This was again something of an experiment. I wanted to see how the turbine design would work in a square cut, when you're doing something new the only way to see how something will look is to do it. I was very pleased with how this turned out. The pattern effect works really nicely within the square shape. I named it "Origin" because of a certain metaphysical resonance I had when seeing the design for the first time. In the beginning everything began (begins) from a point and radiates outwards. This creates the "four directions" of north, south, east and west and is embodied in the four sides of the square. It's sort of a creation/origin event story captured in a gem. It's hard to explain in words, sorry about that. It's something that my mind intuitively grasps because of my life story and studies but like alot of things in life, it's hard to put down into words.

I wanted to see how the chrysanthemum would work in an oval shape so I cut one as an experiment and here it is. I knew that the oval shape would alter the pattern effect and I was very happy with the result. It reminds me of that carzy character in the "Ice Age" movies. If you look at the gem you'll see the "eyes" at each end. Something a bit different.

Comments : This is the first topaz cut in my new 'Cross Of Faith' design. I had this design in my mind's eye for a while and I decided to try and cut it in topaz to see how it looked. I think thats part of the artist's creative process... seeing something in the mind's eye and then manifesting it into physical reality. I am very happy with how it turned out. The cross is 'frosted' with the upright bar frosted on the pavilion and the cross bar frosted on the crown. This creates a really nice effect and looks really good. At night the cross really stands out in artifical lighting. The topaz is a nice bright silver white and this would make a totally unique and special pendant.

Comments : Now for something a little bit different. This is one in a series of platonic and archimedean solids that I am planning to cut. Not really sure that it could be used in jewellery, its more as a curiousity. For those of a spiritual metaphysical mind, it could perhaps be used in various meditations or some other similar exercise. I could see for example how if one was to meditation laying on their back, the dodecahedron could be placed on the third eye. I have noticed various cheap platonic solid sets for sale out there but they are mass produced, very inaccurate and the quality of the rock they are cut from is not the best. This dodecahedron is precision cut in clear O'Briens Creek topaz.

Comments : The history of topaz is a long and ancient one and the gem has long been used as an ornament and jewelry stone. The name "Topaz" is thought to come from the name of an island in the Red Sea formerly called Topazos but now Zebirget. Topaz was mined here on this island. Another possible origin of the name Topaz is that it comes from the Sanskrit word "tapas" which means "fire" or "heat". This could be due to the yellow/red colour that topaz sometimes occurs in.

Many people believe that topaz comes only in yellow and this is true, it does come in yellow. However fancy colors like yellow, reds, oranges and pinks are actually quite rare, so is the very beautiful natural blue. My personal thoughts on why yellow has become closely associate with topaz, in the same way that blue is associated with sapphire, is that in historical times the technology or ability to differentiate between types of stones was very limited. Yellow quartz, now known as Citrine, is quite common in many parts of the world and I believe that alot of yellow topaz was actually yellow quartz. Today we have the ability to tell the difference between the various types of stones but one still has to be cautious in the marketplace and buy from a reputable dealer as there is still the potential for confusion.

Topaz makes an ideal jewelry stone as it is hard and very durable. It cuts well into brilliant designs and becomes a gem that has lots of scintillation and "fire". If I was pushed to pick a personal favorite of all the gemstones, I would probably have to give
natural blue topaz the nod. It is a stone that I love to cut and the colour, though soft, is divine. Truly it is! The soft blue colour is for me, the most elegant of blues, soft and delicate, sometimes ethereal, sometimes icy like the blue in an arctic iceberg. It is cooling on a hot day, fresh and light and always cheery and pleasing. Each stone is unique in its coloring, some have more blue, some less. The colour is easily as beautiful as aquamarine and in truth, far better then the vast majority of aquamarine that is in the marketplace.

Sadly, with the advent of modern gemstone treatment technology, natural blue topaz has taken an undeserved fall from popularity. Irradiation and heating is now routinely used to change the clear silvery white topaz into a uniform array of vivid treated blues. These stones have the trade names of london blue, electric blue, swiss blue and sky blue. The colour is the same for each category and this is the material that you see in jewelry stores across the land. It is cheap and plentiful whereas the natural blues are scarce and relatively expensive. This sudden mass explosion of treated blues dealt the natural blues a blow and that is sad, for these natural blues are easily one of the most beautiful gems in the world of coloured gemstones. Blue sapphires might be the Queen of Gems, but if there is a Princess of Gems, she would be a natural blue topaz.
