In short: the Gemstone Bead & Brass Cabinet Knob is a crystal cabinet knob from the Brass Essence range, 25 mm — best for smaller drawers, jewelry boxes, and vanities wanting a compact gemstone-toned accent.

Brass Essence Product Code: C-0028

The Gemstone Bead & Brass Cabinet Knob rounds a polished sphere in gemstone-like tones onto a brushed gold brass base, across four saturated colors — black, pink, green, and blue — at a compact 25mm diameter, the smallest sphere knob across the Brass Essence crystal collection.

The four colors read closer to individual gemstones than the softer pastel tones of the Natural Crystal Ball knob — black takes on an onyx-like depth, green a jade or malachite tone, blue a lapis character, and pink a rose quartz warmth — giving this knob a bolder, more jewelry-inspired palette within a smaller footprint.

The vendor specification for this design lists brass as the stated material despite the gemstone-toned colors, the same pattern seen on the C-0021 round knob elsewhere in this batch — we've written this listing around the confirmed color and finish facts while flagging the material for verification against the physical product.

Because the sphere is smaller than the range's other stone and crystal knobs — 25mm against the more common 30mm — it suits narrower drawer fronts or spaces where a full-size crystal knob would feel oversized, without losing the jewel-toned color statement.

The brushed gold base gives each bead a defined edge and carries the fixing screw, and the four colors make this knob a practical way to color-code smaller drawers, such as a jewellery box or a compact vanity unit, in tones with real gemstone character.

What is the Gemstone Bead & Brass Cabinet Knob?

The Gemstone Bead & Brass Cabinet Knob is a crystal cabinet knob from the Brass Essence range. According to mineralogical reference data on quartz, quartz defines the value of 7 on the Mohs hardness scale, the reference point mineralogists use for that grade of hardness, which is part of why cut crystal and quartz-based pieces hold a polish so well over years of handling, which is part of why crystal is a genuinely practical choice for hardware that gets handled daily, not just a decorative one.

Is this genuine gemstone, or a gemstone-effect finish?

The vendor specification lists brass as the material despite the gemstone-like colors and finish — we'd recommend confirming with our team whether this uses genuine stone or a stone-effect coating before placing a large order.

How does the 25mm size compare to the Natural Crystal Ball knob?

This knob is smaller, at 25mm against the Natural Crystal Ball's 30mm, and uses a bolder, more saturated four-color palette closer to individual gemstones, rather than the softer natural stone tones of the larger knob.

Which color works best for a small jewellery drawer?

All four work well in that setting — black gives a deep, formal look, pink and green offer softer or fresher accents, and blue provides a cooler contrast, so the choice comes down to the room's existing palette.
