Must you always "Pre-Polish" your jewellery & WHY? 14 photos

 This little machine has given me much enjoyment during the past 5 years. It has cleaned many large and delicate jewellery items.

 These little steel pins are what this machine uses in cleaning the jewellery.

 From an extremely large, non-gold item as this tiger's face, anything will get cleaned by these 'tumbling pins'.

 Inside the black coloured plate, a revolving series of magnets rotates the pins at a high speed. This tumbling action keeps the little pins tumbling against each other.

 

  I have just one question: What kinds of jewellery can be cleaned in this machine? Here are just some of them:

 There is no way that a 'cloth, polishing wheel' can polish the intricate areas of these delicate bracelet links.

 Be forewarned that all of these sections of this bracelet should be tumbled before any total assembly.

 This top section of the clasp for this bracelet MUST BE CLEANED & PRE-POLISHED before any stone setting. 

 This way, all of the holes will be cleaned and be ready for setting.

  This large 14 karat gold ring MUST BE TUMBLED before any diamond setting is to start.

  This photo displays the 'before & after' pre-polishing techniques.

 Even before any of the square stones are set, the Magnetic Tumbler must do what is necessary.

 It is best to pre-polish the complete plate 'front and back' before engraving.

 

There is no possible method for cleaning this wedding band if not by Magnetic Tumbling. The cloth wheel cleaning process WILL DESTROY THE CLAWS IN MOMENTS.

  

 Even on this intricate engagement ring, 'Pre-Polishing' is essential and 100% required.

"You are only limited by your imagination!"

I dropped a small diamond, how do I pick it up?

"Darn, I dropped a .01 point diamond into my bench. I see it, but how do I get it out?

               =============================

 I've heard this question many times, and the answers cease to amaze me. First of all, don't use a pair of tweezers, as this won't grab such small gemstones as shown below. SQUEEZING THE STONE IS NOT TO BE DONE.

 The only recourse is to buy a 'wax pick up FOB'. The basic price is under $10.00 CDN, but well worth the purchase. You can pinch the tip with your fingers to make it into a finer point for smaller stones.

  In my earlier (1965) days, I used to melt 'finely mixed pieces of charcoal powder with hot candle wax' and mix this combination in my hand. This was an awful and dirty experience, but it got made.

 The whole purpose was not to leave any residue on the stones. These days, we can buy this new wax fob that will last for many months or even years.

 These three stones each measure .02 mm. I have smaller stones to show you...ready?

 The three larger stones measure 2mm; the group of really small stones are only .0122 mm in diameter.

 Here are the mini-sized stones that only a wax fob can 'safely' grip.

 Don't contemplate using any callipers to grab these little stones.

 If your fingers tremble, please use a wax fob instead (PLEASE.)

  REMEMBER THAT THIS $10.00 PURCHASE IN BUYING THE 'WAX FOB' IS THE GREATEST INVESTMENT THAT YOU CAN MAKE FOR YOUR 'ACTIVE BENCH'.

What is the least expensive method to polish gravers? => 16 photos

 I'm going to display the most expensive graver polishing machine on the market. I have just no idea why new setters might spend vast amounts of precious money on a machine that costs $2,575.00 (plus shipping & taxes).

 My polishing papers with the wooden sticks cost me EACH an estimated $30.00.

           ==============================================

This rotating disk machine comes with a price of $1,050.00.

==================================

This plastic, 'paper-holding board' is a mere $27.95

=================================

This rotating wheel machine has a price tag of only $1,585.00

==========================================

 This rotating table comes with a series of disks and other accessories with a price tag of only $2,575.00.

=====================================

 Why would I rub a soft-core drafting pencil into a polishing paper? The main reason is to increase the grit of the paper. It will make the paper of your choice from a grit of #800 to at least #1,100.

 This 'rubbing' will prevent any continual changing of papers. The pencil core will find its way into the pores of the paper.

 The following photos display the different (grit) textures of polishing papers.

  I went to a local hardware store and asked for 'paint stirrer' sticks. These sticks come in lengths of 11.5inches, which is great for the paper polishing sheets. 

 Instead of spending huge amounts of money, each of these gravers was polished on the 'wooden paint sticks'. I needed to maintain an oval shape to the sides of each graver. A flat metal disk will remove that angle.

 This collection of polishing sticks has been serving me well for the past 45 years. One of these sticks was from the year 1977.

 I like the softness of the 'paper on wood', as I won't have any problems with the sensitive 'graver on wooden sticks'. 

 This is a sample of the cost-efficient 'paint stirrer sticks' instead of the expensive rotating metal disk machines shown above.

 

"Show me designs for 'engagement rings & heads'" => 7 photos

 Here is a library of engagement ring 'claw settings' that are seen daily. As you can see, only a few of them have soldering pegs. 

(I will keep my preferences to myself as I need to stay neutral at all times.)

 These heads are designed for: 1)security, 2)ease of stone setting, and finally 3) appearance. It is quite common to have the jeweller pre-polish the 'head' before soldering it to the main ring.

All of the necessary 'karat and trademarks' must be stamped long before any of the gemstones are set.

  Here is an engagement ring set with many square "Princess-Cut"

diamonds, it also contains bead-set gemstones throughout.

 This 'Full Bezel' protects the Girdle of the stone throughout many years of wear.

 This Full-Bezel arrangement protects the delicate diamonds.

These are the best groupings of diamond ring heads that I've seen.

Safety in this engagement ring rates high in the 'flat-top' design.

 For a simple-looking Marquise ring, here is a two-toned combination.

Why do gravers come in different shapes? 9 photos

 We all use gravers for metal carving and gemstone setting, agree? But what shapes do they come in?

 All gravers come in equal lengths, but the only difference is how they are used.

==================================

These displayed shapes are used primarily in 'Diamond Setting'.

========================

These are the most common sizes for gemstone settings.

1) Flat gravers start in #37 (narrow) and finish at #42 width.

      2) Onglette graver shapes are #2/0, #1 and finally #3.

     3) Half-round blades are usually #51 & #52.

 I use a "Liner" (Florentine metal cutting blade). I generally use a #10/6. What are these numbers? 10 is the width, as 6 is used with the number of lines cut along the base of the blade.

Here are 6 metal cutting patterns done with gravers.

(These have just been shown in recent essays; now I'll explain which gravers were used in the cutting.)

-------------------------------

1) Here is the "Liner" or "Florentine" graver.

  2) 'Kite' or Onglette #0 did the outline cutting.

  
The circle cutting against the Flush Setting was accomplished by using a "Right-sided and shaped" Onglette graver using a #2 blade.

  I didn't use any Flat blade, but only an Onglette tool.

 

 This design was achieved by using two Onglette blades #1 and #3 engraving blade.

 Would you believe that only an Onglette blade did the actual metal cutting and metal shaping? For the rippling edging effect, I used only a Milgrain #2 tool.

 In this final photo, this pattern gave me only one chance to achieve the desired pattern.

 It isn't the graver, but how each one of them can be used. Not to mention the long-term skill of over 65 years at the bench.
