Frequently Asked Questions

How Much Is a Diamond Worth?

The value of diamonds varies significantly based on factors such as the size of the stone, its quality and how it's cut. Sometimes, diamonds with provenance may be worth more than stones that don't come with a story. For example, if a famous actor once wore the diamond or it belonged to a historic queen, then it’s likely to be more valuable. The cost of diamonds can range from a couple hundred dollars to millions.

How Do You Buy a Diamond?

You can buy a diamond online at Allurez. You can buy certified loose diamonds to incorporate into later pieces or buy diamonds as part of your jewelry purchase.

How Do You Clean Diamonds?

Soak diamonds in a mild solution of water and liquid detergent. You can add a bit of ammonia to remove any film that might build up on the stone. If you're cleaning a diamond in a setting, gently remove dirt with a soft toothbrush. Dry the stone or jewelry with a soft cloth or use a blow dryer set on cool. Discover more tips on caring for your jewelry.

What Are the Four Cs of Diamonds?

The four Cs of diamonds are:

  • Carat. This is the weight of the diamond. It's a reflection of how big the stone is.
  • Clarity. This is a rating that grades the diamond on how free of imperfections it is.
  • Color. This is a rating that grades how free of color a diamond is.
  • Cut. This is how the diamond is cut. Examples are pear, solitaire and heart-shaped.

How Do You Pick a Diamond?

Picking the right diamond comes down to a combination of practical and personal preferences:
  • Consider your budget. How much can you afford to spend on the diamond and the jewelry? Start by looking at options within your budget.
  • What are your preferences? Do you care more about having a large stone or would you prefer a smaller one with a higher color and clarity rating?
  • What is the purpose of the diamond? What looks best may differ depending on the type of jewelry you want and the settings and companion stones you choose.

Where Can You Buy Diamonds?

You can typically buy diamonds at most jewelers. At Allurez, you can choose to purchase loose diamonds or shop a wide selection of diamond jewelry.

How Do You Judge Diamond Quality?

A diamond's quality is judged using the 4 Cs. The higher a diamond scores on cut, clarity, color and carat, the higher its perceived quality.

Who Buys Diamond Jewelry?

Men and women of all ages and backgrounds buy diamond jewelry. Someone who is proposing may buy a diamond engagement ring. Couples may buy diamond jewelry for specific anniversaries, and people may even buy diamond earrings, bracelets, necklaces or rings for themselves.

What Is a Lab-Created Diamond vs. a Natural Diamond?

The only difference between a lab-created diamond and a natural diamond is where it was made. Lab-created diamonds are made in labs while natural diamonds grow over billions of years in the earth. Otherwise, they are chemically the same.
