15 Inches Chess Sets
Shop 15 Inch Chess Sets by Stone
The 15 inch tier carries the deepest stone variety in the RADICALn collection. Black and white marble remains the classic, universally recognized pairing, available as a standard set, with a storage box, or in our medieval figurative antique style. Fossil coral — a sedimentary stone carrying genuine ancient fossil organism patterns — pairs with black marble, dark brown marble, or red marble, each combination offering a different warm-toned character. Green onyx, a naturally translucent chalcedony variety, pairs with white marble across standard, storage box, and our most premium antique configuration. Multi green onyx offers a bolder, more dramatically banded alternative paired with black marble. Oceanic grey marble brings a cooler, more grounded palette in both white-dominant and grey-dominant configurations. Black and golden marble rounds out the collection with a distinctive warm-metallic pairing.

Medieval Figurative Antique Chess Sets — Available Only at 15 Inches
Our antique-style sets are carved in medieval figurative style rather than standard Staunton form — robed kings and queens, mitred bishops, mounted knights, and architectural rook towers, in the broad tradition of historical artefacts like the Isle of Lewis chessmen. Every piece receives a hand-distressed finish for an aged, weathered character that no Staunton set offers, and every antique set includes a fitted storage box at no extra cost. This entire line is exclusive to the 15 inch size — there is no 12-inch medieval figurative option.
- Black & White Antique ($171.35) — the classic high-contrast pairing in historical carving
- Black & Coral Antique ($171.35) — genuine fossil coral against deep black marble
- Coral & Red Antique ($171.35) — an all-warm fossil coral and red marble pairing
- White & Green Antique ($214.90) — RADICALn's most premium product, pairing the rarest stone in our collection with the most labor-intensive carving style
15 Inch Chess Sets With and Without a Storage Box
The 15 inch size is the only tier in the RADICALn collection where a storage box is available — our 12-inch sets never include one. Every medieval figurative antique set includes a storage box as standard. Several Staunton-style 15-inch sets are also available in a matched pair: a lower-priced standard version and a storage box version using identical stones, letting you choose based on whether protected storage and gift presentation are worth the price difference.
- With storage box: Black & White ($172) · Black & Fossil Coral ($172) · White & Green Onyx ($172) — plus all four antique sets listed above
- Without storage box (standard, lower price): Black & White ($149) · Black & Fossil Coral ($125.90) · Green Onyx & White ($125.90) · Fossil Coral & Dark Brown ($125.90) · Black & Multi Green ($125.90) · White & Grey Oceanic ($125.90) · Grey Oceanic & White ($125.90) · Black & Golden ($125.90)
Need Just the Board?
If you already own a set of pieces and need a replacement board, or want to build a custom pairing of board and pieces from different products in this collection, our 15 inch board-only listing is available starting at $79.35 in five color combinations — the lowest-priced way to bring a genuine natural stone surface into your home.
Why Choose a 15 Inch Chess Set
At 15 inches, a marble chess board has the scale to function as a genuine living room or game room centerpiece rather than a desk accessory. Larger pieces — Kings typically standing 3 to 3.5 inches depending on style — are more comfortable for extended play sessions and for players with larger hands. This is also the only size where the medieval figurative antique line and storage box options exist, making it the natural choice for serious gifting: a milestone birthday or anniversary gift for a collector, a Christmas gift at the premium end of the price range, or a housewarming present for a living room built around real furniture and real display surfaces.

Frequently Asked Questions
A 15 inch marble chess set has a 15 × 15 inch board (38 × 38 cm), with King pieces typically standing between 3 and 3.5 inches tall depending on the style. This is RADICALn's full-size board, scaled for coffee tables, game rooms, and serious regular play.
RADICALn's 15 inch marble chess sets range from $125 for standard Staunton-style sets to $214.90 for our most premium medieval figurative antique set. Storage box versions typically run around $172, and antique sets with storage box included range from $169 to $214.90. A board-only option is also available starting at $79.35.
