They&#8217;re known to be practically defect-free and are single-crystal structures more likely to resemble naturally occurring, non-synthetic diamonds, which is one of the reasons they are so popular.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mono-crystalline&#8217;s single-crystal structure makes them larger with much more predictable, defined fracturing planes and they are noticeably longer-lasting. Having naturally occurring cleavage planes in their crystal structure allows them to chip in a controlled way along these fracturing planes, breaking up during the course of normal use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This micro-chipping renews the abrasive function of the diamond&#8217;s sharp, defined cutting edges, refreshing them so they act like new diamonds and quickly remove steel while still maintaining consistency in size to their specified micron rating.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Due to this process they are known to have excellent cutting performance, giving your blade&#8217;s edge the ability to get, and hold, its crisp bite for a long time. They are especially good at producing a more toothy, clean, linear micro-scratch pattern on your bevel, creating a competently refined, thinned-out apex with a magnificent mirror polish and bite.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mono-crystalline diamonds aren&#8217;t just found in high-quality stropping emulsions. They are also commonly used as the sole abrasive on most diamond sharpening stones produced by many of today&#8217;s top-tier manufacturers due to their cutting longevity and overall performance.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Poly-crystalline Characteristics<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Poly-crystalline synthetic diamonds are manufactured solely in laboratories, meaning they are more expensive to produce than Mono-crystalline diamonds. Because of this they are comparatively less common.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These diamonds are characterised by clusters of countless incredibly small diamonds bonded together to form complex, random, unpredictable shapes and cutting edges\u2014similar to miniature fragments of shattered safety glass.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They&#8217;re known to cut fairly aggressively at first due to their inherent extreme hardness. Their multi-faceted structure means they have multiple cutting edges that are multi-directional, allowing a single diamond particle to bite into the bevel multiple times during a single pass. The downside is a less refined stropped edge that may produce somewhat unpredictable results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In theory, these harder bonded diamond facets are more friable, breaking apart over time into new, smaller cutting particles. These renewed edges produce irregularly shaped, finer diamonds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, however, they are extremely tough\u2014too hard-wearing to fracture significantly under the pressure applied by normal stropping methods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Due to their hard, small, wear-resistant particles they provide a softer progression and leave a pronounced, smoothed-out bevel. After only mild use, their small size means material is lost fairly quickly as the fine fragments become dislodged from the strop&#8217;s surface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It must be noted that they also produce an extraordinary polished edge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These diamonds can also be found in applications such as stone masonry, jewellery manufacturing and associated tooling, where high hardness and wear resistance are preferred.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Summary of Their Main Differences<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Mono-crystalline Summary<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Each particle is a single, solid crystal with defined cleavage planes and naturally sharp edges.<\/li>\n\n\n\n<li>As they wear during stropping, they fracture along their natural planes, constantly exposing fresh cutting edges.<\/li>\n\n\n\n<li>The edges cut cleanly into hard steels, producing concentrated, linear scratch patterns.<\/li>\n\n\n\n<li>Excellent for long-lasting, fast and consistent material removal.<\/li>\n\n\n\n<li>Produces refined mirror-polished edges that retain a crisp bite over time.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Poly-crystalline Summary<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Clusters of countless microscopic synthetic diamond particles bonded together with multi-directional cutting edges.<\/li>\n\n\n\n<li>They lack larger fracturable cleavage planes but, under very high pressure, can break down into even finer particles.<\/li>\n\n\n\n<li>Theoretically creates new micro-edged fragments that smooth and polish steel rather than aggressively refining it.<\/li>\n\n\n\n<li>Ideal for lighter touch-ups and extremely high mirror finishes.<\/li>\n\n\n\n<li>Produces polished cutting bevels with a smoother overall surface.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Final Thoughts<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is no doubt these two synthetic diamonds represent the pinnacle of micron abrasives used for stropping. Both are capable of producing exceptionally refined edges with highly polished apexes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ultimately, the choice comes down to your budget and personal preference. Mono-crystalline diamonds provide fast, clean-cutting particles that create a refined progression, linear scratch pattern, crisp bite and remarkable mirror finish.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Poly-crystalline diamonds offer smaller, harder, wear-resistant particles that are gentler on your edge, producing a softer progression, a multi-directional scratch pattern and exceptionally polished, smoothed-out bevels.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mono-crystalline vs Poly-crystalline Synthetic Diamonds Here are some answers to common queries about the differences between&nbsp;Mono-crystalline&nbsp;and&nbsp;Poly-crystalline&nbsp;synthetic diamonds and emulsions containing these two different abrasives, specifically surrounding the context of stropping.
