They almost look like they have a rainbow in them when held under direct sunlight.
They are also known as Titanite and measure 5.5 to 6.0 on the Mohs Scale of Hardness. Setting sphenes is like setting opals, it needs to be done with care and precision without much use of heat.
The color on these stones is very stable and will not change or fade in direct or indirect sunlight.