Every medieval figurative antique set includes a storage box at no extra cost. Several Staunton-style sets also offer a storage box version at a higher price point — Black & White, Black & Fossil Coral, and White & Green Onyx are each available both with and without storage. The 12-inch size never includes a storage box, making 15 inches the only tier where this option exists.
A medieval figurative chess set uses pieces carved as actual representational figures — robed kings and queens, mitred bishops, mounted knights, and architectural rook towers — rather than the abstract geometric Staunton forms used in standard tournament chess. The style is in the broad tradition of historical artefacts like the Isle of Lewis chessmen. RADICALn's antique-style 15-inch sets use this carving style with a hand-distressed finish; this line is exclusive to the 15 inch size.
The 15 inch tier carries the deepest stone variety in the collection: black and white marble, fossil coral (paired with black marble, dark brown marble, or red marble), green onyx (in standard, storage box, and antique configurations), multi green onyx, oceanic grey marble in two colour hierarchies, and black and golden marble.
The White & Green Antique set at $214.90 is RADICALn's most premium product. It pairs green onyx — the rarest stone in the collection — with medieval figurative carving and a hand-distressed antique finish, and includes a storage box. It represents the combination of the rarest material and the most labour-intensive carving style RADICALn offers.
Both sizes use identical stone varieties and the same hand-carving process. A 15-inch King stands roughly 3 to 3.5 inches tall versus 2.75 to 3 inches on a 12-inch King. The 15 inch size is the only tier with storage box options and the only tier carrying the medieval figurative antique line. Choose 15-inch for coffee tables, game rooms, comfortable extended play, and serious gifting; choose 12-inch for desks, compact spaces, and budget-conscious purchases.
Yes — RADICALn offers a 15 inch board-only listing starting at $79.35, available in five colour combinations. This is useful for replacing a damaged board, or for buyers who want to pair a board from one product with pieces from another.
Fossil coral is a sedimentary stone formed from the compressed remains of ancient coral reef organisms, carrying genuine fossil organism patterns unique to every piece. At 15 inches, fossil coral is available paired with black marble (standard, storage box, and antique versions), with dark brown marble, and with red marble (standard and antique versions).
Green onyx is a naturally translucent variety of chalcedony that shifts between forest green, amber, and cream tones in different light. At 15 inches, it is available paired with white marble in standard, storage box, and antique configurations — the antique version is RADICALn's single most premium product at $214.90.
Antique sets are fully playable — each piece is identifiable by its figurative form, the same way Staunton pieces are identifiable by their abstract shapes. The finer sculptural detail and hand-distressed finish make them slightly more suited to careful, considered play than the smooth standard sets, and the included storage box lets you move the set between display and protected storage between games.
Our medieval figurative antique sets are the most distinctive gift option for collectors and history enthusiasts, particularly the White & Green Antique set, which combines the rarest stone in the collection with the most labour-intensive carving style. Fossil coral sets are also a strong choice, since each piece carries genuine ancient fossil organism patterns.
Wipe pieces and boards with a slightly damp soft cloth and dry immediately. Never use acid-based cleaners such as vinegar, lemon juice, or bleach. For antique-style sets, never attempt to polish or buff the hand-distressed surface — this is intentional and cannot be restored once removed. Store pieces separated in soft cloth bags between uses, and use the included storage box for antique sets to keep pieces protected.
Yes — every 15 inch marble chess set ships free to US addresses, with an estimated delivery of 4 to 9 business days. All sets are covered by RADICALn's 30-day return policy.
RADICALn's medieval figurative antique sets are carved in the broad historical tradition of artefacts like the Isle of Lewis chessmen — robed monarchs, mitred bishops, mounted knights, and architectural rooks rather than abstract Staunton forms. These are not direct replicas of the Lewis chessmen specifically, but use the same figurative carving approach across four colour pairings, all available only at 15 inches.
