  • Aquamarine is probably the most popular blue, bluish green to greenish blue coloured gemstone, being a beryllium and aluminium-bearing species of the beryl group, also named beryl as a mineral. Other gem varieties of the same mineral include emerald (green, caused by chromium and/or vanadium); green beryl (green, coloured by iron); morganite (pink to orangey, caused by manganese; heliodor (yellow); golden beryl (golden yellow); goshenite (colourless); red beryl (red, caused by manganese).
Aquamarine is not only an important coloured gemstone, but also a popular collector’s mineral specially in euhedral specimens (meaning with well developed crystal faces) typically in terminated six-sided prismatic habit. One of the most notable occurrences is the Medina pegmatitic field in Minas Gerais, Brazil, where clear gemmy crystals are known to occur with typical surface etching marks of great geometric visual impact.

  • Its another #transformationtuesday 😀 this Sapphire piece of rough was long and narrow and limited the kind of shape that could be cut from it, but I loved the parti colours in it so I wanted to accept the challenge! I was also curious as to how the colours would turn out in such a long stone, often a darker colour at one end will reflect down to the opposite end, and with such a pale middle to the stone I was curious if we would see 3 sections of colour. The result was quite pleasing, although it has a fingerprint inclusion right across the centre of the stone, I like the way the colours graduate down the stone from dark blue, to yellowish green, to blueish green at the tip. This is an unheated Sapphire, if the stone was heated then the results could look different again by lightening the dark blue area #tatumgems

  • At Gem-A we prefer our Blue Mondays aquamarine...💎 We love the pale blue colour of this faceted aquamarine - even though it might be a bit rough around the edges! 
We think it's really important to show our students gemstones in a wide variety of shapes, sizes and quality (including those with a few fractures) to ensure that they are familiar with the vast range of specimens that they are likely to see in the gem industry.

And, personally, we think there is beauty to be found in every gem! 📷 Henry Mesa, Gem-A.

  • Rubellite is the collective trade name given to pink tourmalines. In scientific terms, tourmaline is not a mineral species but rather a vast and complex mineral super group that includes a few species with gem potential and pink has been so far reported in elbaite (the most common), fluor-liddicoatite and rossmanite. This means that rubellite is not quite a varietal name but rather a colour-related trade name that is synonym of "pink-coloured tourmaline". In the jewellery trade, things tend to be kept simple and the terms “pink tourmaline” or “rubellite” are used interchangeably rather than the complex mineralogical terminology that needs advanced chemical analysis confirmation made in a laboratory.
In the image, the famous 260.86 carat pink tourmaline carving (4.0 x 2.7 x 2.3 cm), possibly from Burma (Myanmar), set in enamel-decorated gold from the Imperial Russian treasures. This rubellite has a rich history in Europe since the 17th century when it belonged to the wife of Charles IX of France, to Rudolf II of Bohemia and to Queen Christina and Gustav III of Sweden who offered the gem to Catherine II of Russia in 1777. It is currently on display at the Diamond Fund of the Kremlin, Moscow © Gokhran of Russia

  • The wonderfully creative and talented Susannah Gai has done some superb carvings of several of our recently posted West Australian chrysoprase material. Susi will be with both the ever effervescent and irrepressible Sarenah and I this year at both our venues in Tucson (details coming this week).
Please drop by, say ‘Gidday’ and introduce yourself to us there, we’d love to chat and to introduce you to our latest West Australian gem material.

  • Finally arrived!🙏🏻🌟💎 Новая книга @vlad_yavorskyy, полностью посвященная благородной шпинели месторождения Кух-и-лал. С VIII века небольшой поселок в Горно-Бадахшанской области (Таджикистан) известен на весь мир ценными кристаллами шпинели розового, розово-фиолетового и даже красного цвета- палитра, по которой опытный глаз практически безошибочно определит origin (происхождение) камня 🧐🔍
Место, которое обросло легендами и в новейшей истории. И про то, как при вскрытии из «магалов» ( гнезд высокой концентрации кристаллов) буквально сыпались  драгоценные камни; и про уникальный кристалл ювелирной шпинели размером, на минуточку, с голову человека и весом более 5 кг ( найденный Яковом Гуревичем в конце 80х), которому не нашлось места в союзных музейных фондах и он бесследно исчез в Таджикистане во время гражданской войны в 90х.

