Solitaire trillions exhibit a convex cut, featuring a curved profile, while accent stones showcase an uncurved or concave cut.<\/p>\n\n\n\n<p>In the dynamic world of diamond cutting, the Trillion diamond cut emerged as a game-changer, challenging traditional attitudes toward patenting gem cuts. In the 1970s, two standout cuts, Leon Finker&#8217;s Trillion and Henry Grossbard&#8217;s Radiant, played pivotal roles. <\/p>\n\n\n\n<p>Finker introduced the triangular brilliant design but initially refrained from patenting or registering the name. In contrast, Grossbard patented and trademarked his innovative mixed cut, gaining complete control over it. Finker&#8217;s delay in protecting the Trillion allowed its widespread adoption, with consumers and jewellers commonly referring to any triangular diamond as a &#8220;trillion.&#8221; <\/p>\n\n\n\n<p>Despite eventually obtaining a patent, Finker couldn&#8217;t secure the trademark due to its similarity to &#8220;trilliant.&#8221; Grossbard&#8217;s success highlighted the importance of safeguarding cut designs, leading to a surge in cut patents post-1975. The Trillion&#8217;s journey reflects the shifting landscape of gem cut protection, with Grossbard&#8217;s Radiant setting a precedent for securing rights to valuable cuts in the industry.<\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">Alternative names for triangular-shaped diamonds include&nbsp;<\/span><strong><span data-preserver-spaces=\"true\">Trillion-shaped diamonds.&nbsp;<\/span><\/strong><span data-preserver-spaces=\"true\">Also,<\/span><strong><span data-preserver-spaces=\"true\">&nbsp;Trilliant shaped diamonds.<\/span><\/strong><\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-vimeo wp-block-embed-vimeo wp-embed-aspect-1-1 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Trilliant Cut Diamond\" src=\"https:\/\/player.vimeo.com\/video\/732115779?dnt=1&amp;app_id=122963\" width=\"730\" height=\"730\" frameborder=\"0\" allow=\"autoplay; fullscreen; picture-in-picture\"><\/iframe>\n<\/div><\/figure>\n\n\n\n<p><span data-preserver-spaces=\"true\">Common misspellings include<\/span><strong><span data-preserver-spaces=\"true\">&nbsp;\u2018Trillion cut\u2019,&nbsp;<\/span><\/strong><span data-preserver-spaces=\"true\">and diamond reports usually refer to a Triangular modified-brilliant cut.<\/span><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"850\" height=\"636\" src=\"https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2017\/12\/Diamond-macle-and-trigons.jpg\" alt=\"Diamond macle with trigon crystals\" class=\"wp-image-18083\" srcset=\"https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2017\/12\/Diamond-macle-and-trigons.jpg 850w, https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2017\/12\/Diamond-macle-and-trigons-300x224.jpg 300w, https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2017\/12\/Diamond-macle-and-trigons-768x575.jpg 768w\" sizes=\"auto, (max-width: 850px) 100vw, 850px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-a-macle\"><span data-preserver-spaces=\"true\">What is a Macle?<\/span><\/h2>\n\n\n\n<p><span data-preserver-spaces=\"true\">Macle describes the triangular shape of a rough diamond with a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Macle\">twin crystal form<\/a>.

As a result, Trilliant cut diamonds often disguise small internal characteristics within the diamond.<\/span><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">The antique alternative to this diamond shape was the step-cut triangular baguette.<\/span><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">Antique step-cut variations date back to the 1920s. However, antique triangular shapes no longer appear commercially.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-many-facets-does-a-trillion-diamond-have\"><span data-preserver-spaces=\"true\">How many facets does a Trillion diamond have?<\/span><\/h2>\n\n\n\n<p><span data-preserver-spaces=\"true\">But what about the number of facets? Trilliant-cut diamonds typically have around 44 facets. However, some trillion-cut diamonds feature 50 facets, which add brilliance and fire to the diamond.<\/span><\/p>\n\n\n\n<p><span data-preserver-spaces=\"true\">The sides of a Trilliant vary with a straight or curved shape, which affects the aesthetics of the diamond.

For this reason, we assess each diamond on its appearance, carat weight, and physical size. Visually striking examples often have smaller carat weights<\/span> than thicker diamonds. For this reason, never purchase a loose diamond without <span data-preserver-spaces=\"true\">seeing a photograph of the stone.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-trilliant-cut-diamonds-for-three-stone-engagement-rings\"><strong><span data-preserver-spaces=\"true\">Trilliant cut diamonds for three-stone engagement rings<\/span><\/strong><span data-preserver-spaces=\"true\">.<\/span><\/h2>\n\n\n\n<p><span data-preserver-spaces=\"true\">Trilliant-cut<\/span> diamonds are sometimes used as side stones in a diamond ring\u2014often cut into matching pairs.
