This will teach you how to make a heart out of a small-ish stone or rock (if anyone can tell me the difference between the two I'd really appreciate it). These have many uses and the one shown in this Instructable is going to be made into a pendant (don't worry, I'm going to write an Instructable for that too).

Step 1: Gathering Materials


Gathering Stones

You want to find a stone with a roughly triangular shape, and a disirable color. I'm not going to tell you where to find stones because that would be insulting. Everyone should know where to find at least one stone or rock.

Gathering Tools

Your going to need a way to shape the stones. I recommend a 4" angle grinder with a diamond coated sawblade attachment. Most people who aren't familiar with tools are saying, "whaaa?" so I'll explain what they are and where to get them.

4" angle grinder

This is a tool used to grind metal, hence the "girnder" part of the name. It is designed to spin at the appropriate RPM (revolutions per minute) with a 4" blade or grinding wheel, hence the "4"" in the name. the "angle" bit isn't important. Youcan find these at any hardware store, such as home depot (I got mine at Harbor Freight). It'll probably cost about 30$ (U.S. dollars)

Diamond coated sawblade

This is a sawblade designed to cut/grind through glass and stone. The cutting edge is lightly coated with crushed diamonds. I use a drycut one in this Instructable. Again you can find this in almostany hardware store, such as home depot (again I got mine at Harbor Frieght). Expect to pay abou 15$ (U.S. dollars)

Step 2: Forming the "V" of the Heart


To form the "V" of the heart, simply grind away the unwanted parts. It may take some practice, so be sure to gather a few rocks.

Step 3: Forming the "m" of the Heart


Simply grind away the unwanted parts, just like you did with the "V" of the heart. you may want to practice on junk stones before hand.

Step 4: Finishing

This is an optional step. You can finish the stones by grinding the rest of the smooth stone away. This gives you a uniform surface to work with. You may then want to polish it, for this you have a few options, you can throw several of them in a tumbler, or you can sand them. I decided to sand it. The first time I tried this I used the tumbler option and got decent results. The second time around I hand sanded it and got better results. You only need to use one grit of sand paper: 100 grit.

NOTE: I realized that when the stone heart got wet, it looked like it had been polished. Knowing that, I decided to oil it. I couldn't use just any oil, it had to be able to soak into the stone so it would stay permanently, but it couldn't make it slimy. My solution: mineral oil. I choose it because it soaks into things very well, and is widely avaliable. "But, Iv'e never seen it in a store..." yes you have, look at the ingredents in baby oil: 99% mineral oil, 1% fragrance (I know thats not the actual percentages, I'm going off memory). So I made another heart, and coveredit in baby oil, it's working great, I'll have to see the long term results before I put up a picture though...

If you want to put this on a necklace, follow my next Instructable: Stone Heart Pendant.
do you think a Dremmal tool with the right attachments would work?  Your heart is beautiful!
OK Stones and rocks exactly the same things. Stones are deffinately not all sedimentary. (Think of diamonds, rubies, etc. commonly referred to as stones.)<br/><br/>You got incredible results with that angle cutter. GRRRRR hundreds of dollars (probably thousands if I am honest) of equipment and tools, including flat lap, flex shaft, portable wet diamond grinder, etc. I don't think I could do as good a job as you did.<br/><br/>Your blade will last longer if you always keep it wet. Diamond easily over heats and gets pulled out of the metal holding it. = Wrecked blade.<br/><br/>Sanding - if you use wet dry sandpaper, you can put some water on a tray and rub the stone back and forth. I'd go one by one up a few grades to 400 or 600. The smoother it is, the longer your oil is going to keep it looking good.<br/><br/>Mineral oil. Its in the pharmacy section. Cheap, works ... Oil of various kinds has been used for hundred's of years to make stones look better. It is commonly used on emeralds and probably many other precious stones.<br/>Some people say its cheating, but it is a very universal treatment.<br/><br/>Put your stone into a cup of it and leave it for a day or two. Then take out and wipe it off with a soft cloth. You can retreat the stone later if you need too. We have some delicate pseudomorph agates that we would not want to subject to the stresses of polishing. We just soak it good before displaying it. <br/><br/>With hearts like that to impress the love of your life, you will never need diamonds except to polish rocks.<br/><br/>Merry Christmas!<br/>
Well the blade lasts a long time reguardless (at least mine does), and I'm too cheap too buy a pump (actually too broke...), but thanks. As for the sandpaper, the rock dulls down the sandpaper gradually so in the end I was probably working with at least 300 or 400 grit, and the water thing... well i usually did the sanding while bathing... problem solved (kinda...). Thanks though, I appreciate all the advice i can get.
That's a pretty damn good job for using a grinder and sandpaper.
I second that.
Thx.

I think the geological definition applies to minerals and ores and the metallurgy definition applies only to metal.
Scroll down - there's a table of sizes, describing exactly what <em>pebbles</em> or <em>boulders</em> are.<br/>
Ah, I see. So what two things would you like to know the difference between?
Thx again.
From what i remember of really boring science lessons (never covered this in geography), the stone/rock argument is how the stuff is formed, and the size. Rock is the really hard stuff, formed in volcanoes, and the surrounding areas. stone is formed by sedimentation (debris like sand and particles collecting together), and being pressurised into a single entity. I think......
Interesting.
Im afraid now... its a great nstructable - thats not what im afraid about. Your exactly like a friend of mine but your not him >_> Both the same name (Conor but you have 2 N's) you both have a fraid named scott and both of these friends named scott always call themselves Mr.Sexy (In one of your instructables "- Thanks to Mr. Sexy Scott because connor is too lazy to type" or something along those lines) You both go to harbor freight alot, the same dresser, Same age, same intrests, This part is based on your icon - your both interested into Anarchy... >_> Its weird
LOL, dude if you were serious that would be awesome, but I've never met anyone named scott. Like I said, Scott J. Fox is his psuedonym (10$ says I spelled that wrong), his fake name.
Oh i didnt hear that before :P I Am serious about what i said though. Its very creepy...
Hmmm, thats interesting, Where do you live?
By the way, you were close. A Google search resulted in PsEUdonym.
Wow, I just guessed on how to spell that. I guess you owe me 10$ lol jk.
