White Sapphire vs. Moissanite | Love & Promise Blog

Diamond vs white sapphire are both colorless gemstones that can add a touch of brilliance to any piece of jewelry. However, they have distinct characteristics that can influence your decision. Here’s a breakdown to help you choose the perfect stone:

Shine and Sparkle

  • Diamonds: Renowned for their fiery brilliance, diamonds have a high refractive index, meaning they bend light more dramatically. This results in a play of colors, called “fire,” and a dazzling sparkle, known as “scintillation.”
  • White Sapphires: While beautiful, white sapphires exhibit a subtler sparkle with a silvery-white hue. They lack the intense fire of diamonds.


  • Diamonds: Diamonds are the hardest natural substance on Earth, ranking a perfect 10 on Mohs scale of mineral hardness. This makes them highly resistant to scratches and chipping, ideal for everyday wear.
  • White Sapphires: Sapphires are very hard, clocking in at 9 on Mohs scale. They can withstand most everyday wear and tear but are slightly more susceptible to scratches than diamonds.


  • Diamonds: Diamonds are significantly more expensive than white sapphires of comparable size. The price difference can be substantial, especially for larger stones.
  • White Sapphires: Due to their abundance, white sapphires are much more affordable than diamonds. This allows you to get a larger stone for your budget.

The Look

  • Diamonds: Diamonds offer a classic, icy brilliance that has been a symbol of luxury for centuries. Their fire and sparkle create a mesmerizing display.
  • White Sapphires: White sapphires have a cooler, softer light reflection. They can appear almost icy or snowy and pair well with platinum or white gold settings.

Making Your Choice

The ideal stone depends on your priorities. If brilliance and tradition are paramount, a diamond might be the perfect choice. However, if you desire a larger, more affordable stone with a subtle elegance, a white sapphire could be a stunning alternative.

Here are some additional factors to consider:

  • Lifestyle: If you have an active lifestyle, a diamond’s superior hardness might be a wise investment.
  • Setting: White sapphires can look especially captivating in vintage-inspired or halo settings.
  • Personal Preference: Ultimately, the most important factor is choosing a stone that you find beautiful and meaningful.

Whether you select a diamond or a white sapphire, you’re sure to end up with a gorgeous and timeless piece of jewelry.
