Designthis

Custom designs or bespoke designs are designs that are made to order, per the customer’s specifications. When you use our Designthis service, you specify exactly how the design should look (either by providing a photo, drawing, or description) and our designers use that information to create a 3D file. Once completed, the 3D file is ready to be 3D printed, cast, and produced. You will then have the option to download the design and produce it yourself or use our Producethis service and have us do the work for you.

Please provide the following information when starting your Designthis project/order:

  1. A photo/sketch with a 3-sided view of the jewelry design you would like created.
  2. The type of jewelry piece you want to create (ring, earrings, bracelet etc.).
  3. Answers to the online questions we ask you about your jewelry design when you request your quote. (These questions are designed to reduce errors, time and the cost of producing your designs).
  4. If your design will include stones, you should provide all the information about the center and side stones that you want your design to include. If you are not sure about the dimensions, setting, or count, you have the option to approximate or leave the decision to the designer’s discretion.
  5. Ring size and the type of shank wanted if your design is for a ring. (See our ring size FAQ for help with determining ring size).
  6. Bracelet or bangle size if your design is for a bracelet or bangle. (For help determining bangle or bracelet size, see our FAQ on bangles and bracelets).
  7. Any special instructions, other information or details that will help the designer build the model.

Yes. Just look for the “Customize” tab on the product design page. Designs with this tab can be modified.

 

Modification fees

In general, as part of each Designthis project, we let the client view the project and if needed, ask for one FREE refinement. We provide this courtesy because we understand that the client might want a minor adjustment made after viewing the model.

However, in cases where the client wants modifications made to the design, or more than one refinement, a modification fee will be applied.

The difference between a refinement and a modification

A refinement is a small improvement or change to the design that is based on the original project scope and description. This should not be confused with a modification of the design, such as adding, removing or changing the structural element of the piece, which requires many more hours of work.

Does this distinction also apply to an organic model?

Organic CAD jewelry is designed using special software that lets the designer capture the jewelry piece conceptually. Organic jewelry designs are more free-form than non-organic designs, which use mathematically precise representations and are easier to modify than organic designs.

For example, if modifications are required in a non-organic design, such as making a change to the size of the center stone, the modeler just has to change a number in the software and adjust the total size to make the modification. For general designs this process takes about a ½ hour maximum.

However, organic designs, have more limitations and are much more complicated to modify because of their free flowing form. If we are asked to merge two flower blossoms into one, for example, we need to remodel the entire piece. We cannot simply change a number to get the desired result.

Consequently, whenever possible, we send our clients a drawing prior to creating the design, in order to first get their feedback. Once the drawing is approved, we create the design. In situations where the client does request changes to an organic design, we can accomodate the request, but a modification fee will apply.

It’s also important to keep in mind, that when you review a model with our STL viewer, it is scaled up. This is like looking at the model with a magnifying glass; all the small details seen in this view (like the tip or the lines) will not be visible in the final production of the piece.

Yes. You can send us drawings, photos, and sketches. Of course, the more specific your drawings/photos are, the easier it is for our designer to see what you want. For helpful sketch and photo tips, please see our FAQ, “How exact does the sketch for a custom order request have to be?”.

Sketches of the jewelry model that you would like us to create for you do not have to be perfect. We will accept any sketch. You can even draw it on a piece of paper and take a photo of it with your phone and send it to us that way. The important thing is to provide us with a sketch of 3-4 sides of the model so that the modeler will understand exactly what you want and then know what to do.

Helpful tips:
1. We have created templates for each ring size to help you make your sketch, these are enlarged mm pages. You can download the relevant PDF from this page (click on the appropriate link in the US column) or download all files from this link.
2. When you sketch, start with the front view (center stone first), then follow with the top view and end with the side view.
3. When you scan/take a photo, place your phone so it is positioned above the page and not below it; this will prevent the photo from being distorted.

Here is an example of a sketch, so you can see what we need from you:

 

 

 

 

Milgrain (Mille Grain, French) is a jewelry design technique that has been around for thousands of years, but is still very popular and found in many contemporary jewelry designs. The term, which means ‘a thousand grains’ in French, refers to a technique whereby close-set, tiny indents or bumps, that look like little beads, are added to the borders of a design. It’s most commonly seen along the outer edges of wedding band rings. The Milgrain technique gives a piece of jewelry a sense of craftsmanship and even adds a little sparkle to the design.

Engraving, on the other hand, refers to the technique of cutting or carving grooves into the surface of a jewelry piece to create an image or pattern. The engraving can be anywhere from simple to elaborate. Engraving a jewelry piece can provide a more personal effect.

Both Milgrain and engraving can be shown in CAD jewelry designs, but there are a few limitations. With Milgrain, for example, some of the tiny bumps and indents can be lost. Thus, for the Milgrain technique, we recommend that it be done by hand. With engraving, the basic grooves are done in CAD, but the pattern needs to be added by hand after casting.

Delivery time depends on the complexity of your request. For non complex / organic pieces delivery time takes up to three business days. Furthermore, when you place an order, you can request a due date and our design team will let you know if they can meet that date.

For more information about the delivery and shipping, please see our FAQ on receiving orders and rush orders.

Prices are determined by the type of the design and its level of complexity, taking into consideration, the time and effort it will take the modeler to build the file based on the information provided. Remember: The more information provided. the more accurate the design will be and the lower the quote will be.



Before approving the design, you will be able to use our STL viewer to view and inspect your design. If refinements or improvements are needed, just request a revision and we will change the design per your request. Your first refinement is free and is included in your project cost. For instructions on using our STL viewer, please see our FAQ, “How do I use the STL viewer to give you feedback about a design?“.

