    why is it called the weekly opal deal when it is the same opal every week?

    • Blackopaldirect

      Hmm good question Brian :-/

  • Christine James

    What type of polish are you using with the dremel? I’ve been searching online and can’t seem to find a paste. Thanks.

    • David Sahadi

      Just like Justin uses……you can buy Cerium Oxide from any rock shop or look on eBay. I use to use felt wheels that work on a dremel tool. Make a paste from the cerium oxide and water and apply it to the felt wheel. Works like a charm giving to a beautiful 20,000 grit polish. If you really want to get crazy you can get about six felt wheels and use diamond paste, graduating the grits up to 100,000. You need to make sure you segregate the different wheels and clean up after each grit. I’ve done it but it is a little extreme. Now in either case this is assuming you have shaped and have gotten out scratches using sanding wheels that are available for a dremel tool. Good luck!

    • Blackopaldirect

      Sorry for the slow reply mu goodness I’m on it now :-/ Yes David is right. You can buy them from many places online or lapidary shops. ebay and shelleys lapidary is a great place to buy but you can get it closer to your country if you would need less shipping and faster service. Thank you for answering Christine, David. 🙂

      Hi Christine, Did you find the polish you wanted? I just saw your comment, I don’t come here too often. I bought some diamond polish paste on eBay, it works much better than Cerium Oxide I have both CO and diamond polish and the paste will really dazzle you. As a matter of fact I put it on some opal I bought that were polished with Cerium Oxide, but it looked like they were dull. I re-applied Cerium Oxide, but still wasn’t to impressed. I put a dab of the felt wheel of my Dremel and got amazing results. I don’t waste my time with Cerium Oxide now I just apply paste and am very pleased with the out come.
      Weather using Cerium Oxide or the diamond paste you need to take proper protective measures, both are Carcinogenic and should be used with latex gloves and a surgical mask and eye protection. opal shards can fly off the opal and damage your eyes. Also with Cerium Oxide is it is mixed with water and has to be constantly re=applied. The paste are oil based and a small amount on the Dremel felt disk (about 1/8 inch and will spread all over the disk polishing edge. It comes in syringes and is very easy to apply a thin line. A small amount will polish an opal or two. and you get about 12 different grades for different items hardness, they are different colors for each grade and marked with the fineness. Some go as fine as 0.5 mcg. which is finer than 500,000 grit or finer. It can be used to remove scratches from gold, silver platinum jewelry and make it look like new. Cerium Oxide has to be re-applied every 15 seconds or so as it dries out, when it is dried on the spinning disk, it spreads Cerium Oxide dust all over the work area, as I said it is carcinogenic and the dust if not cleaned up will end up all over the work area and can cause cancer of the lungs and airways, vocal cords, and mouth. It is widely used but nobody tells you it can kill you or others that are in the polishing area. The paste being oil based stays on the felt disk of Dremel’s. Most opal cutters that sell cut in volume and there polishing disk is re-applied by a drip system or routinely re-applied to prevent dust problems.

      • Christine James

        Thank you. No, I didn’t find anything, but this is the first time I’ve seen the answers written here. I stopped working on the opal at that time. After cleaning it with water and the dremel, it dried and I can no longer see the colors. I’m confused and don’t know what to do. You could see the colors before cleaning it, and it said you have to clean it wet because it’s so soft, so I did, but now it’s just a white rock. 🙁

        • Blackopaldirect

          HI Christine Are you cutting Ethiopian opal to cut as that type does go clear once wet. You really should practice with Australian opal as it wont change. 🙂

          • Christine James

            Yes, that’s what I have. It was my first piece. I saw it online and thought it was beautiful so decided to give it a try. Thanks for the tip, maybe I’ll try the Australian opal instead. 🙂

          • Blackopaldirect

            Yes Australian opal will not change like the Ethiopian stuff. Worth trying though so you can learn from it. 🙂

        • Casey

          All crystal opal dry out and turn whitish color. You needs to soak them in water for a week, or longer. This in no way hurts the opal as opals have the highest water content of any stones. If they turned white, as most opal do, you need to polish them with “Diamond Paste”. it can be bought on eBay for under $20. Put a small dab on a Dremel buffing pad. They should come out very nice. (If not send them back.

