The Rarest Stone in the Collection, Now at Full Size

Green onyx is a variety of chalcedony — microcrystalline quartz, not standard marble — with a natural semi-translucency that makes the pieces appear to shift between forest green, warm amber, and cream depending on the light source and viewing angle. It is the rarest stone in the entire RADICALn collection and the one that draws the most attention from people who encounter it in person. At full 15-inch size, the larger board surface and larger pieces give the green onyx banding more room to display its color range than the 12-inch version does — the amber striations and forest-green base tones are more visually pronounced at this scale.

This is the standard version of the set, without a storage box — the right choice for buyers who want full-size genuine green onyx at a more accessible price than the storage box or antique versions, and who plan to keep the set on permanent display rather than packing it away between uses.

Built to Be a Conversation Starter on Any Coffee Table

At 15 inches, this set has the scale to function as a genuine living room centerpiece. The green onyx's multi-tonal color behavior — appearing more green in some light, more amber in others — makes it the single most visually engaging chess set in the RADICALn collection when displayed in starting position on a coffee table or game room surface. It suits colorful, vibrant, organic modern, and Mediterranean interiors particularly well, while still working in more neutral spaces as a deliberate statement piece.

As a gift, the rarity and visual distinctiveness of green onyx make this one of the most memorable options in the collection — a milestone birthday gift for a collector or natural stone enthusiast, a housewarming present for a colorful or eclectic new home, a St. Patrick's Day gift where the green tones align directly with the occasion, and a Christmas gift for someone who already owns a standard black and white chess set and is ready for something rarer.

Materials & Craftsmanship — Green Onyx and White Marble, Full Size

Green onyx is a variety of chalcedony — microcrystalline quartz — that forms in geological bands producing a characteristic multi-tonal coloring: forest green as the base tone, warming to amber, cream, and occasional orange-red depending on the specific section of stone. The stone is naturally semi-translucent — light penetrates it rather than simply reflecting from the surface, giving green onyx pieces a depth of color that changes with the viewing angle and light source throughout the day. No two green onyx pieces in any set carry the same tonal combination, because each piece is cut from a different section of the stone's banding.

The white pieces and board squares are carved from natural white marble, providing the clean, bright contrast that allows the green onyx tones to read fully against it. Each board is hand-cut from solid stone and squared by hand. Every piece is individually hand-carved to Staunton form at full 15-inch scale and hand-polished after carving. The green onyx color variation in your set will differ from the product photography because the specific banding cross-section of each piece depends on where it was cut from the original stone block — your set's specific tonal arrangement is unique.

How to Care for Your Green Onyx & White Marble Chess Set

• Cleaning: Wipe board and pieces with a slightly damp soft cloth and dry immediately. Do not leave water sitting on the green onyx surfaces — the stone is porous enough to absorb moisture over time despite being harder than standard marble.
• What to avoid: Never use acid-based cleaners — vinegar, lemon juice, bleach, or standard household sprays permanently damage both green onyx and white marble. Use only a dry cloth for regular maintenance or a pH-neutral stone cleaner.
• Preserving the green onyx tone: The multi-tonal green, amber, and cream tones of green onyx can shift with prolonged direct sunlight. UV exposure causes gradual color change in translucent stone varieties more visibly than in opaque stones. Position the board away from direct window light for long-term tonal preservation.
• Storage: Store pieces separated in soft cloth bags between uses to prevent contact scratching between the green onyx and white marble pieces.
• Handling: Green onyx is harder than standard marble but can fracture if dropped from height. Contact us if a piece is damaged — our replacement service will source a matching green onyx or white marble replacement.
