Rough stones are a raw form of crystals that are found in nature or are grown in lab, from which gemstones are cut from. It maintains an unpolished appearance.They especially come in use in jewellery crafting.
Among these rough stones, we have come up with a great variety to meet your needs and specifications.
Cubic Zirconia Rough stones come in a variety of colours for you to get according to your preferences. Be it lavender, red, yellow, orange, violet, pink, champagne or pink rose, blue, Sapphire, brown, teal, emerald green, blue topaz; you can get it all and many more. Notably, it has a mix of multiple oxides involving silica, zirconia, zinc, alumina, magnesium and lithium oxides.
Besides, it has a lower sensitivity and cuts. Hence, this has been extensively popular in jewellery making like pendants, earrings, etc.
- Gravity: 5.7
- Refractive Index: 2.15 to 2.2
- Hardness: 8.25 to 8.5
We supply the Cubic Zirconia Rough stones of the best quality in a wide variety of colours.
Hydrothermal Quartz Rough Stones
The Hydrothermal Quartz Rough stones are also available in many variants. You can find them in smoky, Amethyst, peridot, citrine, white and blue shades. In addition, they can be custom-made in lighter, medium and darker shades based on the choice.
Along with this, you can even customise the size of this rough quartz stone. Hydrothermal Quartz Rough stones hold the silicon dioxide chemical composition.
- Specific Gravity: 2.65
- Refractive Index: 1.543 to 1.545
- HARDNESS: 7
Glass Rough Stones
Glass rough stones have hexagonal and hexagonal prisms crystal design with an indistinguishable cleavage pattern. Their transparency also transforms from high to opaque.
Besides, rough glass stones are chemical composition of aluminium beryllium silicate. Accordingly, their birefringence lies between -0.004 to -0.005. Additionally, one of its main features is vitreous lustre.
- Density: 68 Ð 2.74
- Refractive Index: 64 Ð 1.596
- Hardness: 7
Nanosital has a scarcely unusual strong lustre that is relatively conventional to Cubic Zirconia.
The higher melting point during the creation enables the use of colour variants in the casting of lost wax.
Nonetheless, the colour play of these rough stones is extremely impressive. Their vast colour ranges from transparent to colourful shades are unmissable. In addition, they come with complete correspondence with absolutely no internal inclusion makes it so popular in the jewellery industry.
Again, their hardness index is also higher than that of glasses. So, their hard index allows making durable jewellery without losing the original appeal. This is why Nanositals are so much readily accessible for use as rough jewel material.
- Specific Gravity: 3.5 to 4
- Refractive Index: 1.65 to 1.7
- Hardness: 7
Hydrothermal, Pulled Czochralski
Hydrothermal, Pulled Czochralski rough stones are products of lab-creation using the hydrothermal process. They are synthetic stones that researchers create in the laboratory mimicking the natural composition.
Also, with their uniaxial optical character and indistinguishable properties, they are one of the most popular rough stones in the market.
Hydrothermal, Pulled Czochralski rough stones are available in multiple colours with flexible cuts. Consequently, they are greatly compatible with other assortments of jewellery compositions.
- Specific gravity: 3.01 to 3.06
- Refractive index: 1.614 to 1.666
- Hardness: 7.0 to 7.5
- Birefringence: 0.014 to 0.040
Flame Fusion rough stones undergo a Verneuil process to create various corundum ruby, sapphire and more. The primary method of forming flame fusion stones comprises the melting of finely powdered elements used as oxyhydrogen flame.
Hereafter, they transmit into the crystallisation of the melted droplets into the boule.
We offer high-quality rough stones and a large variety of rough stones in different colours and compositions to meet your requirements. So, customise them in the preferable size and colour.
