Type 2 gemstone
Tourmalines are closely related gemstones which have been created by Nature in many different colours. In the trade, as a rule, it is not the case that each individual variety has its own name. Instead, the name tourmaline is used and the colour simply added, hence red, green, blue or yellow tourmaline. The exception, however, proves the rule. This also applies to the tourmaline and, in particular, to red and pink specimens.
Whilst coloured gemstones in good qualities should as a rule be as free of inclusions as possible, they are looked upon with some favour in the case of the rubellite: indeed it is inclusions that render this stone really interesting from the point of view of the connoisseur. Having said that, they should be subtle, and they must not upset the way in which the light passes through this magnificent gemstone, for that could make it look cloudy or milky. Nevertheless, a rubellite with only a few fine inclusions is of course more valuable than one with inclusions which are clearly visible.
Type 1 Gemstones The following gemstones are typically inclusion free, even minor inclusions detract from their value. Diamond, Amethyst, Beryls(Aquamarine,Morganite), Citrine, Smoky Quartz, topaz, Chrysoberyl, Kunzite, Tanzanite, green Tourmaline, and Blue Zircon IF Internally flawless under extreme magnification (Very rare) F Flawless VVS Minute inclusions under 10x; invisible to the unaided eye VS Minor inclusions under 10x; usually invisible to the unaided eye SI1 Noticeable inclusions under 10x; usually visible to the unaided eye SI2 Noticeable inclusions under 10x; usually quite visible to the unaided eye I1 prominent- moderate affect on appearance or durability I2 prominent - severe affect on appearance or durability I3 prominent- severe affect on beauty, transparency or durability Type 2 Gemstones Gemstones that normally have small inclusions that do not detract from value.
