What is Black Gold?
Black Gold refers to genuine gold (commonly 18K or 22K) that has been treated to achieve an intense, matte-black or glossy black finish. It's not found in nature—rather, it's created using advanced techniques such as electroplating, alloying, or surface structuring.
How Is Black Gold Made?
Several methods are used to produce the signature black surface:
- Electroplating with Black Rhodium or Ruthenium - A thin metallic layer is applied to the gold, giving it a glossy or matte black tone. This aesthetic finish, however, may wear over time and require re‑plating.
- Alloying with Cobalt or Chromium - Heat treatment on alloys such as 75% gold + 25% cobalt forms a durable black oxide layer. Some combinations (e.g. Au-Co-Cr) yield improved wear resistance and deeper shade.
- Femtosecond Laser Surface Structuring - High‑energy laser pulses create nanostructures that absorb light, producing an intensely deep black finish. This method ensures lasting durability but is more costly and high-tech.
Is It Real Gold?
Yes. The core material remains authentic 18K or 22K gold, retaining its intrinsic value. The black hue results from surface treatment or alloying—it doesn’t dilute the gold purity.
How Much Does Black Gold Cost?
Pricing depends on:
- The karatage of the base gold (e.g. 18K, 22K)
- The complexity of the blackening process (electroplating vs laser treatment)
- Design intricacy and brand reputation
Typically, Black Gold jewellery may be priced comparably or slightly above standard gold jewellery, owing to its finishing techniques

Care & Maintenance Tips
To preserve the integrity and color:
- Use soft cloths and mild soapy water for cleaning
- Avoid abrasive materials, chemicals, and perfumes
- Separate storage prevents scratching the coated surface
- Consider periodic re-plating for electroplated pieces to restore original finish
Authenticity: How to Verify Black Gold
- Confirm presence of hallmarks and purity stamps (e.g., 18K750, 22K916) including BIS hallmark where applicable.
- Ask for certification from retailer, especially detailing the method used (e‑plating/alloy/laser)
- For uncoated alloy types, ensure professional evaluation or assay
Black Gold vs Other Colored Golds
Type | Description | Durability & Care |

FAQs on Black Gold
- Is black gold real gold?
Yes, black gold is made from real gold - usually 14K or 18K. The black appearance comes from plating or alloying with other metals, but the base remains authentic gold.
- How is black gold made?
Black gold is created by either:
- Plating yellow or white gold with black rhodium or ruthenium
- Alloying gold with cobalt or chromium and applying heat treatment
- Does black gold fade over time?
If black gold is plated, the surface color may fade or wear off with regular use. Alloy-based black gold is more durable. Proper care can prolong its appearance.
- Can black gold be resized or repaired?
Yes, black gold can be resized or repaired by a professional jeweller. However, plated pieces may need to be replated after resizing to restore the finish.
- Is black gold more expensive than yellow or white gold?
Black gold is generally priced similar to yellow or white gold of the same karat weight, but may cost slightly more due to additional treatment or design work.
- Is black gold suitable for daily wear?
Yes, but with care. While black gold is durable, the plating can wear down faster with rough use. Avoid harsh chemicals, and store it properly to maintain the finish.
- Can black gold be hallmarked?
Yes. Since the base is real gold, black gold jewellery can carry a BIS hallmark (in India) or international purity certifications based on the karat used.
