After being a gem cutter for 24 years I have a good eye for stones that stand out and deserve special attention. Any and all warranties are between you and the seller. I hope you appreciate my perspective.
Natural Swiss Blue Topaz 12mm x 10mm Elongated cushion with a checkerboard crown. Weight 7.0 ct AAA quality. This stone was irradiated to bring out the blue color. Topaz is a hardness of 8 on the Moh’s hardness scale and wears very well. This stone requires diamond paste to polish and the polishing process is time consuming. I love topaz for it’s beauty and durability. This stone will give you years of pleasure. http://amzn.to/2fuIvrX
Amethyst All natural 10 mm square cushion. AA quality. Weight 3.95ct. Heat treated for clarity and color. Amethyst is a member of the quartz family and is a hardness of 7 on the Moh’s hardness scale. It wears well and is a great accessory for purple clothing. The February birth stone and a great stone for starting your collection. Amethyst is one of the first stones I ever cut.http://amzn.to/2edpEzz

Tanzanite Cabachon Please don’t consider this to be a lowly stone because it’s not faceted. This cab is a great color and a real “looker”. A great size: 18.5mm x 14mm x 10mm. You won’t have to squint to see this one! African of course; and all natural. Oval shape. 23.45 ct. Good quality. Cut in Brazil. Nice luster.http://amzn.to/2edm2xC

Tanzanite A gorgeous violet blue oval from the famous “D” Block mine in the Merelani Hills of Tanzania. Some of the best stones have come from this mine. This stone is IF quality. Internally flawless and did not need heat treatment. Out of the ground in this beautiful color with no brown in it! 8 x 10 mm Weight 2.74 ct. A hardness of 6-7 on the Moh’s hardness scale. I have recut several tanzanites for customers that wore them down in rings. Because this stone is IF and not even heat treated I would not recommend it for a ring. Put it in a box for your collection or a pendant. http://amzn.to/2fiM5h
Andalusite is a semi-precious gemstone that was originally discovered in Andalusia, Spain. Hence the name. After the original discovery more deposits were found in the United States, Brazil, and Sri Lanka. Brazil being the main source today. When faceted it is quite beautiful and it can show three different colors. This ability is referred to as pleochroism. Colors are olive green to flesh tones and red. Also yellow to green to red. It has a hardness of 6.5-7.5 on the Mohs Hardness Scale. This makes it suitable for jewelry with one exception. It is slightly brittle and when in rings you need to be very careful. I would not recommend it for daily wear. A pendant or earrings, or a set with pendant and earrings is safe to wear without breakage. Faceted pieces usually weigh between 1 to 2 carats. Larger pieces do come along, but they are rather scarce these days. Expect to pay several times more for 2.5 carats and up. Andalusite is in my opinion very affordable and it would give you something different that you don’t see every day. I have included some photos that might give you wardrobe ideas if you wish to have the stone set.

This is the first post of what will become a series of posts informing you of various gemstones that you may not be familiar with. All lovely stones that you can add to your collection. I will also include well known gems and try to make you aware of some variations not common in the market place. For example: You may not be familiar with the word corundum. Corundum is the gemstone family name that includes sapphire and ruby. Till next time; stay well and happy!
Today I’m going to talk a little bit about the grading of colored stones. The different gemological laboratories all have a grading system similar to that of diamonds. Color, clarity, cut, and weight are the main concerns. It takes knowledge of the system and experience to be able to understand the complexity of their systems. In short; it’s difficult! It’s broken down into 3 “types” of gemstones first. Then there are clarity gradings, grading for different shades, and color saturation. 50% to 70% of the value is based on the color. A stone with great color and inclusions could be worth more than a stone of better clarity. If the stone is eye-clean; which means you can’t see any inclusions with the naked eye; you will be happy with the stone. I overheard a customer at a gem show talk about “Killer Color”. He was correct. The most important thing is color. After that you want a good cut and polish. A symmetrical stone. Nothing lopsided. Buying on line today is safe and reliable. Just make sure that the dealer certifies the authenticity of the stone and guarantees that it is natural. Not man made. Make sure the return policy is liberal so you have time to inspect the stone and truly decide that you are happy with it. Look at it often over a period of a few days and think about how or IF you want it set. The selection on line today is truly wonderful. Enjoy looking. You can spend hours just looking without the pressure of a sales person. It’s a virtual museum of beautiful gemstones!
