Materials

Joshiny's top reasons for choosing them are: reduced environmental impact, they can be produced by a lab, and although the price is more affordable compared to natural, it's still comparable to natural jewelry in terms of beauty.

Gemstone

Our laboratory gemstones are partially or completely manufactured by artificial crystalline or amorphous materials, the physical properties, chemical composition and crystal structure of these materials and their corresponding natural gemstones are basically the same.
For example, synthetic ruby and natural ruby are both chemically composed of Al2O3 (with trace elements of Cr), and they have the same refractive index and hardness.

Zircon

We use synthetic cubic zirconia, refined by hand in a predetermined process under specific conditions. The chemical molecular formula is ZrO2. It has a refractive index of up to 2.17 and a dispersion of 0.06, which is very close to that of diamonds at 2.42 and 0.044, and the high dispersion, in particular, results in more brilliant colored flashes in the finished milled gemstones. It carries no impurities and is as transparent and clear as diamond. Synthetic cubic zirconia has a Mohs hardness of 8.5, compared to 10 for diamonds.

Silver

 

 We use 925 Sterling Silver, which is the industry standard in the United States and most world markets. Our products are made from 92.5% sterling silver, a highly durable material that is ideal for everyday, long-term wear.
We work with quality suppliers, and more than 60% of our sterling silver is refined from recycled silver jewelry. This is part of our effort to reduce our environmental impact and improve the traceability of precious materials throughout our supply chain.

Rhodium

 

We will plate a thick, long-lasting layer of rhodium over high quality silver. Rhodium is a rare precious metal. It is a silver-white metal and chemically stable. It is corrosion-resistant and has a good luster, and the plating is strong and wear-resistant.
After rhodium plating, silver jewelry becomes more lustrous and resistant to wear and oxidation. If the silver jewelry is properly preserved, it will not oxidize for two or three years.
This process extends the service life of the jewelry and makes it more environmentally friendly.

Titanium 

The titanium we use is a durable, highly corrosion-resistant and lightweight metal that is extremely comfortable to wear.

Pearl

We use cultured pearls from oysters and freshwater mussels, which are carefully selected by us. Pearls are a natural product and are sensitive by nature, so they must be carefully protected.

Crystals

We use synthetic crystals, also known as recycled crystals, which are single crystals, also known as synthetic crystals.
Recycled crystal is the use of hydrothermal crystallization method "imitating the growth process of natural crystal", the natural silica ore and some chemicals in the autoclave, after 1-3 months of time gradually cultivated.
It is identical to natural crystal in terms of chemical composition, molecular structure, optical properties, mechanical and electrical properties, while birefringence and polarization, recycled crystals are purer than natural crystals, with better color and luster.
After processing (cutting, grinding, polishing) to get a variety of shapes of particles crystal bright, brilliant, and wear-resistant, corrosion-resistant.
