How Moissanite Differs from Diamond

• Composition. Moissanite is silicon carbide; diamonds are carbon.
• Hardness. Diamonds rank 10 on the Mohs scale, while moissanite is 9.25.
• Brilliance & Fire. Moissanite has a higher refractive index, displaying more rainbow-colored flashes.
• Color. Moissanite may have a slight yellow or green tint, unlike diamonds.
• Cost. Moissanite is less expensive than comparable diamonds.

Why Choose Moissanite Over Diamond?

• Value. Moissanite offers stunning sparkle at a lower price.
• Unique Appearance. Its higher refractive index results in a dazzling, colorful brilliance.
• Eco-Friendliness. Lab-created moissanite has a smaller carbon footprint and is conflict-free.

Types of Diamond Testers

• Diamond Tester Pen
  Function: Uses electrical conductivity.
  Usage: Common in pawnshops and jewelry stores.
  Note: Avoid touching metal to prevent incorrect readings. Press the tip flat against the stone with light pressure for accurate results.
  
  
• Thermal Conductivity Testers
  Function: Measures how quickly a material conducts heat. Accuracy: Effective but may misidentify some diamond simulants.
  
  
• Electrical Conductivity Testers
  Function: Assesses electrical conductivity.
  Accuracy: Diamonds are poor conductors compared to many simulants.
  
  
• Ultraviolet Testers
  Function: Uses UV light to detect diamonds.
  Accuracy: Less reliable as some simulants also fluoresce under UV light.

• Multi-Testers
  Function: Combines thermal and electrical conductivity tests. Accuracy: More reliable by cross-referencing results from different properties.
  
  

Distinguishing Between Diamonds and Moissanite

• Visual Inspection: Moissanite's higher brilliance and fire are noticeable with a jeweler's loupe.

• Inclusions Analysis: Diamonds have distinctive growth characteristics visible under magnification.
  
  
• Electrical Conductivity Test: Moissanite conducts electricity, unlike diamonds.
  
  
• Ultraviolet Light Test: Moissanite and diamonds fluoresce differently under UV light.
  
  
• Refractive Index Test: Measures how much light bends when entering the stone; moissanite has a higher refractive index.
  
  
• Double Refraction Test: Observing through a loupe, moissanite shows a double image of the facets due to its crystal structure.
