7 + 1 Tips on How to Choose the Carat of Diamond for Your Engagement Ring

Choosing an engagement ring is a special and significant moment in every couple’s life. Among the many decisions to be made, one of the most important is the choice of diamond carat weight. Carat not only determines the size of the diamond, but also affects the overall appearance and value of the ring. In this blog, we’ll walk you through the main factors to consider when choosing the ideal diamond carat weight, helping you make a choice that satisfies both your desires and those of your partner.

1. Understanding Carat

Carat (Ct) is the unit of measurement that indicates the weight of a diamond, with one carat equal to 0.2 grams. Although it is an indicator of size (diameter), carat weight is only part of the equation. The cut, shape and proportion of the diamond influence the visual perception of its size.

2. Balance the Budget

The budget is a crucial element in choosing the caliber. Higher carat diamonds tend to be significantly more expensive. It is essential to establish a realistic budget that includes both the diamond and the ring design. Bon Gioielli offers an excellent quality/price ratio, guaranteeing high quality GIA and IGI certified diamonds, both natural and laboratory, allowing you to find the perfect ring without compromises.

3. Consider Your Partner’s Preferences

Understanding your partner’s tastes and preferences is crucial. Some people prefer a larger diamond for a more impactful visual effect, while others may appreciate a smaller but higher quality stone. Look carefully at the type of jewelry your partner usually wears to get an idea of his or her preferences.

4. Evaluate the Ring Design

The design of the ring plays an important role in choosing the carat weight of the diamond. For example, a classic solitaire highlights the central stone, while a ring with diamonds set around it can enhance a lower carat central stone. Bon Gioielli’s collection includes classic solitaires, diamond-set solitaires and options with diamonds along the shank, allowing you to find the ideal combination.

5. Use the AR Virtual Try-ON

Bon Gioielli offers an innovative virtual “Try On” service available on the mobile version of our website, which allows you to see how the diamond looks on your finger. This tool is extremely useful for viewing different diamond sizes and finding the one that best suits your partner’s preferences.

6. Consider Proportion in Hand

The size and shape of the recipient’s hand are factors to carefully consider. A large diamond may look disproportionate on a petite hand, while a smaller stone may not have the same visual impact on a larger hand. Take these proportions into consideration to ensure the ring is perfect.

7. Enhance Quality

The quality of the diamond is just as important as its carat weight. The famous 4Cs (Carat, Cut, Color, Clarity) determine the beauty and value of a diamond. A high-quality diamond with excellent cut, superior color and clarity, can shine brighter even if it is lower in carat weight. At Bon Gioielli, each diamond is selected and certified to guarantee the highest quality.

8. Professional Consulting

Expert advice can make the difference in choosing the ideal diamond. Francesco Bon, founder of Bon Gioielli and internationally renowned gemologist, offers specialized consultancy and personally supervises every phase of the creation of the rings. His experience will guide you in choosing the perfect diamond, ensuring that every detail is taken care of with the utmost attention.
