Iolite qualities and cuttings–
Iolite has two features – A violet hue derived from presence of iron and its Pleochroism optical property which can be seen easily by the eyes with no need of any magnifying loop. It is blue-gray, blue-purple and dark blue and somewhere colorless, which shows when you see it from different sides. We explained in our Tanzanite product page about the cutter’s challenge and when he/she cuts this stone, its the same way. The cutter tries their best to cut in a way that the grayish, yellowish, colorless and brownish hues don’t show through the crown or face. When you see a rough of Iolite as above, then it is very difficult to analyze the side for the best color and only experts know this. We have an 18 years experienced team for this Iolite gemstone cutting job.
When we talk about the treatment then Iolite is a completely natural stone without any enhancement. Iolite is mined in Mozambique, India, Sri Lanka and Brazil and other countries. A cordierite is typically an opaque gemstone and this quality is used in cabochons, while fine gem-quality Iolite comes in a transparent to a translucent quality. The cutting of Faceted Iolite Gemstones matters a lot, if its a shallow cut then it shows “window” and a deep cut reduces the transparency, so it should be cut perfectly in order to get a perfect transparency and color.
It has been a little difficult task for a normal person to distinguish among Tanzanite, Iolite and the other transparent blue stones. There is a simple trick, when you rotate Iolite then it gives a grey to colorless tint/hue. On the other hand Tanzanite gives a purple hue when you rotate it.
Iolite cuts and cabochons stones –
Mainly Iolite is cut in faceted stones because of transparency but the slight or weak colored material or “SI material” is used in cabochons. You can find 5 carats and below of Iolite stones without struggling hard but over 5 carat sizes are difficult to find and generally it ranges up to 10 carats. We have all regular to free size Iolite faceted and cabochons stones.
How to Identify Iolite?
Tanzanite and Sapphire quite resembles Iolite. The only way to identify the correct stone is the hue. First if the color is Sapphire Blue then it is Blue Sapphire, or if its violet-like blue then it is Tanzanite and if it is a light-blue with grey and colorless at some point, then it is Iolite. If we compare based on hardness then it is harder then Tanzanite and softer than Sapphire. A good quality Tanzanite comes in a vivid blue that color you cannot get in Iolite and Blue Sapphire. Another way is to see the size of the stone because in a vivid blue color, it is difficult to get a piece of Blue Sapphire and Iolite above 5 carats. Over 5 carats, Iolite and also Blue Sapphire come in included quality and Tanzanite can be found in clear quality easily.
