Could be Sempervivum Bernstein or perhaps S. Big Slipper. The Hen and chicks varieties crossbreed very easily resulting in hundreds of varieties. The color has a tendency to bleach out with full sun exposure confusing identification further.
I sure like the color of the leaves and the spiky tips on your plant. The flowers are about the same shade as the flowers on my Red/Purple Hen and chicks.
You have a beautiful specimen.
