Moissanite is an affordable diamond alternative that’s nearly as hard as diamond and has similar sparkle and brilliance. It was discovered in 1893 in a meteorite crater. Moissanite costs less than diamonds. Due to its higher refractive index, it sparkles more in the light. Furthermore, Moissanite has more sustainable and ethical production methods compared to mining from the earth like diamonds do, since it is manufactured instead.


  • Nearly as hard as diamonds with similar sparkle and brilliance
  • More affordable than diamonds
  • Sustainable and ethical choices than diamonds


  • Some people may prefer the authenticity and rarity of a diamond
  • Moissanite offers more of a rainbow sparkle than diamonds – which may not be everyone’s cup of tea


Lab-grown Diamonds: The Sustainable and Ethical Choice

Lab-grown diamonds, also referred to as cultured or synthetic diamonds, are real diamonds grown in a laboratory rather than mined from the earth. While they possess similar physical and chemical characteristics as natural diamonds, they’re more sustainable and ethical. Plus, lab-grown diamonds tend to be cheaper than their mined counterparts without involving mining-related ethical or environmental concerns.


  • Real diamonds with the same physical and chemical properties as natural diamonds
  • More sustainable and ethical than mined diamonds
  • Less expensive than natural diamonds


  • Some people may still prefer the authenticity and rarity of a natural diamond
  • Lab-grown diamonds may not hold their value as well as natural diamonds

Colored Gemstones: The Unique and Personalized Option

Not only are they more affordable than diamonds but they come in an array of colors too.

  • Unique and personalized option with a variety of colors to choose from
  • Often less expensive than diamonds
  • More sustainable than diamonds


  • May not be as durable as diamonds
  • May not have the same sparkle or brilliance as diamonds

White sapphire is an affordable and durable diamond substitute with a similar appearance. It is formed naturally from corundum, making it nearly as hard as diamonds. White sapphire makes for great jewelry pieces due to its hardness compared to diamonds.


  • Durable and affordable diamond alternative
  • Has a similar look to a diamond
  • Natural and sustainable


  • May not have the same sparkle or brilliance as diamonds
  • May not be as rare or valuable as a diamond


Are diamond alternatives as durable as diamonds?

Are diamond alternatives more sustainable than diamonds?

Yes, many diamond alternatives are more eco-friendly than their diamond counterparts. Lab-grown diamonds and moissanite are created in a lab rather than mined from the earth, thus reducing their environmental impact. Colored gemstones tend to be mined in smaller quantities and often come from conflict-free zones.

Are Diamond Alternatives Cheaper Than Diamonds?

Many diamond alternatives are more cost-effective than diamonds. Moissanite, white sapphire, and colored gemstones tend to be less costly than diamonds while lab-grown diamonds can be up to 30% less costly than natural diamonds.


Selecting the ideal engagement ring can seem like a daunting task, but there are many diamond alternatives that offer beauty, durability, and sustainability. Moissanite, lab-grown diamonds, colored gemstones, and white sapphire are just some of the options available; each has its own advantages and drawbacks so it’s important to consider your budget, style preferences, and values when making your selection. No matter which diamond alternative you opt for though – its most significant quality should always remain: the love and commitment it symbolizes.

Other Tips

1) Measure your finger in warm temperatures at the end of the day.

2) If your knuckle is a lot larger than the base of your finger, measure both the base of your finger and your knuckle and select a size between the two.

3) When considering a wide band, move up a size from your measurement, for comfort’s sake.
