London Blue topaas



We only supply to wholesale dealers, jewellers and goldsmiths (in training). Since the foundation in 1990 BirGem specializes in colored gemstones. As an example we have standard sizes and shapes in amethyst and smoky quarts as well as unique sapphires, tourmaline and spinel.

Over the years we have expanded our already wide product range with single pearls, pearl strings and gemstone strings. Many articles are available from our own stock. Thanks to good connexions and different European gemstone cutters as well as our usual cutter in India, we are proud to be able to deliver almost any custom cut gemstone you can think of.
