Total Carat Weight

​

Per the Gemological Institute of America, “carat weight” refers to the weight of a single stone, “total carat weight” – sometimes abbreviated “tcw” – is used to describe the weight of all the diamonds in a multi-stone ring".

 

Below are the most common total carat weights for diamond rings:

​

1 to 1.24 CT Diamond Rings

​

The most popular total carat weight for a diamond ring is in this range.  These are mostly diamond solitaire rings, ie diamond rings featuring only one, single diamond.

​

1.25 to 1.49 CT Diamond Rings

​

Diamond rings in this carat range are mostly diamond solitaire rings as well.

​

1.50 to 1.74 CT Diamond Rings

​

Once you get into this total carat range multiple diamond stones become more commonplace although vast majority are still solitaires.

​

1.75 to 1.99 CT Diamond Rings

​

Single diamond stones in this carat weight become more rare and accent diamonds more common.

​

2 to 4.99 CT Diamond Rings

​​

This is a big range group as diamond rings containing multiple stones are predominant.  Single solitaire diamond rings in this carat range can command high prices if the diamond is of high quality.

​

5 to 9.99 CT Diamond Rings

​

Almost all of the diamond rings in this range are multiple stone rings.  It's difficult to find quality diamonds in this carat size as they are extremely rare.
