The Rising Value of Kauri Gum
Kauri gum exists in a unique position — it is no longer being created, yet continues to be discovered in limited quantities. As access becomes more restricted and awareness grows, the supply of high-quality pieces naturally tightens while demand expands across collectors, artists, and private buyers.
This creates a shift from commodity to collectible. Individual specimens are increasingly judged not just by weight, but by clarity, formation, and provenance. Registered pieces in particular carry an added layer of recognition, making them more desirable over time as part of a documented archive.
As New Zealand’s ancient forests become further removed from the present, kauri gum stands as one of the last tangible connections to that era — a material that is not only rare, but historically grounded and increasingly valued in its own right.
Over recent years, the value of New Zealand kauri gum has seen a sharp and consistent rise, driven by increasing global interest, dwindling supply, and its growing recognition as both a natural resource and collectible material. Once traded primarily as an industrial resin, kauri gum is now firmly positioned within the luxury, jewellery, and collector markets. Pricing varies significantly depending on size, clarity, colour, and preservation, but a clear trend has emerged: Finished jewellery-grade gum commonly sells between $10–$30 per gram, particularly for polished, inclusion-free pieces with strong visual appeal. Large specimen pieces especially those suitable for carving or display typically range from $2–$30 per gram, depending on quality and uniqueness.
Historical records reinforce this trajectory. A widely cited 2010 auction sale saw an approximately 18kg lump sell for around $2 per gram, marking one of the first publicly documented high-value benchmark sales.
However, the true top end of the market often exists beyond public auctions. Private sales of museum-grade kauri gum featuring exceptional clarity, rare inclusions, or significant size are known to reach upwards of $30,000 per kilo ($30 per gram), with some pieces commanding even higher prices among collectors.
As supply continues to diminish and demand grows particularly from international collectors, artists, and heritage buyers kauri gum is increasingly being viewed not just as a material, but as a finite natural asset. Its value is no longer tied solely to weight, but to story, rarity, and provenanc
About These Grades These classifications represent the most commonly recognised types of kauri gum, based on colour, clarity, and natural formation. They provide a practical framework for identifying and comparing specimens across the majority of material found. However, kauri gum can also occur in far rarer variations. Unusual hues such as blue, green, and even purple have been observed, typically formed under unique environmental conditions or through trace mineral influence. These pieces are exceptionally scarce and sit outside standard classification, often valued for their rarity and uniqueness rather than fitting within typical grading categories.
