Cognac Precision cut Cushion 6.63 x 5.4mm/1.31ct Songea (Tanzania) Sapphire Loose Gemstone

1 item left

This custom precision cut cognac-colored 1.31ct Sapphire from the famed Songea region of Tanzania is available for a custom-built ring by Nodeform Jewelry. This one-of-a-kind gemstone is an absolute stunner that glitters and pops with fire. 

The well-cut gemstone has a stunning warm cognac color and shows some color-changing properties. It turns from a beautiful orange and pink-bi-color in incandescent, to purple/pink with a green-yellow flash in daylight, to purple and pink in halogen, and golden orange in LED.

It just surprises you with its natural beauty in any lighting. Some color shift from one kind of light to another is one of the cool features of some natural sapphires.

Sapphire specification:

  • Mined Genuine Sapphire
  • Weight: ~1.31ct
  • Size: 6.63 x 5.4mm
  • Cut: custom long cushion cut
  • Treatment: None 
  • Color: warm orange with pink and purple

This stone would look great set sideways in Nodeform's signature FOLD semi-bezel ring setting available here.  Or it also looks stunning to set it with a North-South orientation in the double prong Ivy split shank ring setting as pictured. Other custom designs are possible. Just contact me to discuss. Due to the unusual cut of this gemstone, it does not fit into many of our other ring settings without some design modifications. Please allow extra design and fabrication time to provide a perfect fit.

Set in yellow or rose gold it will really highlight the warm fire in this stone. Set in white gold or platinum will provide a stunning contrast and make this stone pop. Your choice to select what you think fits best for your style.
