How to Assess the Condition of Your Marbles
Marble is a beautiful, natural stone that can add a touch of elegance to kitchens, bathrooms, entryways, and serene outdoor spaces. Its versatility makes it a popular choice for homeowners, and while trends may come and go, incorporating them into your design with careful consideration can help you create a space that feels uniquely yours.
Marble comes in a variety of colors and shades, from white to black. Generally, darker marbles are more durable, and can better stand up to harsher weather conditions and wear and tear. However, some lighter colored marbles are also a good choice, as they can complement more delicate architectural details and create a softer, more elegant look.
The density and porosity of a marble affect its durability, as well as how it will react to different types of cleaners and stains. For example, a softer, more porous marble such as Calacatta may show etching and staining more prominently than a harder, denser stone such as Vermont Danby.
As a collector, the condition of your marbles can dramatically affect how much they are valued for. Even if you have found a marble in your collection that is valued a certain way in a price guide, the slightest difference in color or patterning can mean that someone is willing to pay significantly more for it than you are. This is why it is so important to know what to look for when judging marble condition.
To begin assessing the condition of your marbles, you will need to be familiar with the two basic marble grading systems: Collectible, and Minus (-) or Plus (+) ranges. While the minus (-) and plus (+) grading systems are somewhat subjective, both generally call upon the same criteria: Marbles in the Collectible range should be free of visible damage and able to be graded mint from one side or another. Marbles in the Near Mint range should have a few flakes, moons, scratches and abrasions, but be free of any major, deep, or obvious damage.
Most marble collectors will vehemently deny that they collect marbles solely for the potential financial gain, but many dealers also make a living by buying and selling marbles, so it is a necessary part of the business. Knowing what to look for when evaluating marbles, and understanding the nuances of the grading systems can help you avoid getting duped by an unscrupulous dealer and find the marbles that are right for your collection.