Потрясающие камни, пейзажи, иллюстрации, фотографии. И самое главное, такие знакомые памирские пейзажи и  горы, суровые и холодные, на фоне ярко-синего неба, словно с картин Рериха. 🗻🌏☀️ .
Черно-белые зарисовки из жизни памирцев, Хорог, Пяндж, базары и дастарханы -  вот где-то там севернее Хорога, за перевалом на 3000 м, 
базовый лагерь Койтезекской партии, геологосъемочная экспедиция и мои школьные каникулы ☀️⛺️🎉
.
Замечательная книга. Очень теплые воспоминания.
В общем, вернусь обязательно👌

  • Everyone loves a good #transformationtuesday so I thought I’d share this Tourmaline fresh off the dop! First stone finished in 2020 😁 it turned out such a gorgeous pink sunset colour and weighs a nice 1.29ct down from a 4.2ct piece of rough. Unfortunately even though the shape was followed closely from the piece rough there was an inclusion that needed removing from the crown so I dropped the angle lower to cut a clean stone rather than to save weight and risk the inclusion chipping later. On most stones the average weight retention will be between 25-38% if cut to good proportions to optimise the light reflection and refraction within the stone 😊 this Tourmaline had a 31% weight retention so its still nicely in the ballpark #tatumgems

  • “Ooooh…let’s get this in the winter sunshine!” A beautiful deep lilac crystal of ‘kunzite’ with lovely pleochroism from the Mawi pegmatite, Nuristan, Afghanistan. Stand out for me is the incredible lustre with depth of colour, even though the crystal is etched - so typical of this locality. As we know when crystals grow from solution, we not only need the right ingredients but there is usually a pretty narrow range of conditions to allow growth and indeed conditions in place to continue for their ‘survival’. Many crystals show etch pits were crystals have dissolved, the reverse of ‘crystallisation’ where anions and cations are removed from the surface into a solution, creating other minerals or being removed from the system itself. Recently, a lot of work has been done on dissolution (natural and laboratory) as its important in understanding reactions important in geochemistry. It is fundamentally all about the energy, where the underlying structure is strongly bonded, dissolution is slow, other weaker areas, defects and grain boundaries it is faster. Here the top face is obviously dissolving fast producing these lovely ‘triangular’ or diamond shaped sculptural deep ‘hillocks’, quite similarly seen when other monoclinic minerals like orthoclase dissolve. Looking at this gemmy ‘wonder’ is beautiful the end result of a lot of energy transfer and subsequent reaction!  Such a pleasing colour don’t you think? @fineartminerals #wow #minerals #gems #mineralogy #crystals #crystal #crystalgrowth #chemistry #science #education #kunzite #lilac #amazing #gemmology #dissolve #rockhound #fineminerals #artistic #sculptural #natureart #amazingnature #colourpop #wellbeing #settingsun #beautiful #iwantone

  • Ethiopia has been known in the gem industry for the opals and hydrophanes from Shewa and Welo, since around 1994 and 2008, respectively. In 2016, a few years after sporadic findings, emeralds started to be reported in commercial quantities from the south district of Seba Buru near the town of Shakiso. These mica-schist type emeralds are predominantly light coloured with eye-visible inclusions, but fine examples of good colour and clarity in significant sizes have been reported. It has been also reported that in the finest qualities many do not require the traditional fracture or fissure filling treatment to enhance clarity. The best material compares with fine Colombian emeralds but differentiation might be challenging if only classic gemmological methods are considered (e.g. inclusions), requiring advanced analytical methods (e.g. LA-ICP-MS) to support an origin opinion.
In the photo, Shakiso emerald rough crystal and cut gems from the Hallo mine owed and operated by the Bu'a Obsa Mining Association, Ethiopia. The colour, clarity and brightness of these fine cut stones has put Ethiopian emeralds in great international standing for both connoisseurs and the public.
