Clients frequently ask me if I can design jewelry for them made in 黑色 金. When I try to explain that 黑色 金 jewelry just isn’t a thing, they often send me advertisements from websites that offer it.
When a jewelry company advertises “black 金,” this should raise a red flag.
What Some Manufacturers 唐’t Want You to Know
What many buyers don’t realize is that the “black 金” rings and pendants they see online are either CAD images or pictures of 金 rings plated with 黑色 rhodium. Sellers attract buyers with these eye-catching images and leave the “black rhodium plated” part in the fine print.
Other sellers may be more transparent about their use of 黑色 rhodium, but they often do not mention how quickly the 电镀 will wear off.
Does this mean you should not buy 黑色 rhodium plated “black 金” jewelry? Not necessarily – but there are a few things you should keep in mind.
While a good pink temporary hair dye and a good rhodium 电镀 alike wish to be long-lasting, neither is permanent. Both will fade and will need to be recolored in order to maintain the desired look. In the case of rhodium 电镀, you also have scratches and scuffs to worry about, which will expose the 金 underneath.
A 黑色 rhodium 电镀 will generally cost between $75.00 to $120.00. If you want to just 黑色 rhodium plate a portion of your ring it may actually cost more than 电镀 it in its entirety. This is because we have more prep time to mask off the portion of your ring to be left in its original natural color.
The ring above, is a rose 金 hand engraved wedding band with 黑色 rhodium on the center. It is an excellent example of why a little 黑色 goes a long way. 通过 leaving part of the ring in the original rose 金 the 黑色 area is much more interesting.
Another reason this partial 黑色 rhodium is better than total ring 黑色 rhodium 电镀 is because it can nestle nicely in the detailed recesses giving a longer lasting 黑色 detail. If this ring had a total 黑色 电镀 all over it, the shiny edges would have worn off much more quickly and not in a pleasing way.
A well-done 黑色 rhodium 电镀 can really make your jewelry “pop.”
如果看到“black 金” style online that you just love, find out if they can email you a picture or two of an actual finished ring. This will let you see 真实的东西 and not just the idealized CAD Computer Aided Design image. Their description should explain how they achieve the 黑色 look; check to see if it mentions 黑色 rhodium.
If you love the look of 黑色 rhodium and understand its limitations, I say go ahead and get it! If you plan to order a 黑色 rhodium plated ring online, you should first make sure that there is a jeweler in your area who can re-plate it. That way you’能够保持其独特性’ look!
I recently saw this used bracelet with various chips and dings in the 黑色 links. We were unable to do anything to the 黑色 links except steam them as they were PVD coated. I discuss PVD coating in the post, 电镀与PVD涂层. It describes the differences and may help you make a choice if you are searching for a 黑色 or partly 黑色 look for your jewelry.
Other 黑色 details on jewelry besides 黑色 rhodium are oxidation and 黑色 enamel. See my blog:使用氧化，黑铑和黑珐琅制造黑色珠宝.
“So 黑金 Isn’t Real?”
科学家最近发现了一种 method for turning nearly any metal 黑色, making 黑色 金 a reality! 通过 using a high-power laser to focus huge amounts of energy on a tiny spot of metal, researchers are able to create microstructures that capture nearly all light that falls on the metal, turning it pitch 黑色.
飞秒激光技术价格下跌时，我们’ll have 黑色 金. But for now we have 黑色 rhodium and a couple other non-permanent techniques. If someone tries to sell you 黑色 金, it’s a fiction. If they try to sell you 黑色 rhodium plated 金 or platinum, it’s a fact!
