How to tell if Natural Lapis Clover Stone has been treated?

Hey there! I'm a supplier of Natural Lapis Clover Stone, and I often get asked how to tell if this beautiful stone has been treated. Well, I'm here to share some tips and insights based on my experience in the business.

First off, let's understand what Natural Lapis Clover Stone is. It's a unique and eye - catching gemstone that resembles a four - leaf clover in shape. You can check out more about it on this page: Natural Lapis Clover Stone.

Visual Inspection

The first thing you can do is a simple visual inspection. Natural lapis lazuli, the main component of the Natural Lapis Clover Stone, has a distinct appearance. It usually has a deep blue color with golden flecks of pyrite. These flecks are like little stars in the stone.

If the stone has a uniform blue color without any natural variations or flecks, it might be a sign of treatment. Some treatments can be used to make the color more consistent, but in nature, stones rarely have such a perfect, unchanging hue. Also, look for any signs of dye. If the color seems too intense or concentrated in certain areas, it could be dyed. For example, if you see a very dark blue line running through the stone that doesn't look natural, it's likely been treated with dye.

Another visual clue is the surface of the stone. Natural stones have a certain texture. They might have small pits or bumps that are a result of their formation process. If the surface is overly smooth and shiny, like it's been polished to an unnatural degree, it could be a sign of treatment. Sometimes, a clear coating is applied to the stone to enhance its shine, but this isn't a natural characteristic.

Hardness Test

Lapis lazuli has a hardness of around 5 to 5.5 on the Mohs scale. You can do a simple hardness test at home (but be careful not to damage the stone too much). Find a material with a known hardness. For example, a copper penny has a hardness of about 3.5. If you gently try to scratch the stone with the penny and it gets scratched easily, it might not be a pure, untreated lapis.

However, if you try to scratch it with a steel nail (hardness around 6.5) and the stone shows no sign of scratching, it's likely that something has been done to increase its hardness. This could be a form of treatment like impregnation with a hardening resin.

Chemical Tests

Now, chemical tests should be done with extreme caution. I don't recommend doing them at home unless you're a professional. But in a laboratory setting, some chemicals can be used to detect treatments. For example, a weak acid can be used to test for the presence of dyes. If the acid causes the color to bleed or change, it's a clear sign that the stone has been dyed.

Another chemical test can detect the presence of resins or other impregnating materials. A solvent can be used to dissolve the suspected coating or filling. If the stone's appearance changes after the solvent is applied, it indicates that there's some form of treatment.

UV Light Test

A UV light test can also be quite revealing. Natural lapis lazuli usually shows a dull or no reaction under UV light. If the stone glows brightly or has a fluorescent effect, it could be a sign of treatment. Some dyes or impregnating materials are fluorescent and will show up under UV light. You can buy a simple UV flashlight online and shine it on the stone in a dark room. If you see a strange glow, it's something to be wary of.

Comparison with Known Natural Stones

One of the best ways to tell if a Natural Lapis Clover Stone has been treated is to compare it with known natural stones. As a supplier, I have a collection of untreated stones that I use as references. You can look at the color, texture, and other characteristics of these natural stones and compare them with the one you're interested in.

If you're not a supplier like me, you can visit a reputable gemstone dealer or museum and look at their natural lapis lazuli specimens. This hands - on comparison can give you a better sense of what a natural stone looks like.

The Importance of Certification

When buying a Natural Lapis Clover Stone, it's always a good idea to ask for a certification. A gemological laboratory can test the stone and provide a report stating whether it's natural or treated. Reputable labs like the Gemological Institute of America (GIA) are well - known for their accurate and reliable testing.

If a seller can't provide a certification, it should raise a red flag. It might mean that they're trying to hide something about the stone's treatment status.

Other Similar Stones

There are other types of clover - shaped stones in the market. For example, the Natural Black Onyx Clover Stone and the Natural Green Agate Clover Stone. Each of these stones has its own characteristics and ways to detect treatments.

For the Natural Black Onyx Clover Stone, look for color uniformity. Natural onyx usually has some natural banding or variations in color. If it's a solid, jet - black color with no signs of natural markings, it could be dyed.

The Natural Green Agate Clover Stone should have a natural, earthy green color. If the color is too bright or neon - like, it might be a sign of dyeing. Also, check for any signs of filling or coating on the surface.

Why It Matters

Knowing whether a Natural Lapis Clover Stone has been treated is important for several reasons. First, natural, untreated stones are generally more valuable. They have a unique beauty that comes from nature, and collectors and enthusiasts often prefer them.

Second, if you're buying the stone for its metaphysical properties, natural stones are believed to have stronger energy. Many people think that treated stones have a diluted or altered energy field.

Finally, it's a matter of honesty and transparency in the market. As a supplier, I believe in providing my customers with accurate information about the stones I sell.
