A medium toned purple with significant flaws.#281
This standard round brilliant is typical of the type of cuprian tourmaline that became available after the world was introduced to its beauty. About half of it is clean and flashy while the rest is so included that it obstructs … Continue reading

Copper and Manganese made a Lady of Her, round#271
I am not a great believer in luck, but there are times when you’re game plan works out. My game plan with the collection was not to secure the best investments or even the prettiest tourmaline, but to chase color. … Continue reading

Significantly included, Laurellite, cuprian, round, Mozambique#947
This standard round brilliant has a nice purple color in daylight, but its flash is significantly lessened by it feathers. I say daylight with the purple, because it is a Laurellite. Laurellite is a name I gave to a new … Continue reading

Included, Oval, Laurellite, Cuprian, Elbaite from Mozambique.#945
This oval was actually the first Laurellite that I cut. It is not as colorful as her sister #944, since her color change goes from purple to more of a grayed blue, but she set me up to take action … Continue reading

A very bright, non dichroic, medium toned, emerald cut. cuprian.#438
This pastel green with a touch of blue, emerald cut stands out in the tray of green emerald cuts. It has a great medium tone and a very bright eye clean look. I discovered that this gemstone has copper in … Continue reading

Smaller emerald cut with dichroic green and yellow green color.#434
This emerald cut has normal angles and an open yellowish green c axis. The a/b axis is a medium green and the overall tone level is moderate. It appears to be eye clean and with fine crystal. It came from … Continue reading

Open ended bright, medium toned, green emerald cut, Mozambique#431
Looking at this bright medium toned emerald cut reminds me of my problem with propagating flaws in the green Mozambique material I got about ten years ago. This gemstone has a quite visible, residual, radial flaw flashing at me. I … Continue reading

Lightly included, pastel yellow washed with green, oval. cuprian#419
This is another gemstone that I did not buy as cuprian, but my spectroscope uncovered the proper absorption curves. It is very clean for a cuprian tourmaline from Mozambique, with only a very few light inclusions that do not effect … Continue reading

Included purple oval with blue areas, Mozambique, cuprian#1192
This oval is pretty heavily included and the inclusions do effect its crystal quality and flash. Still it has the rare color purple and the added interest that it has blue areas in the gemstone. This stone pushes the cleanliness … Continue reading
Gray with blue flash round, Mozambique#1185
The purchase of the rough for this standard round brilliant shows a bit more discipline on my part than my earlier days. The dealer had gotten a lot of a tourmaline with a different color that is never stated. It … Continue reading

Included and flawed, but still a laurellite, cuprian, Mozambique#1164
The list of problems in the title makes this stone sound worse than it looks. The flaws are not under the table and the inclusion/poor crystal is not bad enough to stop the standard round brilliant from flashing. So this … Continue reading

Medium toned purple with a bit more pink round cuprian.#43
The rough, for this standard round brilliant, was probably heated to lighten its original dark reddish purple color. The heating gradually reduces the reddish component in the color. This medium toned, lavender pink round is eye clean and with fine … Continue reading

A medium tone purple with pink passion, round, cuprian#42
This standard round brilliant was probably heated to lighten its original, dark reddish purple, color. The dark reddish purple tourmaline was the only really clean material, originally found at Mavuco, Mozambique. This excellent example of purple tourmaline with a … Continue reading
Lightly toned well saturated lavender oval, cuprian#41
The rough for the lightly toned lavender was cut from a large dark purplish red nodule that had been heated to lighten it. It would have probably gone completely light blue if the heating continued. The blue is from … Continue reading
Medium toned, lightly included lavender droplet of color, cuprian #11
I love lavender tourmaline and can turn a very deaf eye to their inclusions. But with this standard round brilliant I don’t have to. It has some fine scatter, a but it is pretty transparent and flashy. The color has … Continue reading

Cuprian, medium toned, shift blue green round.#138
The top grade cuprian tourmaline that came out of Mozambique can be much larger and cleaner than the vast majority of Paraiba material from Brazil. But in both deposit, included material represented the vast majority of the production. I lowered … Continue reading

Slightly included, nicely saturated, yellow green, cuprian, droplet of color.#174

Cuprian, Purple droplet of color from Mozambique (included)#630

Magnificent bicolor with yellow crown and rust culet, orange round. Del Delgato#791

Snappy, sassy, cuprian, pinkish purple, but still lightly included oval#549
When it comes to cuprian tourmaline with a great pinkish purple color, I am very forgiving with cleanliness, but in this case I don’t really have to be. It has a moderate tone level, which is beautifully complemented by just … Continue reading
A medium pastel blue with a touch of gray oval cuprian#539

Copper and Purple hand in hand, round#281

A lighter lavender with a selection of moderately light inclusions, round
Lavender, in the words of a poet, is copper’s sweet song of seduction in tourmaline. It seduces me into accepting flaw material that would be questionable in other colors of tourmaline. And when I am reward with an included gemstone, … Continue reading

Favorite green in the collection is a fighter, round.
Now to be the favorite green in this collection is saying something and it did not come easily. I purchased the rough for this gemstone well before copper was discovered in tourmaline from Mozambique, in “Laurellites” I supplied the GIA. … Continue reading
