Sponge Coral

Sponge coral refers to a type of coral that is commonly used in jewelry and decorative items. It is not a true coral species but rather a trade name for a variety of corals that have a porous, sponge-like appearance. These corals belong to the genus *Melithaea* and are typically found in the Indo-Pacific region.

The porous nature of sponge coral makes it suitable for carving and shaping into beads, cabochons, and other ornamental pieces. The natural color of sponge coral can range from white and cream to shades of pink, orange, and red. However, it is not uncommon for the coral to be dyed to enhance or change its color.

It's important to note that the use of coral in jewelry and other products has raised concerns about environmental sustainability and the impact on coral reefs. Harvesting coral, even if it's sponge coral, can contribute to the depletion of coral populations and damage to marine ecosystems. As a result, there has been a growing emphasis on promoting sustainable and ethical practices within the coral industry.

When purchasing products made from sponge coral or any other type of coral, it's advisable to ensure that the material has been sourced responsibly, ideally through sustainable practices or from sources that adhere to environmental conservation guidelines.
