Almandine
Almandine might be the most typical of the garnet household and is the deep purple to reddish brown stone that the majority usually involves thoughts when individuals consider garnets. It’s a low-cost stone, however new mines in East Africa are producing Almandine in probably the most fascinating purple to orange-red colours, which don’t have any brown undertones. The primary sources of Almandine are Madagascar, India and Sri Lanka. Almandines are generally out there in giant sizes, and most garnet sculptures are made in Almandine. Total glasses or vases are constituted of single crystals. Due to its depth of coloration and saturation, some very giant gems reduce from this deep-colored materials is not going to sparkle as a result of they’re too darkish to mirror mild.
Rodolith
Rhodolite is the title used to explain the attractive pink, purple or lavender purple garnets, that are a mix of almandite and pyrope.

Tsavorite
Tsavorite is probably the most fascinating of all garnets, with an exquisite readability and depth of its lovely inexperienced coloration. Till Tsavorite was found within the late Sixties, there was no different gemstone aside from emerald that might provide the gem purchaser such a wealthy, darkish inexperienced coloration. This magnificent inexperienced garnet has been in excessive demand in jewellery since its discovery, and for good purpose: it’s tougher than emerald, extra sturdy in jewellery, much less concerned than emerald, extra good when faceted and is far rarer than the emerald. Briefly, it’s (on all counts) a greater gemstone, however it lacks the magic and antiquity of the title “emerald”. Due to this, it’s recognized to far fewer individuals, is in far decrease demand, and is due to this fact far inexpensive than emeralds of comparable coloration. Nonetheless, as a consequence of its magnificence, Tsavorite is the costliest of the garnet household. It’s truly a type of grossular, coloured inexperienced by the presence of small quantities of the metallic vanadium.

The geology of Tsavorite is such that provide is extraordinarily sporadic. The heating and folding of the rock tons of of hundreds of thousands of years in the past that shaped Tsavorite additionally destroyed a lot of the crystals. It is extremely uncommon to seek out Tsavorite in sizes bigger than 5 carats, and most faceted stones are beneath two carats. Many Tsavorite deposits are small and unpredictable: the seams slim abruptly and disappear, giving no indication of the place to look subsequent. A lot of the tough may be very fragmented in place (as a consequence of earth actions over the centuries), which accounts for the good rarity of enormous, clear stones.
There have been maybe 40 completely different areas the place Tsavorite has been mined, however solely 4 mining ventures are nonetheless producing in industrial portions. Scorpion’s mine in southeastern Kenya is now producing from tunnels sunk right into a slope for greater than 200 meters. The opposite main producer on this space has a big open pit operation at a depth of 40 toes which has produced a major quantity of Tsavorite. Sadly, the homeowners are unable to proceed mining with this methodology and have begun to introduce underground mining. Lately, a brand new space of Tsavorite manufacturing was found at Lokirima, a few thousand kilometers northwest of the beforehand recognized localities. Though this locality is producing solely a small quantity, it’s promising that the potential of discovering Tsavorite exists in a wider space than beforehand thought.
Tsavorite garnet has greater than tripled in value since its introduction to the market, however at present value ranges it nonetheless sells for a tenth or much less of the value of emeralds of comparable high quality. Stones over 2 carats are extraordinarily uncommon, and fantastically coloured 5 carat gems are digital museum items.
