Titanite, Diopside

Grenville titanites are prized among local rockhounds and international collectors alike but due to the tough environments they come from and the brittle nature of the crystals it can be difficult to get undamaged crystals. Thankfully, this locality is known for producing some hard angled, lustrous, crystals with razor sharp edges! They appear black or dark brown, but put a light up to one and you'll see they are more of a maroon red colour. This specimen appears more brown than normal and is attached to a matrix made up of titanite and green diopside crystals. Sharp!