        • Casey

          The opals are Coober Pedy opal from Australia, made of silicon dioxide and have a water content of 6% to 20%. They need to be soaked in water to bring out the colors, dried and polished with diamond polish. Mine came out great. Especially the chocolate opal I got from Mexico. I had to cut it out of a small meteor that was nickel steel. It took three days to remove the 3 opals, only one made it to final polishing.
          Imagine that you have an opal that came from the Oort Cloud, some 50,000 to 200,000 AU away, or 0.8 light years to 3.2 light years away.. Since we can’t use warp drives that can do light speed is took approx.299,792 meters per second, that means it took millions of years to fall in Mexico. But it’s a great chocolate opal with streaks of red fire, magenta, green, orange and yellow and finishing weight is 5ct.

        • Casey

          Hey Christine, Coober Pedy opal are very expensive, Their the ones that are sold in jewelry stores. 🙂

        • Blackopaldirect

          Hi Christine you now cant see the colors because you have bought Ethiopian opal and it is volcanic. Australian opal does not do this. Let me know the type you are working on.

    • Casey

      Try eBay, search under diamond paste. I got 12 syringes with about 1 to 3 mL of paste. Each syringe has a different grit ( for lack of a better word) starting at 40. all the way to 0.5. 0.5 will make your gems sparkle like diamonds.

      HI Daniella We seemed to have missed this message. I am really sorry for that. I think you have already bought now as time has gone on. I have had a glitch on the blog and have not been getting notifications. I am now on top of it and will answer all of your questions you have from now on.

  • Colton Simianer

    Hey can anyone help me out were would be the best place to sell your opal it seems so hard right now thanks anything would be of help

    • Hi Colton The best places are to start with an Etzy store. The main thing is to get a presence out there in the world and then people start to trust you. Jeweller stores are also great to start with. Ebay will be a good learner for you as the honesty system on there teaches us all about good customer service. The only thing is the fees are horrendous. I guess you really need to pick a place to sell and stick to it as people will know your there and come back when they think of opal. I hope this helps Regards Justin

    • richard barrett

      what I do Cotton, is take photo’s of the stone when I first get it looking like a rock, and the a few other’s as it becomes a gem, Then I send the photo’s to all friend’s and relatives, and when they are amazed They share them, after setting I do the same thing, It’s slow but you build an interested cliental, It really amazes people to see a gem come from a rock

  • richard barrett

    keep in mind that you will want to KEEP water on the wheel with a dremel, the felt will dry very quickly and burn the stone, with the larger you get about 20-30 seconds, before needing water dremel maybe 10 seconds

  • Andre

    Hello, I’m thinking of purchasing 76 ct rough opals but I would like to know how long would it take to get from Australia (or wherever it is exported from) to South Africa.

  • Jason

    Hi Justin, I am curious about Crystal Opal. I have been starting to learn to cut opals from Ridge potch scraps that have exposed a few surprises but one in particular was what I call ‘Ugly Blue’ As I started to get some of the solid potch off I realised that the bulk of the stone is actually quite translucent and opaque with little colour until it comes under extreme white light and then the thing just shines. I was wondering if you can confirm by the attached 4 pics (will attempt to upload 4 pics) whether it is likely to be a Crystal Opal. Estimated weight at this stage is about 15 carats. Still a work in progress, still learning.

    • Jason

      The last pic doesn’t show the preview but if you click it, it will show.

