexpectedly delightful: a six-piece tribute to some of the world’s most beautiful crystals, made entirely of transparent, iridescent, and cleverly layered LEGO bricks.

This isn’t one for the kids’ toy box. Marketed as an “immersive creative challenge” for adults", the set has 880 pieces and retails at £54.99, making it one of the most accessible ways to indulge in a bit of desk-side sparkle — no loupe required.

From Facets to Bricks: A Jewellery Eye on LEGO Design

The collection features six minerals:

• Golden pyrite

• Purple amethyst

• Reddish-pink rhodochrosite

• Blue fluorite

• Green-pink watermelon tourmaline

• Vibrant tangerine quartz

What’s immediately clear is the level of thought that’s gone into mimicking each stone’s natural beauty using plastic blocks. The LEGO design team uses a mix of transparent, iridescent, and colour-tinted elements to simulate colour zoning, layering, reflectivity and crystal growth — the same details that make a gemstone come alive in jewellery.

In place of inclusions and birefringence, LEGO gives us translucent overlays, hidden studs and gradient stacking — a surprisingly elegant way to hint at the optical phenomena that jewellery lovers spend their lives appreciating.

From watermelon tourmaline to golden pyrite, LEGO’s Mineral Collection (21362) turns iconic crystals into colour-popping display pieces. Gem lovers, this one’s for you

Mineral by Mineral: What a Jeweller Might See

Amethyst: With its violet tones and pointed cluster structure, this one nods to the regal cabochons and faceted cuts found in antique and modern collections alike. The shape captures that raw, geode‑like appeal, softened by smooth stacking techniques.

Rhodochrosite: A sweet, rounded formation rendered in dusky pinks. The LEGO version hints at its banded beauty — a favourite of artisan jewellers and bead makers.

Pyrite: Known as Fool’s Gold, pyrite gets the metallic treatment here with shiny gold bricks in sharp cube formations. The faceting is exaggerated — but feels right for such a geometric mineral.

Watermelon Tourmaline: A favourite of gemstone collectors, this gem’s natural green‑to‑pink fade is captured using stacked transparent layers. LEGO swapped this in during development for stronger visual punch — and it’s a jewel-toned triumph.

Fluorite: With its calming blue tones and cubic geometry, fluorite gets a modernist treatment. This is one of the most sculptural builds — a clean-lined counterpoint to the more organic forms.

Tangerine Quartz: A burst of orange brilliance with slanted surfaces and a prism-like crown. This is colour therapy in block form.

For jewellery aficionados, it’s fun to see which stones feel recognisable and which take artistic licence — but that’s part of the charm. This is mineral mimicry, not mineralogy.

Design Choices: Colour Play, Contrast, and Crystalline Cues

According to LEGO, one of the biggest design challenges was colour balance. Some minerals — like black tourmaline — had to be dropped for visibility issues, while others were chosen to add vibrancy when viewed together on display. Watermelon tourmaline replaced its black cousin for exactly this reason.

In the end, it’s a considered curation of shape, colour and structure — a kind of block-built homage to the jewellery design process, where contrast, symmetry and optical delight reign supreme.

The pieces sit on individual black stands, allowing each mineral to be admired like a miniature specimen or a museum-style design prototype. It’s easy to imagine these displayed in a gem setter’s workshop or a boutique gallery window.

Why Jewellery Lovers Will Love It

Design-minded: The LEGO set uses colour theory, geometric forms and symmetry — key ingredients in jewellery design.

Collectible appeal: With a limit of 3 per household, LEGO is treating this like a small-run collector’s piece — a familiar concept for jewellery fans used to numbered editions.

Mindful making: Described by LEGO as a “creative challenge”, the build process mimics the meditative rhythm of wax carving, stone setting or beading — perfect for anyone who finds joy in hands-on detail.

Giftable and displayable: Unlike most toys, this set is designed for display. Whether it ends up on a studio shelf, gemology bench or coffee table, it will charm both jewellery professionals and design-conscious collectors.

Inspiration engine: The colour stacking, the angles, the modularity — there’s plenty here to spark ideas for real-world jewellery, especially for those who work in enamel, resin, or coloured stone layouts.

The Jewels Club Take

For lovers of gemstones, crystals, and the visual language of jewellery, LEGO’s Mineral Collection is more than just a novelty — it’s a design object, an artful conversation piece, and a welcome detour into colour, geometry and buildable beauty.

Whether you’re a bench jeweller, a gemstone collector, or simply someone who likes their obsessions with a side of play, this is one set you’ll want on your desk. Think of it as a miniature tribute to what makes jewellery so magical: colour, clarity, form — and a bit of fun.
