Next up in the auction block…. A magnificent 3.51ct pear cut fancy intense green natural diamond, this rare beauty is expected to fetch between $800,000 and $1,200,000!!. Fun fact for the day… a natural green diamond’s hue is generally confined to the surface and is rarely throughout the stone. They get their colour from radiation displacing carbon atoms in the crystal structure.

Spessartite GarnetsSpessartite Suite: (l–r from top row) 24.80-carat oval from Nigeria (Inv. #13832), 17.71-carat pear shape from Nigeria (#20423), 12.90-carat pear shape from Nigeria (#16043), 22.73-carat cushion from Tanzania (#21599), 12.71-carat round from Namibia (#1531), 10.46-carat oval from Tanzania (#21598), and 11.10-carat oval from Nigeria (#21569)
Spessartite draws it derivation from the type locality for the mineral, Spessart, in Bavaria, Germany. Simply put, this is an orange variety of garnet, but the terminology, deposits, and actual colors are far more complex. 
Spessartite is more of a mineralogical term for a specific chemical formula (Mn2+3Al2(SiO4)3) within the garnet group. The term spessartine is more often used in Europe but is synonymous with spessartite. Mandarin is a term inspired by the Namibian deposit producing more pure-orange hues. 
When the Namibian deposit came online around 1991, the color palette for fine spessartite changed. The material coming out of Marienfluss, Kunene Region was an electric mandarin-orange hue, with some minor pink or red secondary that made it seem very pure and intense. The only drawback to this material was that it often had fine needles creating a silky appearance.

Purple-Pink Zoisite from Tanzania
4.28 carats, 12.18 x 8.89 x 5.61 mm,
purple-pink zoisite from Tanzania. The Merelani mines have produced large amounts of blue-to-purple tanzanite since its original discovery in 1968. The mines also have produced gem quartz, diopside, prehnite and calcite. Occasionally pink and purple zoisite (often referred to in the trade as pink tanzanite) is unearthed in small, localized pockets, but production of these colors is very limited.

Spinels from Abroad
Spinel spectacle: Clockwise from top left, 8.07-ct orangey red Burma oval (Inv. #20439), 12.37-ct lavender Burma cushion (#20436), 7.11-ct pinkish red Tanzania oval (#20468), 1.8-ct flame red Burma cushion, 1.26-ct cobalt blue Vietnam pear shape (#20502), 3.73-ct cobalt blue Burma oval (#20467), 6.14-ct purply pink Tajikistan cushion (#17979). Center, 5.90-ct violet blue Vietnam pear shape (#20437).
The spinel family continues its campaign into the world as its color cornucopia and exquisite properties continue to impress. As the rarity and beauty of the spinel varietals disseminate, the collectors seem to be acquiring a taste for this rising phoenix. We in the trade have always had a love for spinels, but now it seems the secret is out. We can’t seem to keep up with the requests for fine reds and blues. So we are constantly scouring old collections and keeping an eye on material coming out of the major spinel-producing regions, mainly southeast Asia and eastern Africa.
