The Mother of Pearl & Brass Round Cabinet Knob inlays a natural mother-of-pearl shell face onto a brushed gold brass base, across three sizes — 27mm, 32mm, and 37mm — bringing a genuinely different material into the brass collection, since the visible face is shell rather than metal, stone, or ceramic.

Mother-of-pearl carries a natural iridescent sheen that shifts subtly between white, pale pink, and soft blue-grey depending on the angle of light — a quality unique to genuine shell material that no painted or printed surface can fully replicate, which is why this knob reads as noticeably more luminous than a plain white ceramic or acrylic alternative.

Because the shell is a natural material, expect gentle variation in the exact pattern and iridescent shift from knob to knob — part of what makes mother-of-pearl hardware feel considered rather than mass-produced, similar to how natural marble or crystal pieces elsewhere in Brass Essence carry their own individual character.

The three sizes cover a useful range for a single kitchen or wardrobe project: 27mm for smaller drawers, 32mm as a versatile mid-size, and 37mm for cabinet doors wanting a larger, more prominent shell face — all sharing the same brushed gold base and iridescent shell tone.

Clean with a soft, barely damp cloth rather than soaking the shell, since prolonged water exposure isn't ideal for natural shell material — the same care given to genuine mother-of-pearl jewellery or decorative pieces.

• 27mm size: smaller drawer fronts
• 32mm size: versatile mid-size for most cabinetry
• 37mm size: cabinet doors wanting a larger shell face

Is the iridescent shine on this knob real mother-of-pearl or a printed effect?

Genuine natural mother-of-pearl shell — the subtle colour shift you see under different light is a real optical property of the shell material, not a printed or coated finish.

How do I clean a mother-of-pearl knob without damaging the shell?

Use a soft, barely damp cloth rather than soaking it, the same care you'd give any natural shell or pearl item — avoid harsh cleaning chemicals or prolonged water exposure.

Which of the three sizes is most versatile for a mixed kitchen project?

32mm tends to work well across the widest range of drawer and door sizes, while 27mm suits smaller drawers specifically and 37mm gives a more prominent shell face on larger cabinet doors.
