Introduction of Red Coral Gemstone

Red Coral is one of the semi-precious gems that have very attractive red or orange-reddish color. Such gem is an organic one formed from the skeleton of coral polyps from deep beneath the ocean. The richness attached to the gem for ages is that of metaphysical property, hence it is a symbol of vitality, force, or power. Red Coral gemstones are used in astrology to invoke the effects of Mars where it boosts confidence, health, or success.

 

Origin and Composition of Red Coral

Red Coral originates through natural processes as the skeletons of marine organisms called coral polyps. These secreted skeletons of coral polyps build hard skeletons of calcium carbonate that later contribute to the Red Coral gemstone. Good quality Red Coral is found in the Mediterranean Sea, the Pacific Ocean, and areas surrounding Japan and Taiwan.

 

Meaning of the Red Coral Gemstone

Not only is Red Coral a beauty gemstone but also one of great spiritual and astrological significance. It is a stone within Vedic astrology, representing Mars. This planetary position bestows strength, courage, and passion. According to its said benefits, people even wear Red Coral for the enhancement of one’s vitality, for the boosting of immunity, and for protection against evil impulses. The bright red color is a symbol of energy, determination, and the power to overcome obstacles.

 

Identification of Real Red Coral Gemstone

  1. Surface Inspection

One of the first tests in determining whether a Red Coral gemstone is genuine or not should be an examination of its surface. Authentic Red Coral is typically smooth and polished but with natural grain patterns. It is good to check for small marks that are readily visible showing the natural feature of the gemstone; synthetic or fake corals may tend to appear too even or shiny.

  1. Density Test

Red Coral has a unique density that can be used to identify it from its copies. A genuine Red Coral sinks in water since it is relatively highly dense. Facsimiles, particularly those that have a glass or plastic base, will float or weigh less light.

  1. Acid Test

A tested method to authenticate natural Red Coral is the acid test. A few drops of nitric acid on the top of the gem may check out whether it’s genuine or not. Natural corals react to the acid by showing slight effervescence, whereas artificial plastics or glass don’t.

Warning: Acid testing the stone will destroy it if not done properly. Instead, consult a professional gemologist for proper testing.

  1. Heat Test

Red Coral can be identified by applying gentle heat. The real Red Coral does not change color under mild heat, but the fakes melt or turns dark.

  1. Test of Magnification

Under a jeweler’s loupe or microscope, closely study the gem. Natural Red Coral has natural surface textures or striations. The artificial stones often show the surface texture free and polished, which means it was made artificially.

  1. Rubbing Test

A simple rubbing test will determine if it is actual Red Coral. Rub the stone lightly on a cloth; a real Red Coral will leave a red powdery streak since it is an organic origin, while the fake leaves no marks.

 

Physical Properties of Red Coral Gemstone

  1. Color

The most distinctive characteristic of Red Coral is that it occurs in colors ranging from deep red to vibrant orange-red. It is mainly reliant on the origin site of the coral; since Mediterranean Red Coral is considered to be the most valuable because of its deep, blood-red coloration.

  1. Hardness

Red Coral is relatively soft, with a rating of 3.5 to 4 on the Mohs hardness scale. This means it should be handled with the utmost care and kept away from scratches. Its softness is an indication of its authenticity because harder imitations are usually synthetic or glass.

  1. Chemical Composition

The chemical composition of Red Coral is essentially calcium carbonate (CaCO), which explains its organic specificity. This can easily be tested to ensure a stone is not an imitation coral, as imitations are usually made from material like glass or plastic.

  1. Transparency

Red Coral is opaque; thus, light cannot pass through it. That is one characteristic feature because some synthetic corals are found to be semi-transparent to light.

  1. Luster

The luster of the Red Coral is generally vitreous to waxy. A natural, soft glaze develops to the genuine Red Coral when polished, so that is one feature to differentiate it from too shiny synthetic substitutes.

  1. Specific Gravity

Specific Gravity of Red Coral falls between 2.6 to 2.7. This property can be helpful in distinguishing between the original stone and fake, as fake stones mostly have varied densities.

 

 

Different Types of Red Coral Gemstones

There are several types of the Red Coral Gemstone, categorized on the basis of color and texture:

  1. Italian Red Coral

Italian Red Coral is very famous for its origin from the Mediterranean Sea and is recognized by its deep red coloration as well as high quality. It’s totally regarded as the most precious and natural variety of Red Coral.

  1. Japanese Red Coral

Japanese Red Coral, recovered from the coast of Japan, is characterized with bright red coloration and is sometimes translucent. 

  1. Pacific Red Coral

It appears to be light red in color and is derived from areas within the Pacific. As this is one of the less expensive types of Red Coral, it does not possess astrological and metaphysical significance.

 

Common Red Coral Gemstone Treatment

Although some forms of Red Coral gemstones are tinted, they also may be treated with dyes as follows to enhance their color and appearance:

  1. Dyeing

Dyeing is a common treatment provided merely for the intention of coloring inferior quality Red Coral. When red dye is applied on the stone, that fades away. But in the natural, untreated Red Coral, color does not fade.

  1. Polish

Red Coral stones are polished to improve luster and surface finish. Though inner properties may not be altered, outer appearance of the stone changes.

  1. Waxing

The minor surface imperfections of Red Coral are filled by waxing. Common, it should be revealed since it affects the value of the gemstone.

 

How to Take Care of Your Red Coral Gemstone

Proper care will help preserve the beauty and quality of your Red Coral gemstone.

Store with Care: Keep Red Coral away from harder gemstones; it scratches easily.

General Cleaning: Clean carefully with a soft, moist cloth. Do not use ultrasonic cleaners to clean the stone since they can damage it.
