Elongated Pear Shape Synthetic Opal

Synthetic opal is a man-made gemstone designed to replicate the chemical composition, internal structure, and physical properties of natural opal. It typically consists of silica spheres arranged in a highly regular, ordered pattern, which creates its characteristic play-of-color through light diffraction. Unlike natural opal, synthetic opals often display a more uniform and regular color pattern, sometimes described as a "chicken wire" or "lizard skin" appearance under magnification. They may contain resin (about 20%) combined with silica (about 80%) in some types, while others are resin-free and chemically identical to natural opal. Synthetic opals are generally more affordable, more durable, and less prone to cracking than natural opals. They do not fluoresce under UV light and can be distinguished by their uniformity and specific growth patterns. These qualities make synthetic opals popular for jewelry, offering vibrant colors and consistent quality at a lower price point.

What are the different types of opal？

Opal is classified into various types based on its body color, transparency, and play-of-color presence. The main types include:

Precious Opal: Known for its vivid play of color, precious opal includes varieties like black, white, and crystal opal. Black opal has a dark body tone that enhances its vibrant colors, making it the rarest and most valuable. White opal has a light, milky background, while crystal opal is transparent or semi-transparent with bright color flashes.

Common Opal: This opal lacks the play of color and features a more uniform body color, often in shades of white, gray, or other pastel hues.

Other notable types include:

Boulder Opal: Contains opal embedded in ironstone or sandstone, often with striking color patterns.

Fire Opal: Exhibits warm hues like red, orange, or yellow and can be transparent or translucent.

Water or Jelly Opal: Transparent or semi-transparent with a gelatinous appearance.

Pink, Purple (Morado), Blue, Green, and Colorless Opals: Each has unique color characteristics and is often used for decorative purposes.

Additionally, opals can be natural or synthetic, designed to mimic natural varieties. The diversity in types allows for a wide range of aesthetic options in jewelry and collections. View More
