PARAIBA BLUE TO ELECTRIC TURQUOISE GREEN

Lot: Tourmaline-290

STONE 1

   
7.38 Carats & 8x9x10 MM. This is a nice and blocky crystal section shaped for slightly below average yield if cut for clarity. Our personal recommendation would be a Trilliant or an Emerald Cut as it is practically preformed for those shapes. The color is a lovely Electric almost Paraiba Blue and it is the best of the three stones as far as color goes. The stone looks like it is capable of cutting eye-clean with a little planning and effort; however, yield will probably be slightly below average if you are aiming to cut the cleanest stone possible. Please note that the stone does have some surface inclusions and feathering as well as a veil at one end (the latter of which should facet out with proper orientation). These can be seen to a degree in the first and third pictures above. The first picture shows the surface inclusions (some of which extend a bit into the crystal) and the third picture shows the veil that will need to be faceted out towards the right end. The veil shouldn't be a problem to remove whereas you will have to plan more for the surface inclusions on the periphery of the crystal. These inclusions are common for Tourmaline in general and are confined to the rind or close proximity to it for the most part. We anticipate that all inclusions can cut out with normal faceting and a little planning; however, yield will be higher if you planned for the larger stone that may have some minor inclusions that would most likely be hidden under the crown facets.

STONE 2

      
9.51 Carats & 7x8x15 MM. This is a nice and blocky crystal section shaped for average yield if cut for clarity. The color on this is a lovely Neon Minty Blue. Our personal recommendation would be a Rectangular/Emerald Step Cut as it is practically preformed for that. The stone looks like it should cut eye-clean to very slightly included with a little planning and effort. Please note that the stone does have some surface inclusions and feathering. These are common for Tourmaline in general and are confined to the rind for the most part. There are some inclusions off towards one end of the stone that will force you to sacrifice some weight for an Eye-Clean or better stone; however, yield should be around average if you choose this route whereas the weight would probably be slightly above average if you choose to facet the larger stone. We anticipate that most inclusions on the periphery should easily cut out with normal faceting; however, you will have to take a few minutes to plan the orientation of this stone to insure you get an eye-clean or better finished gemstone.

STONE 3

   
14.23 Carats & 5x6x33 MM. This is a nice and blocky crystal section shaped for high yield. The color on this shifts from a Neon Green or Sea-Foam at one end to a more Bluish or Turquoise Green at the opposite end. The stone looks like it should cut eye-clean to very slightly included with a little planning and effort. Please note that the stone does have some minor inclusions and feathering primarily concentrated towards the center of the stone (these can be seen in the second picture). These are common for Tourmaline (particularly bicolors) and we anticipate that most inclusions should easily cut out with normal faceting. The inclusions toward the middle will clearly be visible in the finished stone should you aim to cut a single stone out of this and we would ideally suggest two stones that are roughly of equal length. If you were to cut this into two roughly even sized stones you should cut eye-clean or better finished gems.
