Upgrading from 18ct White Gold to Platinum Jewellery

Upgrading from white gold to platinum

How can I upgrade from 18ct Gold to Platinum?

This is not something you should feel necessary to do. 18ct Gold is a beautiful metal, and remains very popular for engagement rings and wedding rings.

Reasons for upgrading 18ct White Gold Jewellery to Platinum

Why then, would someone want to upgrade from 18ct Gold to Platinum?  This is usually down to an observation over time. The inconsistent colour between the body of the metal and the Rhodium plating may become visible over time. 

As the Rhodium plating wears, the natural off-white Gold colour appears. For this reason, some buyers feel disappointed in a change of appearance. But this is completely normal for 18ct White Gold. 

Upgrading an engagement ring owing to size issues

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. 

Difficulty comes when additional wedding bands exist in the original metal. As a result, this can be more costly where more rings are involved. 

Our example below shows a Platinum half eternity ring upgraded from 18ct White Gold owing to size issues. 

Our video clip shows the old 18ct White Gold ring mount after unsetting the diamonds. The final ring shows the finished Platinum half eternity ring.

Upgrading to Platinum owing to damage done to the original ring

Damaged beyond repair, some clients choose Platinum for a replacement engagement ring. This could be the perfect opportunity to upgrade from 18ct White Gold to Platinum. 

Upgrading a wedding ring to Platinum due to wear

Sometimes detail wears away over time. For example, hand engravings. Platinum offers a more durable surface for patterns and engravings. We upgrade wedding rings in Platinum with the same detail. For example, hand engravings. Our example below shows a wedding ring upgraded to a new Platinum replica of the ring.

Upgrading Yellow Gold to Platinum

Some mature clients decide to modernise their jewellery. The whiteness of Platinum gives a contemporary feel. Some couples upgrade from Yellow Gold to Platinum to add a more contemporary feel to their jewellery.

A damaged setting might enable us to use your existing shank. To explain, sometimes we replace an 18ct White Gold setting with a Platinum setting. We mount this onto our client’s original band.

18ct White Gold and Rhodium Plating

Once polished, 18ct White Gold tends to appear naturally tinted or off-white because of the 75 percent pure gold content. 18ct White Gold is mixed with other metals. 

Most people realise that pure Gold is Yellow Gold in colour. Alloyed with other precious metals, different alloy metals give it a paler colour. 

This can be said of both 9k, 14k and 18k Gold. In the UK we seldom work with 14k Gold. We create rings in 9k or 18k Gold instead. 

The final stage of finishing involves plating the item with Rhodium. Rhodium is a very hard, ultra-white metal, in the same family as the Platinum group. 

Jewellers apply Rhodium by plating once the ring has been polished. This gives the surface a regular white finish typical for 18ct White Gold.  

Many people incorrectly attribute the colour change to the actual metal tarnishing— a common misconception. 

The wear becomes evident where the ring comes into contact with everyday items over time.  

Owing to the natural white colour of Platinum, it makes the perfect choice for jewellery. 

Which is better – 18ct White Gold or Platinum?

For the answer to this question, we covered things in more detail in one of our alternative blog posts.

Benefits of a Platinum engagement ring

Positive characteristics of Platinum include natural whiteness (no Rhodium), and the ability to be refurbished. 

Re-polishing restores the mirror like surface of the brand new ring. Also, the intrinsic value, allergy-free properties, and rarity. A further attraction includes a luxurious feel from being a third heavier than 18ct Gold.

Gold vs Platinum for ring settings?

Which is better for holding diamonds? A Gold setting or a Platinum setting?

Platinum is generally regarded as the best metal for ring settings. 

More rigid, Platinum gives a holds diamonds with more strength. In addition, it requires no plating. Furthermore, Platinum is durable owing to increased density. 

A Platinum setting can be mounted onto a Rose Gold or Yellow Gold band. Or, many buyers order an engagement ring made entirely in Platinum.

How to upgrade to Platinum

So, with this in mind, how do you go about upgrading the same ring from 18ct White Gold to Platinum?  

The first approach involves a remake of an existing ring design, basing it on the same style, in Platinum. 

We include the cost of the metal from the existing ring. As a result,  we reduce the cost of the new ring. 

First, we work out the gram weight of your current ring. Then, we calculate the scrap metal price. Finally, we remove this cost from cost to upgrade your ring. 

Working with the original ring, we CAD design or hand-craft the new Platinum ring based on the exact same style. 

Or, some clients seize the opportunity to change their design altogether. Remember, you need to work around your existing diamonds. For this reason, choose a new design suitable for your existing gemstones.

One of our recent clients used their Gold solitaire ring, upgrading to a Platinum 2 stone ring design. We used her existing diamond, matching a new stone for the ring. We match diamonds by size, colour, clarity and cut. We provide the same service if a client would like a new ring with diamond shoulders.

Refurbishment costs for 18ct White Gold and Platinum Jewellery

The cost to refinish 18ct Gold and Platinum is very similar. Despite its hardness, Platinum scratches. From time to time, some clients send in their Platinum rings for repolishing. 

For this reason, decide how important it is to upgrade from 18ct White Gold to Platinum. The cost of refinishing your White Gold could cost less. 

For further information on this service, please just contact us through the website or get in touch directly by email.
