Here’s a temporary description of some of the better-known gem kinds of garnet gems:
Almandine
Almandine is maybe the commonest of the garnet household, and is the deep purple to red-brown stone most frequently considered when individuals consider garnet. It’s a reasonable stone, however new mines in east Africa are producing Almandine in additional fascinating purple to red-orange colours which don’t have any brown undertones. The foremost sources of Almandine are Madagascar, India and Sri Lanka. Almandines are generally accessible in massive sizes, and most garnet sculptures are finished in Almandine. Complete cups or vases have been comprised of single crystals. Due to its depth of shade and saturation, some faceted gems reduce too massive from this deeply coloured materials is not going to sparkle as a result of they’re too darkish to mirror the sunshine.
Rhodolite
Rhodolite is the title used to explain the beautiful pinkish, purplish or lavender Pink Garnets that are a mix of Almandite and Pyrope.

Tsavorite
Tsavorite is essentially the most fascinating of all garnets, with a beautiful purity and depth of its lovely inexperienced shade. Till Tsavorite was found within the late 1960’s there was no different gemstone however emerald that would supply the gem purchaser such a wealthy, darkish inexperienced shade. This magnificent inexperienced garnet has been in nice demand for jewellery since its discovery, and for good causes: it’s more durable than emerald, extra sturdy in jewellery, much less included than emerald, extra sensible when faceted, and is far rarer than emerald. Briefly, it’s (by all counts) a greater gemstone, nevertheless it lacks the magic and the antiquity of the title “emerald”. Because of this it’s identified to far fewer individuals, is in a lot decrease demand, and is subsequently a lot inexpensive than emerald of comparable shade. Even so, due to its magnificence, Tsavorite is the costliest of the garnet household. It’s truly a type of Grossular, coloured inexperienced by the presence of hint quantities of the metallic vanadium.
Tsavorite was first unearthed in Tanzania and Kenya; the title “Tsavorite” is definitely a commerce title created by Tiffany and Co., in reference to the Tsavo Nationwide Park in Kenya (situated close to the Tsavorite locality). The geology of Tsavorite is such that the provision is extraordinarily sporadic. The warmth and folding of the rock lots of of thousands and thousands of years in the past which fashioned Tsavorite additionally shattered many of the crystals. It is rather uncommon to search out Tsavorite in sizes bigger than 5 carats, and most faceted stones are under two carats. Many deposits of Tsavorite are small and unpredictable: seams all of the sudden slim and disappear, giving no indication the place to look subsequent. Many of the tough is very shattered in place (as a result of earth actions over the centuries), which accounts for the nice 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 business portions. The Scorpion Mine in southeast Kenya is now producing from tunnels sunk on an incline for greater than 200 ft. The opposite main producer on this space has a big open-cast operation to a depth of 40 ft which has yielded a substantial amount of Tsavorite. Sadly, the house owners are unable to proceed mining by this methodology and are starting to introduce underground mining. Just lately, a brand new Tsavorite-producing space was found in Lokirima, a few thousand kilometers northwest of the beforehand identified localities. Though this locality is barely producing a small amount, it’s promising that the potential of discovering Tsavorite exists over a wider space than beforehand thought.
Tsavorite garnet has greater than tripled in value since its introduction to {the marketplace}, however at present value ranges it nonetheless sells at a tenth or much less of the worth of emerald of comparable high quality. Stones over 2 carats are extraordinarily uncommon, and 5+ carat gems of high-quality shade are digital museum items.
