It is a sedimentary stone — formed from ancient coral reef organisms compressed and mineralized over hundreds of millions of years. The distinctive surface patterns you see on each coral piece and across the coral board squares are the preserved outlines of actual marine organisms: coral polyps, shell fragments, and organic matter that lived in prehistoric seas. No two sections of fossil coral stone ever produce the same pattern. This means that the fossil coral pieces in your set are genuinely one-of-a-kind objects — not just unique to your set, but unique to the specific section of stone they were cut from.\u003c\/p\u003e\n\u003cp\u003ePaired with deep black marble — which provides the clean, high-contrast counterpoint that makes the fossil patterns read clearly — the black and fossil coral combination is the most texturally complex and visually detailed set in the RADICALn range. If you want a chess set that rewards closer inspection, this is it. The more you look at a fossil coral piece, the more geological detail you find.\u003c\/p\u003e\n\u003ch2\u003eBuilt for Curious Collectors, Serious Players, and Thoughtful Gifting\u003c\/h2\u003e\n\u003cp\u003eOn a coffee table or sideboard, this set provokes curiosity in a way that plain marble cannot — the fossil patterns invite guests to pick up pieces and look closely, making it as much a conversation piece as a chess set. In a study, library, or home office, it works as a permanent display object with geological significance. As a gift, the storage box makes it presentation-ready without additional wrapping, and the rarity of fossil coral stone gives the gift a narrative — something the recipient can explain and that no one else is likely to own.\u003c\/p\u003e\n\u003cp\u003eIt is a natural choice as a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eFather's Day gift for a chess-playing father or grandfather\u003c\/strong\u003e, a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eChristmas gift for a collector of natural materials\u003c\/strong\u003e, a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ehousewarming gift for a design-conscious homeowner\u003c\/strong\u003e, a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ebirthday gift for a chess enthusiast aged 40, 50, or 60\u003c\/strong\u003e, a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ewedding anniversary gift for a couple who appreciates natural stone objects\u003c\/strong\u003e, and a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eretirement gift for a man who has everything\u003c\/strong\u003e.

The warm beige-tan base color with dark brown fossil patterning is the natural color of the stone; no dyes, pigments, or surface treatments are applied. The black pieces and black board squares are carved from natural black marble — a dense, fine-grained metamorphic stone that polishes to a deep, consistent reflective surface. Each board is hand-cut from solid stone and squared by hand. Every one of the 32 pieces is individually hand-carved to Staunton form and hand-polished after carving. Because both stone varieties are natural materials, the precise arrangement of fossil patterns, the intensity of the dark brown detailing, and the depth of the black will vary slightly between sets — your set is a unique configuration of geological material that does not exist in duplicate form anywhere in the world.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoard size\u003c\/td\u003e\n\u003ctd\u003e15 × 15 inches (38 × 38 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoard thickness\u003c\/td\u003e\n\u003ctd\u003e0.04 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKing height\u003c\/td\u003e\n\u003ctd\u003e3.5 inches (8.9 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQueen height\u003c\/td\u003e\n\u003ctd\u003e3 inches (7.6 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBishop height\u003c\/td\u003e\n\u003ctd\u003e2.75 inches (7 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKnight height\u003c\/td\u003e\n\u003ctd\u003e2.75 inches (7 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRook height\u003c\/td\u003e\n\u003ctd\u003e2.75 inches (7 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePawn height\u003c\/td\u003e\n\u003ctd\u003e2.5 inches (6.4 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal weight\u003c\/td\u003e\n\u003ctd\u003e~10.5 lbs (~4.76 kg) complete set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal items\u003c\/td\u003e\n\u003ctd\u003e33 (1 board + 32 chess pieces)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePiece count breakdown\u003c\/td\u003e\n\u003ctd\u003e2 Kings · 2 Queens · 4 Bishops · 4 Knights · 4 Rooks · 16 Pawns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePiece colors\u003c\/td\u003e\n\u003ctd\u003e16 fossil coral stone pieces · 16 deep black marble pieces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePiece style\u003c\/td\u003e\n\u003ctd\u003eStaunton form, hand-carved\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial — board\u003c\/td\u003e\n\u003ctd\u003eNatural black marble (frame \u0026amp; dark squares) + natural fossil coral (light squares)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial — pieces\u003c\/td\u003e\n\u003ctd\u003eNatural fossil coral stone (16 pieces) + natural black marble (16 pieces)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eHand-polished natural surface on all pieces and board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase protection — board\u003c\/td\u003e\n\u003ctd\u003eAttached felt bottom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase protection — pieces\u003c\/td\u003e\n\u003ctd\u003eIndividual felt bottoms for all 32 pieces (included in packet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage\u003c\/td\u003e\n\u003ctd\u003eLuxury storage box included at no extra cost\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible board sizes\u003c\/td\u003e\n\u003ctd\u003eStandard 15–18 inch chess boards\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUse\u003c\/td\u003e\n\u003ctd\u003eIndoor use only — not suitable for outdoor use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e1E-JWAD-725I\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2\u003eHow to Care for Your Black \u0026amp; Fossil Coral Marble Chess Set\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCleaning:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eWipe board and pieces with a slightly damp soft cloth and dry immediately.
