The Stone
See the natural beauty of Onyxa up close — the surface texture, colour depth, and veining that make this porcelain unique.
Colour:
Cream Beige Layered bands of honey, gold, and warm cream flow across this porcelain surface like sedimentary ribbons, recreating the rare beauty of natural onyx.
Onyxa is one of those surfaces that makes you pause and look again. Its warm cream base is swept with flowing bands of honey, tan, and golden-brown that layer over one another in sinuous curves, faithfully recreating the mesmerising stratified beauty of natural onyx — a stone so rare and fragile that it is almost never used for worktops. Caesarstone has captured that exotic beauty in porcelain, delivering a surface that can be installed as a kitchen island, a bathroom feature wall, or a dramatic fireplace surround without any of the translucency, fragility, or cost issues of genuine onyx. The Honed finish gives the banding a rich, tactile depth. And because it is porcelain, Onyxa delivers perfect scores across hardness, stain resistance, heat tolerance, and UV stability.

"Excellent Service and Beautiful Results - Highly Recommended! I recently had In2stone install new quartz worktops in my kitchen, and I couldn't be happier with the results. From start to finish, the experience was completely stress-free. The team was not only competitively priced but also incredibly friendly and professional throughout the entire process. They handled everything seamlessly - removing the existing sink, hob, and old laminate worktops before fitting the new quartz surfaces. The finished worktops are absolutely beautiful and have transformed my kitchen into a modern, minimalist space that I love spending time in. The quality of workmanship is outstanding, and the attention to detail really shows. I'm a very satisfied customer and would highly recommend In2stone to anyone considering new worktops. Well done to the entire team - you've exceeded my expectations!"— Ashley ChapmanGoogle Review
