Why do 1.5 carat diamonds offer better value than 2 carat stones? 

One-and-half carat diamonds typically offer superior value compared to larger stones due to exponential pricing in the diamond market. While providing substantial visual impact, these natural gems cost significantly less per carat than 2 ct options. This “sweet spot” in the size-to-price ratio allows purchasers to acquire impressive, high-quality precious stones with excellent brilliance and presence while avoiding the premium pricing that begins at the two-carat threshold.

What clarity grade is most recommended when buying 1.5 ct diamonds? 

For 1.5 carat diamonds, VS1-VS2 clarity grades offer the optimal balance between quality and value. At this size, inclusions become slightly more visible than in smaller stones, making these clarity grades ideal for ensuring eye-clean appearance while avoiding the premium cost of VVS and flawless grades. When purchasing natural gems of this size, prioritizing excellent cut alongside appropriate clarity delivers the most impressive aesthetic value.

How do proportions affect the brilliance of one-and-half carat diamonds?

Proportions critically impact the brilliance and perceived size of 1.5 carat diamonds. Properly cut stones with ideal depth percentages and table ratios maximize light return, creating exceptional fire and scintillation. When evaluating these genuine precious stones, look beyond certificate grades to actual proportion measurements, as even GIA certified diamonds vary in their light performance based on these crucial parameters that directly affect both aesthetic appeal and real value.

What makes 1.5 ct diamonds increasingly attractive to collectors? 

One-and-half carat diamonds have gained popularity among collectors for their perfect balance of impressive size and acquisition value. These conflict-free gems offer substantial presence while remaining more accessible than larger stones. Collectors particularly seek rare combinations like D-color with VS clarity or unusual fancy shapes in this weight class, recognizing that these natural stones represent an excellent intersection of wearability, investment potential, and visual impact worth preserving.

Frequently Asked questions

What is a loose diamond?

A loose diamond is simply a diamond that hasn’t been set into a piece of jewelry yet. It’s a raw, uncut stone, ready to be transformed into something beautiful. 

Loose diamonds are the foundation of many stunning pieces, from diamond engagement rings to elegant bracelets, necklaces or eternity bands. They’re also used to create custom jewelry, allowing you to express your unique style. 

Shop loose diamonds and you’ll have the opportunity to choose your diamond from a wide variety of shapes, sizes, and qualities. Whether you’re looking for a brilliant round diamond, a classic emerald cut, or a sleek princess cut, loose diamonds offer incredible customization possibilities. 

No matter what kind of diamond you’re searching for, a loose diamond is the perfect starting point to create a timeless treasure that you’ll cherish forever.

What are conflict-free diamonds?

Conflict-free diamonds are diamonds that have been ethically sourced, meaning they were not mined in areas where the proceeds funded armed conflict or human rights abuses.  

While natural diamonds are often associated with these ethical concerns, conflict-free diamonds offer a solution. These diamonds with a clear, traceable origin are a responsible choice for you if you  want your diamond to reflect its values.

There are two main types of conflict-free diamonds:

  1. Natural Conflict-Free Diamonds

 These are natural diamonds that have been mined in areas where ethical practices and responsible sourcing are strictly enforced.  You can find the perfect conflict-free natural diamond by looking for certifications from reputable laboratories, e.g. GIA . 

  1. Grown Diamonds

 These are grown diamonds created in a lab, offering a completely conflict-free alternative. They’re chemically, physically, and optically identical to natural diamonds, but more affordable and environmentally friendly. However, at Reuven Veksler we never deal with grown diamonds. 

Whether you choose a natural or grown conflict-free diamond,  it’s vital to understand the certifications and guarantees that come with it.  

A conflict-free diamond will sparkle beautifully and reflect your commitment to ethical sourcing.  It’s a diamond that has been responsibly sourced and will embellish your diamond engagement ring or other pieces of jewelry that will complement women’s wedding outfits. 

The best diamonds to purchase

To find the perfect diamond you have to consider many factors, like symmetry, fluorescence, 4Cs, color grade. All that stuff canmake your head buzz, so we always recommend starting with your budget. Calculate how much you are willing to spend and what your limit is, after which you will definitely not be able to spend more.

The best diamond is the one that fits your expectations and budget. Of course, we recommend considering only natural stones, as they are time-tested symbols of nature’s majesty and beauty 

How to choose the right diamond for jewelry?

Selecting the ideal diamond for your jewelry can be a daunting task, but it’s also an exciting adventure! With so many options in the world of diamonds, it’s important to understand the key factors that will influence your choice. 

Let’s imagine you are eager to purchase a ring. First of all, determine your ring style. 

Think about the style of jewelry you want.  Is it a classic engagement ring, a delicate ring, or a statement piece? The setting and design of your ring will influence the diamond’s shape, size, and overall look. Secondly, never forget about 4Cs. Keep in mind that a good cut will ensure that light reflects beautifully from the diamond. In addition, diamonds with a higher color grade (closer to D) appear whiter when exposed to light. You can find beautiful diamonds with subtle hints of yellow, especially if you’re on a budget. Moreover, natural diamonds will have some inclusions, but they’re often invisible to the naked eye. Take into account that some diamonds with fluorescence can appear hazy or milky when exposed to ultraviolet light.  

With a clear understanding of the 4Cs and your personal preferences, you’re ready to find your dream diamond!  Remember that some diamonds may have more noticeable inclusions or a slightly warmer color, but still be beautifully brilliant. 

Where to buy certified loose diamonds?

When you’re ready to purchase a certified loose diamond, it’s essential to choose a reputable source to ensure quality, authenticity, and ethical sourcing. 

Ensure the diamond comes with a reputable certification from a respected laboratory like GIA, AGS, IGI. At Reuven Veksler, we always provide all necessary certificates and are ready to answer all your questions regarding the origin of your diamond. We do our best to make your diamond buying experience special and unforgettable
