Indian Sandalwood

Indian Sandalwood is the fragrant heartwood of Santalum album, a small hemiparasitic evergreen tree native to India and parts of Southeast Asia. Unlike most timber trees it is grown and harvested chiefly for its scent: the heartwood and the essential oil distilled from it (rich in santalol) have been central to Indian religious, cosmetic, and perfumery use for thousands of years.

The tree is modest in size — typically 15 to 30 ft — and roots partly parasitically on neighboring host plants. Only the inner heartwood carries the prized aroma; the pale outer sapwood is nearly scentless. The sample shown is characteristic: a fine, uniform grain with subtle figuring in a warm golden-brown to reddish-brown that deepens with age. Because supply is tightly controlled and the wood extraordinarily valuable, it is encountered far more often as small carving stock, beads, and oil than as boards.

The heartwood ranges from warm golden-brown and honey-yellow to a deeper reddish-brown, darkening with age and exposure, and is clearly distinct from the pale, almost white sapwood that gives the species its "white sandalwood" name. The grain is fine, straight to slightly wavy, and very uniform, often with subtle figuring and a smooth, waxy luster — matching the sample's fine, even grain and warm golden-brown to reddish-brown color.

It is a dense, close-textured wood — roughly 55–60 lb/ft³ (about 900–950 kg/m³) dried — and hard, on the order of 2,000 lbf on the Janka scale, yet it carves cleanly because of its fine, oily, even grain. The heartwood is oily and naturally durable, resistant to insects and decay, and famously retains its fragrance for decades. That persistent aromatic oil, not structural performance, is the wood's defining property.

Sandalwood's overwhelming value is aromatic and decorative rather than structural. The heartwood is distilled for sandalwood essential oil used in fine perfumery, incense, cosmetics, soaps, and aromatherapy, and the powdered wood is used for incense, sandalwood paste, and religious and ceremonial purposes across South Asia.

As a wood it is a premier carving and turning material: intricately carved figures, boxes, fans, combs, prayer beads and malas, and small ornamental objects take advantage of its fine grain and lasting scent. It also appears as inlay, marquetry accents, and in small luxury goods. It is essentially never used for flooring, framing, or large furniture — both because pieces are small and because the wood is far too valuable and scarce for bulk use.

For its density, sandalwood works remarkably well. The fine, even, oily grain carves and turns cleanly with sharp hand and machine tools, holds crisp detail, and finishes to a naturally smooth, lustrous surface with little effort. Its natural oils can, however, interfere with some glues and film finishes, so joints and coatings may need surface preparation; many pieces are simply buffed or left unfinished to preserve the scent.

The most notable working trait is its persistent fragrance, released strongly during sawing, carving, and sanding — generally regarded as pleasant. That said, sandalwood oil and dust can cause skin irritation or allergic contact dermatitis in sensitive individuals, and as with any fine hardwood dust, sensible dust extraction and a mask are advisable. Test finishes on offcuts, since the oil content is high.

Indian Sandalwood is among the most valuable woods in the world by weight, and genuine Santalum album heartwood commands premium prices — traded by the kilogram, not the board foot, in the same league as the costliest exotics. It is generally available only as small carving blanks, offcuts, beads, powder, and oil rather than as lumber.

Sustainability and legality are serious concerns. Over-harvesting has made wild Santalum album scarce; the IUCN has assessed it as Vulnerable, and its harvest and trade are heavily regulated in India, where the state historically held ownership of sandalwood trees and smuggling is a persistent problem. It is not currently listed on the CITES appendices, but national and state controls are strict. Much legitimate supply now comes from plantation cultivation (including large plantings in Australia). Buyers should insist on legally sourced, documented material and be wary of cheaper substitutes sold as "sandalwood."
