This often tiny hallmark appears discreetly, sometimes applied to a link or less visible part of the jewellery item. Our main image shows the stamp on a link from a small gold charm. Our image has been magnified to provide an example of the hallmark. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is the head shown above the 800 mark?<\/h2>\n\n\n\n<p>Due to the hallmark&#8217;s size, the boundary box&#8217;s shape, or cartouche, many collectors struggle to find it, but from the illustration above, the mark clearly shows a snarling hound with his tongue out. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The appearance of a Stag and 800.<\/h2>\n\n\n\n<p>Some Portuguese Gold jewellery items feature a stag with antlers and the same 800 number. Interestingly, this edition of the hallmark dates from 1998. For this reason, items with the hound and 800 mark pre-date items with the stag symbol. <\/p>\n\n\n\n<p><em><a href=\"https:\/\/isle-of-wight-jewellery.co.uk\/collections\/pre-loved-jewellery\">View some of our pre-loved collections on our showroom website including a selection of antique gold jewellery items for sale. <\/a><\/em><\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-style-default\"><a href=\"https:\/\/isle-of-wight-jewellery.co.uk\/collections\/pre-loved-jewellery\/products\/56-inch-9ct-gold-victorian-etruscan-chain-with-picture-frame\"><img loading=\"lazy\" decoding=\"async\" width=\"850\" height=\"541\" src=\"https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2024\/09\/Etruscan-long-guard-chain-on-wood.jpg\" alt=\"One of our pre-loved antique items of jewellery - a 56 inch long-guard chain \" class=\"wp-image-22973\" srcset=\"https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2024\/09\/Etruscan-long-guard-chain-on-wood.jpg 850w, https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2024\/09\/Etruscan-long-guard-chain-on-wood-300x191.jpg 300w, https:\/\/www.serendipitydiamonds.com\/blog\/wp-content\/uploads\/2024\/09\/Etruscan-long-guard-chain-on-wood-768x489.jpg 768w\" sizes=\"auto, (max-width: 850px) 100vw, 850px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Why does 800 mean &#8211; 19.2 Carat Gold<\/h2>\n\n\n\n<p>As most of us know, 100% Gold is 24 carat.
