|Origin||TURKEY – RUSSIA- CANADA|
Howlite, which is named for its discoverer Henry How (a Nova Scotia geologist), is one of those minerals that is more famous for imitating another mineral. In this case the other mineral is turquoise, a phosphate gemstone. Although howlite is always white or gray, it can accept dyes fairly easily and be dyed a turquoise blue. The look of turquoise is so good that dishonest dealers have been unfortunately successful at this hoax.
In more honest circumstances, dyed howlite is an affordable substitute for turquoise carvings, beads, polished stones and cabochons. It accepts a nice polish and its porcelaneous luster is attractive and enhances even undyed beads and carvings. Unfortunately it has low hardness, but it still has a distinct toughness. California is the source for almost all of the howlite trade where nodules of up to one hundred pounds have been found.
Howlite is found in continental evaporite deposits with other borate and evaporite minerals. It forms in nodules that appear like the heads of cauliflower, crystals faces on the nodules are rare. Veins of black web-like streaks often are interlaced throughout the nodules, adding to their character. Slabs of howlite are often painted with scenes and designs that make artistic use of these veins. Datolite and bakerite a couple of other boro-silicates, form similar looking nodules, but are distinctively harder. Massive magnesite can also be confused with howlite, but it has good cleavage.
Howlite as is listed above, is often a confusing mineral to classify. The silicon atom in its formula would normally require its classification as a silicate mineral. But some classification schemes prefer to place howlite with other borate minerals in the carbonates class because it has five borons to only one silicon and that its character and formation are more in line with other borate minerals such as colemanite, ulexite, borax and kernite.
In general, the more transparent it is and the more blue its adularescence, the higher the value. Large quantities of near opaque material with various body colors is carved into simple “moon faces” and other figures which are available for pennies. Cabs of translucent material which are either white or with pleasing body color and adularescence are fairly common in the market and command relatively modest prices.
For cat's eyes and the occasional star, expect to pay in proportion to the beauty of eye, size and clarity. In rare instances, the schiller phenomenon is multicolored showing blue, with green and/or orange. Such stones are quite valuable and are known as rainbow moonstone. Unfortunately, a lot of low grade, labradorite feldspar is advertised and sold by that name, (a misnomer,) so most people are surprised by the prices of the real gem grade rainbow stones.
By far the most valuable moonstones are those which are colorless, transparent and have a strong blue sheen. Such stones historically came from Burma. Unfortunately this material is essentially mined out, so most top grade, blue sheen gems available today are being passed from one dealer, or collector, to another and prices are escalating.
