Often mistaken for a precious metal in its own right, white gold is actually an alloy carefully formulated to offer luminous aesthetics and strength ideal for high-end pieces. This post will help you gain an in-depth understanding of what exactly white gold is, how it is composed, and why it is so highly valued in contemporary jewellery.<\/p>\n<h3 data-section-id=\"1h6mte3\" data-start=\"758\" data-end=\"784\">What is white gold?<\/h3>\n<p data-start=\"786\" data-end=\"1272\">White gold is a <strong data-start=\"807\" data-end=\"828\">metal alloy<\/strong> which is not found in nature in its pure state. In its essence, it is <strong data-start=\"909\" data-end=\"955\">yellow gold combined with white metals<\/strong>, such as palladium or silver, in order to modify its colour, physical properties and wear behaviour. This type of gold is widely used in jewellery, especially for wedding rings, engagement rings, earrings and pendants, because of its sophisticated appearance and durability.<\/p>\n<h3 data-section-id=\"ufbs1r\" data-start=\"1274\" data-end=\"1321\">White gold composition: the key elements<\/h3>\n<h4 data-start=\"1323\" data-end=\"1367\">1. <strong data-start=\"1331\" data-end=\"1367\">Yellow gold as the main base<\/strong><\/h4>\n<p data-start=\"1368\" data-end=\"1567\">The starting point for white gold is the <a href=\"https:\/\/joyeriagordillo.com\/pendientes-de-oro-amarillo\/\"><strong data-start=\"1409\" data-end=\"1425\">yellow gold<\/strong><\/a>, which provides the noble and valuable metal content of the alloy.

This plating is essential to give white gold its recognisable bright white appearance and to increase its surface strength.<\/p>\n<h4 data-start=\"2877\" data-end=\"2902\">Functions of rhodium:<\/h4>\n<ul data-start=\"2903\" data-end=\"3266\">\n<li data-start=\"2903\" data-end=\"3019\">\n<p data-start=\"2905\" data-end=\"3019\"><strong data-start=\"2905\" data-end=\"2925\">Improve colour<\/strong>The silvery-white hue we associate with white gold is largely due to this layer.<\/p>\n<\/li>\n<li data-start=\"3020\" data-end=\"3138\">\n<p data-start=\"3022\" data-end=\"3138\"><strong data-start=\"3022\" data-end=\"3044\">Increasing brightness<\/strong>Rhodium has a highly reflective finish, which gives a very lustrous appearance.<\/p>\n<\/li>\n<li data-start=\"3139\" data-end=\"3266\">\n<p data-start=\"3141\" data-end=\"3266\"><strong data-start=\"3141\" data-end=\"3167\">Protecting the surface<\/strong>As a hard metal, rhodium acts as a barrier to scratches, oxidation and fading.<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"3268\" data-end=\"3587\">It is important to note that this coating is not permanent. Over time, especially on frequently used jewellery such as rings, it can wear away, exposing the underlying alloy. It is therefore advisable to have a <strong data-start=\"3500\" data-end=\"3541\">new rhodium plating every few years<\/strong> to maintain the original shine of the piece.<\/p>\n<h3 data-section-id=\"14kzfzl\" data-start=\"3589\" data-end=\"3623\">Variability in composition<\/h3>\n<p data-start=\"3625\" data-end=\"4029\">Not all white gold jewellery has exactly the same mix of metals. <strong data-start=\"3705\" data-end=\"3789\">The composition may vary depending on the manufacturer and the type of jewellery.<\/strong>. For example, some fine jewellery brands eliminate nickel altogether to ensure a hypoallergenic experience, while others may adjust the proportion of palladium or silver depending on the desired colour and hardness.<\/p>\n<p data-start=\"4031\" data-end=\"4285\">This variability means that white gold can have subtle differences in tone between pieces from different sources. Some will be greyer, some whiter, and some with a slight warm tinge, depending on the exact proportion of each metal.<\/p>\n<h3 data-section-id=\"mi369w\" data-start=\"4287\" data-end=\"4314\">Advantages of white gold<\/h3>\n<ul data-start=\"4316\" data-end=\"4725\">\n<li data-start=\"4316\" data-end=\"4424\">\n<p data-start=\"4318\" data-end=\"4424\"><strong data-start=\"4318\" data-end=\"4339\">Modern elegance<\/strong>Its neutral and luminous tone makes it ideal for contemporary and minimalist designs.<\/p>\n<\/li>\n<li data-start=\"4425\" data-end=\"4597\">\n<p data-start=\"4427\" data-end=\"4597\"><strong data-start=\"4427\" data-end=\"4466\">Perfect complement to diamonds<\/strong>White gold: Unlike yellow gold, white gold brings out the brilliance of white gemstones without changing their perceived colour.<\/p>\n<\/li>\n<li data-start=\"4598\" data-end=\"4725\">\n<p data-start=\"4600\" data-end=\"4725\"><strong data-start=\"4600\" data-end=\"4623\">Versatility of use<\/strong>It goes perfectly with any skin tone and with other jewellery, be it gold, platinum or steel.<\/p>\n<\/li>\n<\/ul>\n<h3 data-section-id=\"mm3bdu\" data-start=\"4727\" data-end=\"4769\">Considerations when acquiring white gold<\/h3>\n<p data-start=\"4771\" data-end=\"4846\">Despite its many virtues, white gold requires some care:<\/p>\n<ul data-start=\"4848\" data-end=\"5302\">\n<li data-start=\"4848\" data-end=\"5011\">\n<p data-start=\"4850\" data-end=\"5011\"><strong data-start=\"4850\" data-end=\"4882\">Periodic review of rhodium<\/strong>On pieces such as rings or bracelets, where wear is higher, it may be necessary to re-apply the rhodium plating every 1 to 2 years.<\/p>\n<\/li>\n<li data-start=\"5012\" data-end=\"5158\">\n<p data-start=\"5014\" data-end=\"5158\"><strong data-start=\"5014\" data-end=\"5044\">Avoid abrasive products<\/strong>When cleaning white gold jewellery, it is preferable to use soft cloths and specific solutions for precious metals.<\/p>\n<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Cuando hablamos de joyer\u00eda fina, uno de los metales m\u00e1s populares y deseados es el oro blanco.
