What is a Composite Diamond?


Looking for an affordable diamond ring that meets your budget? If you want the look of a large stone without the hefty price tag, take a look at composite diamonds. Rings and other composite diamond jewelry are intricately beautiful and have the gorgeous vintage look that is so popular today.

Keep reading to learn about composite diamonds, what to look for when shopping for a composite diamond, and if this is the right style of ring for you.

What are Composite Diamonds?

Composite diamonds are several diamonds carefully set together creating a large diamond cluster or diamond shape. The diamonds themselves can be fused, glued, or set very close together. They are often fused together with two or more diamonds of equal or different, forming a unique pattern.

Many composite diamond rings, necklaces, and other jewelry pieces contain multiple diamonds of varying sizes.

While traditional rings offer a single diamond center stone, composite diamonds have multiple stones and offer an elegant vintage look with intricate detail. This creates the look of a larger diamond without compromising the sparkle and brilliance of your diamond, often at a lower price than a traditional diamond ring.

Carat Weight vs Total Carat Weight

Carat weight refers to the unique unit of weight measurement or gemstone. This is the psychical weight of an individual diamond or gemstone, and one of the 4Cs – color, cut, clarity, carat weight. This is not to be confused with total carat weight, which is an entirely different measurement.

Total carat weight represents the total weight of all diamonds or other gemstones in a piece of jewelry when more than one stone is used. It is important to know the total carat weight in a composite diamond ring, which can then be compared against the individual carat weight of a single diamond to see how the prices compare. Sets of jewelry, or jewelry sold in pairs, are typically sold using TCW.

One carat is typically 200 mg, so a lower carat weight is a factor that goes into a diamond or gemstone’s price. Because composite rings are made up of smaller diamonds that are lower in carat weight, they tend to be priced lower than a standard diamond ring.

Pros of Composite Diamonds

  1. Affordability and Price – if you are on a budget and still want a gorgeous ring it’s hard to find a better value than a composite diamond
  2. Variety of Designs and Diamond Shapes a Single Stone Ring Doesn’t Offer. You can often find unique designs or shapes like a flower, oval, halo, chevron, or a cluster creating the vintage look many people love
  3. Multiple different stones, and gemstones can be incorporated into a composite ring, imitating the appearance of a larger stone
  4. Everyday wear to compliment an existing solitaire diamond ring or wedding band in a solitaire color.
  5. Composite diamond jewelry allows for more artistic expression in the design and a greater degree of versatility. A composite diamond ring can look like a traditional diamond solitaire from a distance or boast a more intentionally casual, trendy look

Cons of Composite Diamonds

  1. Higher Repair Costs since there are often multiple diamonds or gemstones in different sizing clustered together, these stones may come loose over time
  2. Future value can be limited due to not having one single diamond, and instead multiple diamonds in a variety of sizes
