How can I upgrade from 18ct Gold to Platinum?<\/span><\/h2>\n\n\n\n

This is not something you should feel is necessary. <\/span><\/p>\n\n\n\n

18ct Gold is a beautiful metal<\/a> and remains very popular for engagement rings and wedding rings.<\/span> <\/p>\n\n\n\n

However, many consumers have decided to replace jewellery by redesigning items made in platinum. <\/p>\n\n\n\n

What is the cost of changing a ring from 18ct Gold to Platinum?<\/h2>\n\n\n\n

Based on the 2026 prices of Platinum and 18ct Gold, we assessed the cost of converting a ring mount from Gold to Platinum. Although Platinum weighs just over a third heavier, the price per gram has risen into 2026. For this reason, the cost is lower than Platinum at this time.<\/em><\/p>\n\n\n\n

Based on January 2026 prices for a single-stone (solitaire) ring mount and moving a diamond from one metal to the other metal.<\/p>\n\n\n\n

Price for new \u00a318ct Gold ring mount (3 grams x 18ct Gold price) = \u00a3750<\/p>\n\n\n\n

Price for new Platinum ring mount (3 grams x 1.34 heavier weight = 4 grams x Platinum price)= \u00a3690<\/p>\n\n\n\n

Scrap price for the unwanted 18ct gold ring = 3 grams x \u00a335 per gram = \u00a3105<\/p>\n\n\n\n

Price for new Platinum mount \u00a3690 less scrap \u00a3105 price = \u00a3585.00<\/strong><\/p>\n\n\n\n

The price will depend on the chosen design’s weight, but this calculation shows the price difference for a 0.30-carat solitaire ring when changing the precious metal to Platinum. There would also be a small additional price (\u00a325) to set the diamond into the new ring.<\/p>\n\n\n\n

***Please remember that a bespoke ring design will cost 2-3 times this amount due to the CAD design work required and the custom build of the ring. <\/em><\/p>\n\n\n\n

Why upgrade 18ct White Gold Jewellery to Platinum<\/span>?<\/h2>\n\n\n\n

Why, then, would someone want to upgrade from 18ct Gold to Platinum?  <\/span><\/p>\n\n\n\n

Many consumers observe a gradual tarnish on their white gold jewellery over time. Besides scratches, white gold loses its Rhodium plating. <\/p>\n\n\n\n

Furthermore, the inconsistent colour between the metal body and the Rhodium plating may be noticeable to others. <\/span><\/p>\n\n\n\n

As the Rhodium plating wears<\/a>, the natural off-white colour of gold reveals itself. For this reason, some buyers feel disappointed in a change of appearance. However, this is completely normal for 18ct White Gold. <\/span>All jewellers apply a Rhodium plating to white gold. <\/p>\n\n\n\n

Upgrading an engagement ring owing to size issues<\/span><\/h2>\n\n\n\n

Some buyers upgrade from 18ct White Gold to Platinum due to size issues. If your ring cannot be resized, it might need to be remade. For this reason, some clients seize the opportunity to remake their ring in Platinum. <\/span><\/p>\n\n\n\n

The difficulty arises when additional wedding bands are present in the original metal. As a result, this can be more costly when more rings are involved.\u00a0<\/span><\/p>\n\n\n\n

Our example below shows a Platinum half eternity ring<\/a> upgraded from 18ct White Gold owing to size issues. <\/span><\/p>\n\n\n\n

After removing the diamonds, our video clip shows the old 18ct White Gold ring mount. The final ring shows the finished Platinum half-terternet ring.<\/p>\n\n\n\n
