This is for a lot of sapphire rough from rock creek in Montana. These are unheated but I will include a photo of what they look like after heating for reference. These are smaller stones intended for melee probably ranging around 1.5-3mm or so. This lot would be best served for a jeweler to put stones into jewelry. These stones are facet grade with some great colors. 340g UNHEATED ROUGH ROCK CREEK MONTANA SAPPHIRE PARCEL
