In stock


Large and unique, full face Blue Opal from Queensland Australia. This Boulder Opal is filled with dense blue specs of fire and never goes dim, it will be blue on all of its surface no matter what orientation or direction you view it from. Although impossible to capture for the camera, there is some green in this stone as well which makes it look just like a tropical sea. Already unique for its size and colour stability, this stone has another unusuall feature- it actually looks bettter in dispersed light, like on a cloudy day, which makes it an ideal gem for a country like Britain where we don't have direct sunlight for most of the year. This blue opal has a slightly convex face which will make it much more protected against the damage after setting in jewellery, as no part of the gem is going to be rised above the setting. Please note this gem is 100% natural, it is not a composite stone but a natural Boulder Opal.

Opal is a composition of silica and certain amount of water, usually up to 10%. Its internal structure was a mystery until the invention of electron microscope, which revealed a lattice like pattern of silica spheres arranged in more or less orderly fashion. That is the case for precious opal which dazzles us with its play of colour, which in turn is created when light gets scattered and waves interfere with each other. There are many varieties of opal with main sources being Australia, Mexico, Brazil and recently Ethiopia. Opal has amorphous structure and its hardness varies between 5 and 6.5 on a Moh's Scale. While wearing opal you should generally avoid, hard knocks, abrasion, immersion in liquids other than water ( household chemicals, oils etc.). To clean your opal it's best to use wet cloth or gently clean it under running water, you should avoid ultrasonic cleaners for blulder opals especially.

Pictures showing gems are many times their size and may show you more imperfections (inclusions, imperfections of cut and polish) than you will see while holding the same gem in your hand. Certain gems like opals do not look the same under different lighting conditions or from all directions and in such case we chose the best shots to show potential of the stone.
