Recently i found a platinum diamond ring i like. However, when i use loupe to look at it closely. I found there is dark line between prong and diamond, almost between every prongs and diamond. I don't think that dark line/stain is on diamond itself since the diamond clarity is VS1. I wonder if that is normal? If it is stain, is it removable? The other ring does not have it, but that diamond quality is not as good.

Thanks for your help in advance.

You may be seeing the reflection of the prong into the diamond.

Or perhaps whoever worked last on the ring did not clean it properly, or it has specks of dust trapped between the prong and the stone.

Chemically diamonds are extraordinarily inert little things. They don’t stain, even with deliberate effort. I’m guessing you’re seeing a reflection or perhaps dirt on either the stone or the prongs and a good start is a professional cleaning of the piece. Take it to your favorite jeweler and see what they can do for you.

Hi cyang!

Maybe you can post some pictures...
I think those stains can be removed, it's unusual for VS1.

If you're seeing it between every prong you're seeing either a reflection or leftover rouge from polishing. just means that the jeweler either didn't notice and/or was in a rush, and didn't properly clean the ring as best they could before giving it back. Go ahead and bring it back to your jeweler and ask they give it another thorough cleaning, just in case, and then have a look again. If you're still seeing something, chances are, you just have sharp eyes and are seeing a reflection if you can't see it at all when holding the ring at a normal distance (ie, if it were on your hand and you were looking at it normally--not 2 inches from your eye--you really have nothing to worry about

Good luck!

I don't see it with the other ring (same style). Therefore, likely it's not reflection. I care about this ring since both color and clarity is better than the other one.

The ring is sold in a big whole sale store. They don't clean or resize. They have lenient return policy. But I just want to make sure it's not some tarnish which require some heat process to remove. After all, who want to go through those steps after getting a new ring?

Will the normal jewelry cleaning soltion (from walmart) remove the black line? If so, I will buy the ring without being too carefull.


Thanks

Before you buy--is the diamond GIA or AGS certified as VS1? If not, make sure you're not paying for VS1 and actually getting SI1 or SI2. How lenient is their return policy? Do you have a local jeweler that you trust to have a second look at the ring for you if you do purchase it?

Again--if it's all the prongs, you might have nothing to worry about. Rouge is kinda tough stuff, and cleaning solution alone won't get it off--you'll need liquid dish soap (nothing with any grit or conditioners--you don't want to scratch the ring, or give the diamond anything "greasy" to have attract dirt) and a soft-bristle toothbrush and warm water. Just give it a little scrubba, scrubba, and then have a jeweler take a second look at it. If they give it a thumbs-up as ok and that those aren't inclusions you're seeing--congrats! you got yourself a ring! If they aren't happy and neither are you, then take it back and come back to us if you need any other advice!

(oh...and if you get the ring, come back and show us pictures, k? )

Good luck and congrats!

Hello Cyang,

Take it to a store that has a Gemologist/Appraiser, Microscope, and competent jeweler on staff. We can tell you what you should do but we're guessing. However, they can look at it and make any corrections that are needed. Sounds like the seats were poorly cut and you are seeing reflections.

There I go guessing again, just take it to a professional.

Good Luck,

Jim

Sounds like it could have some polish stuck between the stone and prong area. Have them give it a thorough cleaning again.
