Another possibility for imitating sapphire (blue corundum) is '''blue quartz''', which gets its coloration from inclusions of ''crocidolite'' or ''rutile fibers''. Yet another possibilty is '''dumortierite quartz''', also known as ''blue aventurine''. The latter tends to be semi-opaque, while blue quartz is more translucent (compare with ''green aventurine''). I haven't seen enough of either on the market to judge their respective qualities. Based on what little I have seen, I tend to favor the blue quartz over the blue aventurine. I have seen some rather nice specimens of blue quartz, from Madagascar, being sold on the internet. Both matierials have a Mohs hardness of '7', making them durable enough for any jewelry application. Blue aventurine tends to resemble ''denim lapis'' rather than corundum. Both types of quartz are less expensive than blue topaz (roughly half the cost). The trick is finding a reliable supply. |

This is a cool article. I was under the impression that fake gemstones were period no? I heard once they were made out of glass or glass paste. I have seen similar things in museums. [[User:Sabine|Sabine]] 06:59, 21 November 2006 (EST) |
