In short: the Natural Stone & Brass Round Knob is a crystal cabinet knob from the Brass Essence range, 30 mm — best for kitchens, wardrobes, and vanities wanting a stone-look sphere knob in a choice of colour.

Brass essence Product Code: C-0021

The Natural Stone & Brass Round Knob sets a polished stone sphere on a brushed gold brass base, across the widest colour range of any single-size knob in the Brass Essence crystal collection — green, white, pink, and purple — all at a consistent 30mm diameter.

Each colourway draws on a different natural mineral tone, giving this knob the same kind of genuine material variation found on the Natural Crystal Ball knob elsewhere in the range, rather than one material dyed to four different shades — part of what separates natural stone hardware from a uniformly manufactured alternative.

The stone is polished to a smooth, rounded finish rather than cut into faceted planes, giving a soft, tactile grip and a gentle, diffused light reflection — closer in handling feel to the Natural Crystal Ball knob than to the sharply faceted artificial crystal pieces elsewhere in Brass Essence.

Because the underlying material here reads as natural stone by colour and finish, but the vendor specification for this particular design lists brass as the stated material, we've written this listing around the confirmed facts — a polished stone-look sphere on a brass base — while flagging the specification gap for verification against the physical product before large orders.

As with any natural or natural-look stone piece, expect gentle variation in tone and finish within each colourway — no two knobs will be perfectly identical, since the material isn't moulded to a single repeating pattern.

The four colours make this knob a practical choice for colour-coding cabinetry, or simply picking the one tone that best complements an existing kitchen, wardrobe, or vanity scheme, all sharing the same smooth sphere shape and brushed gold base.

What is the Natural Stone & Brass Round Knob?

The Natural Stone & Brass Round 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 knob genuine natural stone, or does it just look like stone?

The vendor specification for this design lists brass as the material despite the stone-like colours and finish — we'd recommend confirming with our team whether this is genuine natural stone or a stone-effect finish before placing a large order.

How does this compare to the Natural Crystal Ball & Brass Cabinet Knob?

Both are polished spheres on a brushed gold brass base at a similar 30mm size, but this knob offers a different four-colour range — green, white, pink, purple — compared to the Natural Crystal Ball knob's jade, marble white, rose pink, and lapis blue options.

Can I mix multiple colours across the same set of drawers?

Yes, all four colourways share the same size and shape, so assigning a different colour per drawer is straightforward for colour-coded storage or simply personal preference.
