3.75 ct Blue Round Cut Natural Unheated Sapphire

$0.00 AUD


Almost 4 carat unheated natural round Ceylon sapphire.   

Astounding size at 9.2mm diameter in a round sapphire. A rare size to come in round sapphires. 

Somewhat "windowed cut" which means loss of light through the middle of the gemstone without returning to the eye. Nothing is absolutely perfect about this natural gemstone but it faces up spectacularly. Rich medium blue colour, the size and the sparkle all works very well together. We cannot wait to see this gemstone set. 

Unheated means the sapphire has not had any treatment including heat treatment to enhance its colour or cleanliness. Sourced from Sri Lanka, this gem is natural earth mined. 

Create one of a kind round cut sapphire custom engagement ring with this natural loose gemstone. 

Round Ceylon sapphire bespoke engagement ring ideas;

  • White diamond halo yellow gold ring with the sapphire being set in bezel setting could look stunning. 
  • How about a pastel pink diamond or pink sapphire halo in yellow gold?
