Diamond weight and value analysis: How to use critical points to choose cost-effective diamonds

The relationship between the value and weight of a diamond does not show a linear growth, but is affected by many factors, especially the existence of a "critical point". For example, a 1 carat diamond is worth much more than two 50-carat (0.50 carat) diamonds of the same grade combined. This nonlinear relationship provides us with some cost-effective strategies when choosing engagement rings or wedding rings . This article takes a closer look at how diamond weight relates to the cutoff point and how to find the ideal diamond within your budget.

What is the weight cutoff for diamonds?

The critical weight points of diamonds refer to certain specific weight units, such as 0.30 cal (30 parts), 0.50 cal (50 parts), 1 cal, etc. These weights will see a significant jump in price due to rarity and market demand. For example:

• A 0.98 carat diamond, although almost indistinguishable in size from a 1 carat diamond with the naked eye, is usually much cheaper.
• The same thing happens between a 49-part diamond and a 50-part diamond; even though they are almost the same size, the 50-part diamond is significantly more valuable.

Use critical point strategy to select cost-effective diamonds

Using these tipping points, we can choose a more affordable diamond without sacrificing appearance. For example:

• Choose a weight that is close to the critical point: for example, choosing a 90 weight (0.90 cal) or 98 weight (0.98 cal) diamond will ensure that the size of the diamond is close to 1 cal and save a lot of money.
• Consider the diameter of the diamond: In addition to its weight, the diameter of the diamond also affects its appearance. For example, a 0.98 carat round diamond and a 1 carat diamond have almost the same diameter, but the price may differ by 10%-20%.

Does the value of tipping point apply to cultured diamonds?

The value of the tipping point applies not only to natural diamonds , but also to cultured diamonds (also known as laboratory diamonds or artificial diamonds ). Since lab-grown diamonds are produced with more precise weight control, you’ll more easily find options that are closer to the cutoff point, such as 0.90 cals or 1.90 cals.

How to comprehensively consider other 4C standards?

Although weight is an important parameter of diamonds, you also need to consider other 4C standards (color, cut, and clarity) when choosing an engagement ring or wedding ring . Here are some suggestions:

• Color: Choose a G or H grade diamond for better value and still have a near colorless appearance.
• Cut: Diamonds with an Excellent or Ideal cut grade will have the best fire, even if they are slightly smaller in weight.
• Clarity: Diamonds with VS2 or SI1 grades usually have flaws that are difficult to detect with the naked eye, making them a good choice when your budget is limited.
