| A number of lots of very fine dioptase had recently come to America from this locality. |
|
| For digital photography, SoLux bulbs are perfect, yielding accurate rendition of difficult-to-photograph minerals such as dioptase and azurite. |
|
| Tantara dioptase occurs well crystallized with quartz, plancheite, shattuckite, fornacite, and chrysocolla. |
|
| The mine is well known for the rare secondary copper minerals that occur in the lode, including paramelaconite, cuprite, malachite, and dioptase. |
|
| The color of dioptase does not photograph well and must be seen in person to appreciate. |
|
| The Algomah mine is best known for lapidary material and copper-bearing microminerals, including plancheite, kinoite, dioptase, azurite, and atacamite. |
|
| We had traveled across twelve time zones and back in time at least fifty years to get dioptase at the source, but our timing was as poor as the specimens. |
|
| Many of the best Tsumeb cerussite, dioptase, azurite, smithsonite, and other specimens passed through his hands en route to some faraway collection. |
|
| Low blood pressure can be treated here with a light green stone such as chrysoprase and high blood pressure can be treated with a dark coloured specimen such as dioptase. |
|
| Dioptase is a very beautiful mineral and it is one of the few minerals that can challenge the peerlessness of emerald's deep green. |
