What Makes Radicaln Different
Description
Most stone coaster sets give you four, maybe six — enough until you have people over. This one is a set of eight, with a matching stone holder to keep them stacked and off the table when they're not in use. Each coaster is a 3.5-inch round disc of solid natural stone, hand-cut and polished, and the set comes in three colors: translucent green onyx, black marble, or white marble. Because the stone is natural, no two coasters carry the same markings.
8 round coasters · 3.5" diameter · matching stone holder (~1" deep) · green onyx / black / white · handmade natural stone · free US shipping · 30-day returns
What's included: 8 × round 3.5-inch stone coasters · 1 × matching stone holder · RADICALn fragile-safe packaging. Choose your color: green onyx, black marble, or white marble.
What makes this round coaster set different
A set of eight, not four
Most coaster sets stop at four or six. This one gives you eight — enough for a full table of guests without anyone going without, or spares for when a couple get used daily. It's the set to buy if four has ever not been quite enough.
A matching stone holder
The set includes a holder cut from the same stone, about an inch deep, that keeps all eight coasters stacked in one place rather than scattered across a drawer or table. The coasters sit inside it when they're not in use, so the set stays together and reads as one tidy object on a counter or table.
Three natural-stone colors
- Green onyx — a translucent, banded stone in amber, green, and rust tones that glows where light catches it. The most distinctive of the three, and no two are alike.
- Black marble — deep, opaque black with natural veining.
- White marble — clean, light stone with soft grey veining.
Choose the color that suits your table; each is solid natural stone, and each coaster's markings are unique.
Solid stone that protects the table
At 3.5 inches, each coaster covers the base of a glass, mug, or bottle, and the solid stone takes the ring, heat, or cold so your table doesn't. Stone coasters also sit flat and heavy — they don't stick to the glass and lift up the way thin cork or silicone ones do.
How this set compares
| This set (8 + holder) | Typical set of 4 | Cork / silicone | |
|---|---|---|---|
| Number of coasters | 8 | 4 | Varies |
| Matching stone holder | Yes | Sometimes | Rarely |
| Solid natural stone | Yes — marble / onyx | Varies | No |
| Each piece unique | Yes — natural markings | Varies | Identical |
| Stays flat, won't lift with glass | Yes — heavy stone | Usually | Often lifts |
The honest trade-off: a stone coaster set of eight costs more than a pack of cork or a set of four, and stone can chip if dropped on a hard floor. But you get double the usual count, a matching holder to keep them together, and coasters that are heavy, flat, and unique — a set that stays out as part of the table rather than hiding in a drawer.

How to use and care for your coasters
- Set a coaster under any cold or hot drink — glass, mug, bottle, or can.
- Stack them in the holder when not in use to keep the set together.
- Wipe with a soft, dry or barely-damp cloth; skip soap and harsh cleaners.
- Wipe up spills rather than letting liquid sit — natural stone is porous.
Note: because the stone is natural and porous, don't let liquids (especially wine, coffee, or anything acidic) stand on the surface — wipe them off.
Materials
Each coaster and the holder are cut and polished from natural stone. The green onyx color is translucent banded onyx — light passes through it, giving it a glow and showing the amber-and-green banding. The black and white colors are opaque marble, with natural veining. Because all three are natural stone, the markings vary from piece to piece, so your set won't be a pixel-perfect copy of the photo.
A note on natural stone: that variation is the stone, not a flaw. Marble and onyx are porous by nature, which is why the surfaces are polished and why spills should be wiped rather than left to sit.
Care instructions
- Wipe with a soft, dry or barely-damp cloth. Skip soap, which porous stone can absorb.
- Wipe up spills promptly — don't let wine, coffee, or acids sit on the surface.
- Stack them in the holder to keep edges from chipping.
- Handle with care — stone can chip if dropped on a hard floor.
Who this is for
- Anyone who entertains and needs more than the usual four coasters.
- Anyone who wants the set to stay tidy — the holder keeps all eight together.
- Anyone furnishing a warm or neutral table — green onyx for a striking look, black or white for a classic one.
- Gift buyers — a set of eight with a matching holder makes a complete, self-contained gift.
Good for: housewarmings, weddings, and Christmas or hostess gifts.
