Is Purple Gold Real? Guide to Purple Gold Rings and Jewelry
Dhanlaxmi Trade Desk · 2026-10-23
Yes, purple gold is real gold: an alloy of about 79% gold and 21% aluminum, sold as 18K or 19K. It is too brittle to bend, so jewelers cut it like a gemstone and set it into gold or platinum rings, pendants, and earrings.
Key takeaways
- Purple gold is about 79% gold and qualifies as 18K.
- Its violet color runs through the metal; it is not plating.
- It is brittle, so it is set or inlaid in gold or platinum.
- The purple gold part of a ring cannot be resized.
- It costs more than the standard 18K of the same weight
Purple gold is one of the most searched colored golds, and buyers ask the same questions every time: is it real, can it be worn every day, and why does it cost more? Here are straight answers for retailers and designers thinking about adding purple gold jewelry to their range.
Is purple gold real gold?
Yes. When gold is melted with aluminum in the right ratio, the two metals form a compound called AuAl₂.. That compound is naturally violet, so the color runs all the way through the metal. It is not a plating or a coating, and it will not wear off. At about 79% gold, it meets the 18K standard, and some makers stamp it 19K. You may also see it called amethyst gold or violet gold.
Many cheap "purple gold" listings online are plated or coated base metal. Real purple gold carries a karat stamp, and a reputable maker will confirm the composition in writing.
How purple gold jewelry is made
Purple gold is hard but brittle. Ordinary gold alloys bend; purple gold behaves more like a gemstone, and a sharp knock can crack it. So jewelers rarely make a whole piece from it. Singapore jeweler Lee Hwa launched the first commercial purple gold jewelry in 2000, and its parent company Aspial patented the process by 2002.
- Cut and polished like a gem, then set in a bezel of yellow gold, white gold, or platinum.
- Used as an inlay in a band, protected by gold edges on both sides
- Cast in small batches with tight temperature control, because rejects are common
Purple gold rings, necklaces and earrings: which designs work
- Purple gold necklace and pendants: the safest choice, because they take the fewest knocks.
- Earrings: studs and drops in a gold or platinum frame
- Purple gold ring: an inlay band or a purple gold "stone" set in a bezel, not a thin all-purple band
- Stone pairings: white diamonds for contrast, lab-grown diamonds to keep the price sensible, and amethyst or tanzanite for a tone-on-tone look
Purple gold vs rose gold vs white gold
- Gold content: purple gold is about 79%; rose and white gold are 75% at 18K or 58.5% at 14K.
- Color: purple gold from the gold-aluminum compound, rose gold from copper, white gold usually from rhodium plating
- Workability: rose and white gold can be bent, soldered, and engraved; purple gold cannot.
- Everyday wear: rose and white gold suit daily wear; purple gold suit pendants, earrings, and protected ring designs
Can a purple gold ring be resized?
The purple gold itself cannot be resized; bending or heating it can crack it. If the purple gold is set into a gold or platinum shank, a jeweler can sometimes resize the shank, but only if the design leaves room. For custom orders, confirm the finger size before production and design the ring with a plain gold section at the back for sizing.
How much is purple gold worth?
There is no public price index for purple gold. Pieces are quoted one by one and cost more than a standard 18K piece of the same weight because of the high gold content, specialist casting and cutting with more rejects, and small production runs from only a few makers. For resale, the gold content sets the floor value, as with any gold jewelry.
Caring for purple gold
- Clean with mild soap and warm water, then dry with a soft cloth.
- Take it off for sport, gym, and heavy work.
- Store each piece separately in a soft pouch.
- Wipe off sweat after wearing, because it can dull the surface over time
Should you add purple gold to your range?
Yes, as a statement line rather than a bestseller. Start with pendants and earrings, set the purple gold in a protective gold or platinum frame, and use white diamonds for contrast. For the science behind the metal, read our first guide: Purple Gold: The Rare 18K Gold Alloy.
Frequently asked questions
Is purple gold real gold?
Yes. Purple gold is an alloy of about 79% gold and 21% aluminum, and its violet color runs through the metal rather than being plated on.
Is purple gold 18K?
Yes. At about 79% gold, it meets the 18K standard of 75%, and some makers stamp it 19K.
Can you wear a purple gold ring every day?
Only a protected design, such as an inlay band or a bezel-set piece. A ring made only of purple gold is too brittle for daily wear.
Does purple gold fade or tarnish?
The color does not fade because it runs through the metal. The surface can scratch or dull with sweat, and a jeweler can polish it back.
