I use Nanogems in my Strovia and Asteris necklaces. Nanogems are laboratory made and can withstand the temperatures needed to fire silver clay. A lot of natural stones can’t.

This chart should help you select the appropriate nanogem if you are buying a birthday or anniversary gift. Have a look in the shop for pictures of the full range. The ruby ones are shown here.

It’s hard to capture the exact colour of the gems and, what colour you see will also depend what screen you are viewing them on. The photos were taken using natural light with minimal editing to make sure you see as close to the gemstone colour as possible.
