    Frequently Asked Questions

    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.

    Understanding Diamond Quality and Certification

Professional gemological evaluation from laboratories like GIA or IGI provides authentication of natural origin, ensuring buyers receive conflict-free diamonds with documented quality characteristics rather than synthetic alternatives.

    Frequently Asked questions

    Why should I buy loose diamonds instead of pre-mounted stones? 

    Buying loose diamonds allows you to examine the stone’s natural characteristics without interference from settings, ensuring you purchase genuine, high-quality specimens. You can verify the diamond’s clarity, color grade, and cut quality independently, often achieving better value and cost efficiency. Loose stones also provide flexibility for custom jewelry creation, where you control both the diamond selection and setting design process.

    What certifications should I look for when purchasing diamonds? 

    GIA certified diamonds represent the gold standard in gemological evaluation, providing detailed analysis of cut, clarity, color, and carat weight. Other reputable certifications include IGI and HRD, particularly for stones originating from Antwerp’s diamond exchanges. These certificates document the diamond’s natural origin, conflict-free status, and authentic characteristics, protecting your investment and ensuring genuine quality.

    What are conflict-free diamonds and why choose them? 

    Conflict-free diamonds are ethically sourced stones that were not mined in areas where proceeds funded armed conflict or human rights abuses. These natural diamonds with clear, traceable origins represent a responsible choice for buyers who want their purchase to reflect their values. At Reuven Veksler, we deal exclusively with conflict-free diamonds that come with proper certifications from reputable laboratories like GIA, ensuring both genuine quality and peace of mind for your investment.

    Where should I buy certified loose diamonds for the best value? 

    When purchasing certified loose diamonds, choose reputable dealers who provide comprehensive documentation and ethical sourcing guarantees. Ensure each stone comes with certification from respected laboratories like GIA, AGS, or IGI to verify authenticity and quality. At Reuven Veksler, we offer conflict-free diamonds with lifetime warranties, complete provenance documentation, and expert guidance to make your diamond buying experience both secure and valuable, whether you’re seeking investment-grade stones or creating bespoke jewelry.
