A Sanitising cycle only takes 3 minutes, and an audible voice tells you when sanitisation is complete.
We have been asked by a number of people if there are any items which SHOULD NOT be subject to UV light. Having spoken to leading gemstone specialist it is suggested to avoid sanitising the below items with this unit:
Non heat-treated Sapphires
And any other stones that are affected by light or UV.
If in doubt, we would suggest seeking alternative methods of Sanitisation.
