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 purchased many gems from this company and am always very pleased with the quality of gems and their cuts. Each time I am pleasantly surprised by how quickly I receive them! I will order again and again. Always very happy with them!!
I enjoy this newsletter for the information and descriptions of the gems as well as all the history and myths surrounding the various gems. This newsletter makes me wish I was young so I could study to be a gemologist!
Excellent will be returning to make more purchases! Ordered one sapphire and one tourmaline, both arrived within 3 working days and appeared to be the exact stones shown in both pictures.Smooth transaction and very well set out website, easy to use and informative. Will definately be buying more gems from Gemselect. Gems are a little darker than they appear on the website.
