This paper reports the results from a second characterisation of 91500 zircon, including data electron probe microanalysis, laser ablation inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS), secondary ion mass (SIMS) and fluorination analyses. The focus this initiative was to establish suitability large single zircon crystal for calibrating in situ analyses rare earth elements oxygen isotopes, as well provide working values key geochemical systems. In addition extensive testing chemical structural homogeneity sample, occurrence banding both backscattered cathodoluminescence images is described detail. Blind intercomparison reported by LA‐ICP‐MS SIMS laboratories indicate that only small systematic differences exist between sets provided these two techniques. Furthermore, use NIST SRM 610 glass calibrant found introduce little or no error into zircon. Based on data, seems be very suited isotopic
