How are High Performance Diamonds different?

Diamond Education takes time and research. Most people don’t bother beyond the basics. Believe it or not, an investment of just 30 minutes in our education tutorials will prepare you with more “quality knowledge” than many workday jewelry salespeople have pursued. Read More…

What are ASET and Ideal-Scope images?

All diamonds look nice under bright lights, but most become noticeably average in normal conditions. Those which continue to sparkle and dance have good cut quality. At High Performance Diamonds we separate cut quality into two areas; Cut Performance, which revolves around light return, and Cut Precision which can take top performing diamonds to an even higher level. Read More…

What are Hearts & Arrows and Optical Symmetry?

Micro Cut Precision first became possible in the late 1980s in rounds and is only now surfacing in fancy shapes. This is a measure of how well all of a diamond’s facets align with each other in 3D. It takes improved tools, more time and higher skill sets to accomplish top precision. More importantly it expends more carat weight. When present in top-performing diamonds, cut precision can boost optical properties and overall performance in low-light conditions. Read More…

What is your policy on Conflict Diamonds?

All diamonds we source are guaranteed conflict-free, from known legitimate sources and in compliance with United Nations Resolutions, the Kimberley Process and United States Clean Diamonds and Patriot Acts. “Crafted By Infinity” diamonds are further protected under the Belgian Federal AML process and voluntary participation in the JVC-USA Patriot Act Compliance Program. Read More…