      Dear Madam/Mr,

      We are looking for partner in building a local mining company or
      serious cash buyers of Au Gold and rough/uncut Diamonds, my father
      and others are local sellers and miners of Gold and Diamonds here in
      Guinée, they want to get money to help our families as you know here
      in Africa we have many people in our families, they are counting on
      some people who went to school to help them but these people just want
      to steal their products even the government promised to help our
      community but since my father gave them products they’ve been just
      telling story every day, every time. This is the reason why our
      community decided to contact the good people.

      Due to the way they are mining their products many people are trying
      to teach them because they don’t know the world market even some
      mandates and buyers rep have come and carried their products on
      credits and they have never come back to pay their money. So right now
      i want to get them serious people who can help them to sell their
      products following the market. At the moment they have GOLD DUST/BARS
      and ROUGH/UNCUT DIAMONDS in large quantities for sale at cheap price.

      They need people like you, people over there to help them develop
      their goal, so that they can help our community, because people sicks
      and dies because no money. They have the products but they are very
      poor here because of the way the government and some people are
      treating them, they want serious buyers to be their eyes and
      mouths,they are ready to give you goods if you are serious and ready
      to open a local mining company with them to work together and help
      them and you in mutual benefit or help them buy their products so
      that they can at least buy mining equipments such as, bulldozers,
      tractors, excavators, wheel loaders, backhoe loaders, motor graders,
      dump trucks, crushing equipment, and etc as we need to enhance our
      mining productivity. We will give you good price far below the word
      market price.

      Hope to hearing from you soon.

      Thank you,

  • Burnham

    Hi Justin, just wondering if these sorts of opal are valuable or not compared to opal with big patches of colour? The opal type I mean are the jet black ones that have dots of colour appearing on the face at certain angles – so you mainly get the feeling the opal is basically black, but it does have colour when moved around in the light? This particular one 3.5ct.

    Thanks Justin!

  • Louise Taylor

    Hi, I have this gorgeous ring that i have had for 12 years but i am unsure as to whether this is a genuine opal. Is it possible to tell from this photo?

    • Richie

      It is a pretty ring.
      From only the one picture to go on and limited history of the ring, it looks to me to be a created Opal and not natural. The pattern looks too organized and the shapes of the color patches not natural.
      Can you see the edges or the back of the Opal? How does the play of color look to you when the ring is rotated and at different angles in different light? Can you see any inperfections in the stone regarding tone, color, etc.? Does it look too perfect?
      Is the metal silver*, gold, etc., and what was the approx. cost of the ring 12 years ago and where is its origin, if known?
      As I mentioned, determining for certainty as to whether the Opal is natural or not is based on limited information from a picture alone.

      • Louise Taylor

        I can’t see the back of the stone due to the setting, but it looks like this on the sides too. I paid about $120 USD for it. It’s very perfect and uniform which is what made me think this is created.

        • Richie

          Your first impressions are important. And your confirmation of uniformity and being very perfect add to the total picture.
          I’d say it’s safe to say it is created, which of course doesn’t take away from the beauty and enjoyment of your ring 🙂

          • Louise Taylor

            Thank you. Thats what i thought. Disappointed as I was hoping it was real. Thank you for your help 🙂

          • Richie

            Of course I cannot be 100% certain for the reasons I previously gave, although I’m pretty sure.
            You can also look around the Web for pictures of synthetic, stimulants, etc. to see photos for reference. And of course the natural Opals on this site to see the differences.
            You can always bring the ring into a knowledgeable jeweler to be sure, if you still have any doubts.

          • Louise Taylor

            I’m pretty certain you are right. It is far too perfect and for a stone this size it should have cost in the thousands I would imagine if it had been real. I’ll have to start saving up for a real one 😉

    • Guest

      I have a few opals that look exactly like the one pictured. There beautiful stones, but unfortunately their man made, counterfeit opal. Don’t let it get you down, I bought mine because I loved the colors in the opal. There were a lot of them on eBay a few years ago. I just hope you didn’t spend too much for the ring. As long as your happy, its all that counts.

    • Blackopaldirect

      HI Louise Yes the opal is a synthetic opal. Sorry for the slow reply somehow it passed me by
