White gold and yellow gold are both valued using the same underlying principle — the actual gold content by weight and purity — but in practice, white gold jewellery often sells for less per piece than a similarly sized yellow gold piece. This isn’t because white gold is treated unfairly; it’s usually because white gold jewellery is commonly made in lower karat purities and involves a surface coating that has no resale value. Here’s the full picture.

White Gold Is Still Gold — Just Mixed Differently
White gold isn’t a separate metal; it’s an alloy made by mixing pure gold with white-coloured metals such as palladium, nickel, or silver, which neutralise gold’s natural yellow tone. The percentage of actual gold in the alloy still determines its karat rating — 18K white gold contains the same proportion of pure gold as 18K yellow gold. So at the same karat, the underlying gold content is identical between white and yellow gold.
Why White Gold Jewellery Often Sells for Less Overall
The price difference sellers usually notice isn’t about the gold itself — it comes down to two common factors:
1. Lower karat purity is far more common in white gold designs. Traditional Indian yellow gold jewellery is very often 22K, especially in wedding and everyday jewellery. White gold, on the other hand — especially in western-style engagement rings and modern designs — is typically made in 18K, 14K, or even lower. Since karat directly determines how much actual gold is in the piece, an 18K white gold ring naturally contains less gold per gram than a 22K yellow gold chain of the same weight, resulting in a lower payout for a similar-looking or similar-weight piece.
2. Rhodium plating adds visual value but no resale value. Most white gold jewellery is coated with a thin layer of rhodium to give it a bright, reflective white finish and to protect the metal underneath (since the natural colour of white gold alloy is often a duller grey-white without plating). This rhodium layer is extremely thin and holds no meaningful resale value — it’s cosmetic, not part of the gold content that gets valued when you sell.
Does Lower Karat Mean White Gold Is “Worse” Gold?
Not in terms of authenticity — an 18K white gold piece is genuinely 75% pure gold by weight, exactly as it should be for that karat rating, same as any 18K yellow gold piece. The lower payout compared to a 22K yellow gold piece simply reflects that less pure gold is present per gram of the total piece — it’s a purity difference, not a quality or authenticity issue.
How Is White Gold Tested When Selling?
The testing process is the same as for yellow gold — acid testing, XRF, or touchstone comparison to determine actual karat purity. The rhodium plating on the surface doesn’t interfere significantly with standard testing methods, since testing typically penetrates to or samples the underlying alloy rather than just the coating.
What About White Gold with Diamonds or Stones?
This is extremely common, since white gold is a popular choice for diamond-set jewellery like engagement rings and modern pendant designs. In these cases, the same principle applies as with any stone-set jewellery — the gold and the stones are valued separately, with the stone weight deducted before calculating the gold portion. If the stones are genuine and valuable, they may carry independent resale value beyond the gold itself.
Should You Expect a Lower Price Just Because It’s “White Gold”?
Not automatically — the fair comparison is always karat to karat. An 18K white gold piece and an 18K yellow gold piece of the same weight and tested purity should be valued the same for their gold content. The price difference people commonly notice comes from comparing an 18K white gold piece against a 22K yellow gold piece, which isn’t really a fair like-for-like comparison — it’s a karat difference showing up, not a “type of gold” penalty.
Comparison Table: White Gold vs Yellow Gold
| Factor | White Gold | Yellow Gold |
|---|---|---|
| Underlying valuation method | Weight × purity × rate | Weight × purity × rate |
| Common karat in Indian jewellery | Often 18K or 14K | Often 22K |
| Surface coating | Usually rhodium-plated (no resale value) | Typically no coating |
| Gold content at same karat | Identical to yellow gold | Identical to white gold |
| Common jewellery types | Engagement rings, modern designs | Traditional chains, bangles, wedding sets |
Why This Matters When Choosing Where to Sell
Since the real driver of price difference is karat, not colour, it’s important to have your white gold jewellery tested accurately rather than assuming it’s automatically worth less “because it’s white gold.” At Yellow Gold Point, every piece — white or yellow — is tested for its actual karat purity, so you’re paid fairly based on real gold content, not assumptions based on appearance.
Frequently Asked Questions
1. Is white gold worth less than yellow gold of the same karat?
No. At the same karat, white gold and yellow gold contain identical proportions of pure gold and are valued the same way.
2. Why does my white gold ring seem to sell for less than my yellow gold chain?
This is usually because the ring is a lower karat (like 18K or 14K) compared to the chain (often 22K), not because white gold itself is worth less.
3. Does the rhodium plating on white gold jewellery add to its selling price?
No, rhodium plating is purely cosmetic and has no resale value — it isn’t factored into the gold valuation.
4. Can white gold be tested the same way as yellow gold?
Yes, the same standard testing methods (acid, XRF, or touchstone) are used to determine purity for both.
5. Is white gold jewellery with diamonds valued differently from plain white gold?
The gold and diamonds are assessed separately, similar to any stone-set jewellery — the stone weight is deducted, and genuine diamonds may carry independent value.
