Thickness - 3.8 mm (thickest spot)
Shape - Freeform Kite-shaped
Code OPL155
This is a very bright to intense opal. It has a series of beautiful broad-flash patterns that change color and shape as the opal is turned or rotated. The largest portion of this opal is an intense green that changes to cyan and blue when it is moved. There also are a number of areas that usually stay very bright blue or intense cyan. The depth of precious opal is almost the full thickness of this opal. This yields a series of three dimensional effects as the opal is moved and the colors shift.
The face and sides of this opal are perfect and the shape is an interesting free-form kite-shape. There were a couple of cutting marks left on the bottom that have no effect on the face of the opal. This opal will make a lovely pendant or possibly a ring.
This opal was cut from a white base rough opal with darker backing matrix. It was mined in the Coober Pedy region of Australia. There were two bright precious opal bands in the original rough stone. OPL156 was the other layer although it is not nearly the equal of this gemstone.
Retail Value: About $125 to $175 per carat ($540 to $750).
Starting Price (Until the photos are made): $145.

Thickness - 5.8 mm (thickest spot)
Shape - Freeform Long Shield (or Cut-off Oval)
Code OPL158
This opal has a thick precious layer with intense green-gold fire. When the opal is moved, the fire appears to move around within this layer. There also is a very intense yellow-gold and a very bright cyan/blue broad-flash fire in this opal. The 3-D effect of fire is quite attractive. The precious layer is thick enough that it could have been split into two opals, but I do not like to do that.
Below the grey crystal precious fire layer there is a base of dark grey (semi-black to black) that gives the fire contrast. To preserve the contrast, this opal is cut a little thicker than it otherwise would have been. The quoted prices reflect the fact that the opal has been cut thick.
This gemstone should be a pendant stone with the flat part of the shield on the top. In that position the fire is the brightest. Many are not familiar with the fact that opals with a thick fire layer often have a "best" angle of display.
This opal was cut from dark grey rough opal that was mined in the Mintubi region of Australia. Many of the worlds best green/blue opals come from that region.
Retail Value: (Reduced by 20% to account for the thicker base) About $100 to $150 per carat - Difficult to Estimate ($750 - $1100).
Starting Price (Until the photos are made): $145.

Length - 14.5 mm
Width - 6.0 mm
Thickness - 4.0 mm
Shape - Long Free-form Oval (Almost Pear-shaped)
Code - OPL148
This opal is covered with very bright blue pin-fire sparks along with some green (especially at an angle). The base is a dark-grey called a semi-black. The contrast between the base and the sparks is very good because of the opaque black base. The unusual base is described fully in the next paragraph.
The base and "structure" are rather unusual. First of all the bottom of the opal is a course white almost sandy matrix. Above that layer is a layer of dark black that makes the colors of the sparks stand out in high contrast. The precious opal layer is a medium-to-dark grey. One tiny piece of the sandy base matrix is visible on the side of the opal but not directly from the top. The overall effect of this opal is almost like a natural doublet opal, but it is all sold opal.
This opal was cut from rough opal that was mined in the Coober Pedy region of Australia. In some ways this opal is more similar to that opal dark-grey opal found in the near-by Mintubi region of Australia.
Retail Price: About $90 per carat ($180). (This estimated price per carat has the thicker base and the matrix inclusion factored in.)
Starting Price (Until the photos are made): $29.

This opal has a series of very bright green and bright blue flashes. From some angles this pin-fire takes on a cyan color. A lot of color passes through this opal especially in bright light. This would make a nice ring or pendant stone.
This is an interesting opal with a grey base. It was cut from the grey base opal of the Mintubi region of Australia. It was cut a little thinner than it should have been. There is a cutting mark left on the bottom center that will show through the stone if it is held directly in front of a bright light.

This is an attractive white based opal. It was cut from the white opal of the Coober Pedy region of Australia. There are two white inclusions that are visible when looking through the opal into a bright light. These are no problem in the opal, and under normal light they are mixed with a yellow-orange fire of their own.

This opal has a series of bright to moderate blue pin-fire. As the opal is moved, different areas of the surface pin-fire come into view. This opal was the second band of precious opal with OPL155 above. While this opal is not nearly as intense, it has a charm of its own.

This is an unusual opal. The rough stone had an attractive bright pearly-blue sheen/fire. When we were planning how to cut this opal, we decided we liked it just as it was. The sides were cut to a reasonable shape based on the original stone. The face of this opal has a rolling slope with the natural bright blue on the surface. We decided not polish it further. Some things are best left alone.
This is an interesting opal with a grey base. It was cut from the grey base opal of the Mintubi region of Australia.
