Polishing Garnets And Tourmalines - International Gem Society



By far, the best combination for polishing garnets and tourmalines is a phenolic lap and an aluminium oxide (Al 2 O 3) abrasive.I've often used and recommended tin laps and oxide polishes for these stones, but tin laps are just too expensive. I've found that phenolic laps work just as well or better over time.
