Natural gemstones are minerals, rocks, and organic materials that form naturally in the Earth without human intervention through geological processes involving crystallization, heat, or pressure. These are valued for their unique characteristics, beauty, and rarity.

At JEWELNJOY, we offer an exceptional jewellery collection, with detailed gemstone descriptions and key attributes.

Gemstone Enhancements

Heating Enhancement is a widely used process in the gemstone industry that enhances the natural beauty of gemstones to improve its appearance, durability, or value or overall appearance. This method involves exposing gemstones to industry standard temperatures to bring out desirable qualities that might be less visible in their natural state. 

1. Heat Treatment: This is the most common and widely accepted enhancement, especially for sapphires, rubies, and tanzanite etc. Heat improves color and clarity by altering the gemstone's internal structure. The process is permanent and generally does not diminish value unless untreated stones are highly prized.

2. Oiling: Oiling is a common treatment primarily used for emeralds, rubies, and many other gemstones to maintain their shine and improve clarity. This common practice involves applying oils to enhance its visual appeal. If oiling involves filling fissures with materials like glass or resin for enhanced clarity, it will be disclosed in the product details.

3. Dyeing: Porous gemstones, such as agate or jade, may be dyed to intensify color. This treatment is less durable and often reduces the stone's value.

4. Filling: This process involves filling cracks in gemstones with glass or resin to improve appearance. It can significantly impact the gem's value and durability.

5. Irradiation: Topaz and colored diamonds are irradiated and then heated to achieve vibrant colors. This treatment is permanent and is the only practical way to achieve such vivid colors in these gemstones.

6. Diffusion: Diffusion enhances the surface color of a gemstone by introducing chemical elements under high heat. The gemstone is exposed to chemicals like titanium or beryllium that penetrate the surface layers.
