Sapphires and Rubies

  • The Sapphires that we have come from Eastern Ontario. They are the first sapphires to have ever been discovered here. Further explorations will be required to determine if there are more sapphires in the area, or not. The sapphires found so far are yellow, clear, grey, green and pink. Some are very light blue when polished. We have yet to find any deep blue ones. We also have found one very, very large ruby. The stone weighs 27.43 grams, 137.15 carats. This makes it one of the largest raw Rubies on the market in the world today.  One side is yellowish as there is a second crystal twinned on the side that is part yellow. Some of the sapphires re very large as well. the largest is over 160 carats making it one of the largest sapphires in the world right now. As is true of all the specimens found at Ontario Gemstones all are rigorously tested and certified and guaranteed to be pure natural Ontario Sapphires. The hardness is 9.0 and the SG is 3.99. Most of the rough stones are spindles, which is a dead giveaway for corundum minerals. A few specimens are selected below for your viewing. All Sapphires and Rubies in general have inclusions and striations. These are natural stones. and so too have inclusions in them and striations. Sapphires and Rubies are generally heat treated to deepen the colour and remove the inclusions and striations. We can provide heat treating if desired.
