In fact, black diamond tends to have a more metallic reflection than spinel and is harder on the Mohs scale (10).。Due to the difference in hardness, Spinel is much easier to manipulate and is most commonly seen in faceted cuts – square, oval, pear, cushion, and intricate round cuts are often created with black spinel gemstones. 。Spinel stones that naturally feature asterism are cut en cabochon to enhance the star-like look of the stone.。Spinel stones can easily be cared for due to their hardness and durability, polishing will not result in scratches on the surface of the stone due to its high level on the Mohs scale.。 To clean the Spinel stones you’re working with, simply use a soft cloth along with soapy water and remember to rinse thoroughly to remove any soapy residue. 。Cleaning with an ultrasonic cleaner is not recommended, as is the case with most other gemstones.。 And when it comes to storing your newly created pieces, try to store each one separately with a soft cloth to avoid any scrapes or scratches occurring if the stones are in transit or 。Edges under the polished, neat chamfer on the underside, back side glossy.。Cabochons do it myself, giving everyone special attention! Also I can make the necessary shapes, sizes, sets. All the cabochons do without a backing.。 For me, working with gemstones, not just work, as for those who produce polished stones, this is the whole universe, which shone all life!。 you can write to me: WhatsApp, Skype。send a cabochon video。General experience in stone processing more 20 years.。From the age of 7, his father taught the basics, and at the age of 10 he carved a stone carving, sharpened balls, complex table sets and boxes.。Of these, the professional experience of cutting precious and colored stones is 12 years.。Achieved the highest quality polishing, perfect symmetry and high precision in the manual production of cabochons with different and complex composite minerals, where the difference in hardness varies from 2 to 9 on the Mohs scale.。 I make all the tools myself, and find minerals every year, in the summer season, in the mountains of the Kola Peninsula and North Karelia.。 Participated in about 100 mineralogical and jewelry exhibitions in Russia, which are international.。And also participation in 2 mineralogical exhibitions in Finland and Sweden.。Participation in the festivals of art spaces such as Heat of the North, Solar Sister, Chill Out Planet with the creation of "Fantastic Stones" space on them.。Took part in dozens of handmade fairs.。 Masters from more than 25 countries use cabochons made by me, in creating high-complexity ornaments of such materials and techniques as beadwork, wire ornaments, sutras, macrame, jewelry made of genuine leather, jewelry art.。Hundreds of craftsmen want to cut stones preferably from me, knowing that I can make the highest quality on their sketches to within a fraction of a millimeter.。The color may vary slightly depending on the graphics card settings.。return the goods at the expense of the buyer.。
