About Boulder Opal
Boulder Opal is the second most prized form of opal, after black opal. The name derives from the fact that boulder opal is found embedded in ironstone boulders. The opal usually forms as thin veins within these boulders, and most stones are cut to include some of the host ironstone matrix. Boulder opal is sometimes referred to as opal in matrix for this reason. Boulder opal is especially attractive because, like the black opal, it has a dark body tone which adds vibrancy to the play of color. Boulder opal also has a higher density because of the ironstone content, and can be more durable as well.
I have always been skeptical of ordering fine items online for fear of disappointment. Today, Thursday April 26, I received the blue sapphire which I ordered on Monday, April 23. Not only was I impressed with the rapid delivery of my sapphire, but I was very pleased with the way the stone was packaged and protected. The sapphire itself was far better quality than I had anticipated and it will make a beautiful centerpiece for the ring I'm having made. Thanks so much for the great experience...
