Know the wood before you buy the wood. Six things worth understanding.
Agarwood is not a species of wood you can fell and sell. It is resin-infused heartwood: when trees of the Aquilaria genus are wounded or stressed, they produce a dark, fragrant resin as a defense response. Wood without resin is just pale timber; wood with enough resin is agarwood — and the grade depends on how much resin, and how well it has matured.
This is why every piece is different, why photos matter, and why honest sellers state measurable facts instead of adjectives.
Wild agarwood is scarce, uneven, and — critically — a CITES-regulated resource (Aquilaria species are listed in Appendix II). The legal, sustainable future of this trade is cultivated agarwood: planned plantations, controlled induction of resin, documented batches.
Our supply is plantation-grown. That is not a compromise — controlled induction plus a good cultivar gives stable resin quality and traceable batches, which wild material can never promise.
Sinking grade (沉水) means a piece is dense enough to sink in water — a proxy for resin saturation. It is a useful, checkable test, which is why we like it:
We declare the grade in writing on every quotation. If a seller won't put it in writing, that tells you something.
Resin shows as dark lines and patches between the pale wood fibers. On beads, look for even, flowing oil lines rather than blotchy stains. On raw material, richer dark grain near the center usually means deeper resin. We photograph the oil lines of every lot we quote.
Good agarwood does not shout. On an electric heater at 100–150°C, resin releases in layers — often sweet woody notes first, then deeper balsamic tones. Harsh, sharp, alcohol-like hits usually mean fast processing or added fragrance. Trust your nose at low temperature, not the seller's adjectives at high volume.
Qinan (奇楠, kinam) is the most coveted class of agarwood — softer, oil-rich material that yields a uniquely layered aroma and even melts differently when heated. True qinan is rare and priced accordingly. Our "Qinan No.1" cultivar was selected and propagated from the Jianfengling (Hainan) lineage to bring qinan-class material into sustainable, traceable cultivation.
