This collection presents mostly « rare gems » or « collector gems », more often not used in jewellery because of rarity or hardness. Rarity is due to the quantity available, or a rare color, source or inclusion, or the difficulty to cut the rough into a faceted gem. Microphotographies are taken with an old Olympus microscope and an iphone. These gems are not for sale, but some extra specimens may be available. The collection is visible but stored in a specific location, so please contact me for an appointment.
The collection brings together a selection of rare garnets, among them a very rare Leuco and different color changing gems from different locations.
The colorless grossular garnet or Leuco Garnet is the rarest of all garnets and an extremely rare gem. Like 99% this one display a very light yellowish color, otherwise a good clarity. It comes from Myanmar.
This garnet is a grossular from South Africa. It was tested with a Raman spectroscopy to confirm the presence of vanadium.
A Spessartine garnet from Africa. The mandarin color is one of the most valuable in garnets. That specimen doesn’t present many dispersion as requested for the top specimens but that’s why I like it so much, it looks like sirup and almost artificial (but untreated).
This small Chrome Pyrope is an Anthill garnet. It comes from the Navajo Indian Reservation in Arizona, and is not mined. Small ants Digg the ground to create their homes and that’s how some garnets can be gathered time to time around the anthills! Most of these stones are under one carat, to this is a very good size for this uniquer and rare gem.
This rare Pastel Pyrope garnet is a mix of Pyrope and Almandine and just a bit of spessartine (often wrongly categorized as rodholite). It was discovered in 1998 and comes from Morogoro in Tanzania. It has a color shift pink to red
This is the scarce but famous Bekily garnet. Until 1998 and the spectacular find in Bekily, Madagascar, blue garnet were absolutely unknowns on Earth. The color change is very good from blue to purple, and the gem is quite clear despite a big but wonderful inclusion.
This Pyrope-Spessartine is a rare color changer garnet from Kenya, probably the Taita deposit, found in 2010.
A rare Pyrope-Spessartine garnet from Masasi, Tanzania, displaying a beautiful color change from bluish green to pink.The gem also feature iridescent needle inclusions specific to this deposit.
A small grossular tsavorit, chrome and vanadium rich named Tsavorite. Color is a bit light but clarity is ok.
The rare iridescent handratite garnet comes from Nara, Japan. Here the crystal is preserved and untouched.
A russian chrome andratite garnet, or demantoid, from Tagil Bobrovka, Ural, Russia, with chrysotile inclusions called horsetail. The best have a vivid green and horsetail is spreading from a central point. But this one comes directly from the miner and cutter and deposit is the best one. Dispersion is greater than diamond and the beautiful color separation can be seeon on the microscopic views.