Using our STL viewer to check your file before you approve the project or as a tool to provide the designer with your feedback. Click ‘‘view’, next to the STL icon. This will open the viewer and start loading the file. Once loaded, the viewer lets you maneuver the design, so it can be seen from different angles, and shows the design’s dimensions and volume. Note that each cube you see in the viewer represents a 1 mm square, which helps you get an idea of the scale.

Using the viewer as a measuring tool. Clicking on one point of the model and then right clicking again on a 2nd point will give you the distance between those two points. Although the measurement might not be 100% accurate, it will give you a good idea of the distance.

Using the viewer when providing feedback to the designer. When requesting a modification, you can ‘printscreen’ the viewer and include your comments on the photo.

  1. Start by positioning the model in a way that best shows the area you want to modify, then click on the ‘pencil’ icon. When you do this, a new window will pop up with the design.
  2. Use the editing tools on the left to write your comments, such as pointing with the arrow etc.
  3. When done, click on the ‘attachment’ icon.
  4. Repeat this step for each change you want made.
  5. When you have finished indicating the changes, close the viewer; each attachment you made will then be attached to the message board.
  6. Write further instructions or comments in the comment box. And don’t forget to click the ‘send’ button. This will send all of your comments and attachments to the designer.

We’ve published the table below, which you can use to help you determine the correct ring size when searching for and uploading models. Since ring sizes can vary from region to region, the metric system was used as a baseline for this table.

We have created templates for each ring size to help you make your sketch, these are enlarged mm pages. You can download the relevant PDF by clicking on the appropriate link in the US column or download all files from this link.

Don’t know your finger measurement?

Measuring your finger for ring size is easy. If you already have a ring that fits just right, just measure the space from one interior side to the other interior side (the diameter). This will give you your ring measurement.

If you don’t have that perfectly fitted ring, there’s an easy workaround for that too. You’ll need some paper, a pen or pencil, scissors and measuring tape (or a ruler). Here’s what you’ll need to do:

Cut a thin strip of paper (approx. ⅛” – ¼” wide) that can wrap around your finger one time. It should fit securely enough around your finger so that it’s not so loose that is might fall off, but not so tight to make it uncomfortable when worn.

Use your pen or pencil to draw a line where the paper ends on your finger. Then, lay the marked strip of paper out flat and measure the length of the paper from your mark to the end of the strip. That number is your ring measurement.

Now that you have your measurement, you can proceed to the next step by looking for your measurement in the table below to find your comparable ring size.

Adding a gem to a model can be tricky. We want to build the model around the stone so that it fits the model exactly and the setting is just perfect.

If we’re talking about a standard gem e.g a 5mm round or square diamond, it’s fairly simple for us to use a generic stone for the dimensions. However, for special stones we need to know the exact dimensions. Here are a few different options for “sending” those dimensions to us.

If you have a 3D / 2D scanner:

You can use a 3D scanner ( a Sarin works best for us) and send us a scan of the stone, which allows the modeler to see each stone perfectly, without distortion.

Another option, is to use a 2D scanner to send us a front and side scan of the stone, while placing a millimeter paper on the back.

If you don’t have a scanner:

If you have a stone or stones with unique dimensions and do not have access to a3D scanner, we will be happy to help you.

Ship them to us, we will scan them (which takes an average of 15 minutes per stone) and then save the 3D scans in your Jewelrythis account. We will then ship the stones back to you and will have the scanned and saved the stone information for whenever you want to order a custom design.

Please contact us before you ship the stones, and be sure to insure them prior to shipping.

If you don’t want to ship your stones and don’t have a scanner:

If you do not have a scanner, though, don’t worry, there is another option. You can download this easy-to-complete page, list all your gem information and then send it to us (you can take a photo and upload it to the project).

If you have a non-generic gem, please follow the instructions provided and send us the necessary information:

  1. Draw a top view of the stone: write the length, width and two diagonals (optional).
  2. Draw a side view of the stone – write the height.
  3. Take a photo of your sketch and upload it when you send us the project.

For clarification, a few examples have been provided below:

Taking a 3-sided photo will help us to “better see” the gem. Make sure to take the photo from the vertical point to reduce distortion.

A bangle is a solid, one piece band that is worn on the wrist and that does not have a clasp or opening,

Here are a few beautiful examples of bangles:

To determine the correct size for a bangle, measure the widest area of your hand so you’ll be able to easily slip the bangle off and on your hand.

Bracelets, on the other hand, do have a clasp so that they can be opened around the wrist and they are flexible. Bracelets can be either circular or elliptical.

Here are a few beautiful bracelet examples:

To determine bracelet size, measure your wrist size. For a looser fit, add a few mm/cm to the size.

How to Measure Size for Bangles & Bracelets

Important! When you print the document, make sure you specify actual size, in the print instructions so that the measuring tools print out accurately.

 

Don’t have a printer? No worries. Here’s what you do:

If you already have a bracelet that fits just right, just measure the space from one interior side to the other interior side (the diameter). This will give you your measurement.

If you don’t have that perfectly fitted bracelet, there’s an easy workaround for that too. You’ll need some paper, a pen or pencil, scissors and measuring tape (or a ruler). Here’s what you’ll need to do:

Cut a thin strip of paper (approx. ⅛” – ¼” wide) that can wrap around your wrist one time. It should fit securely enough around your wrist so that it’s not so loose that is might fall off, but not so tight to make it uncomfortable when worn.

Use your pen or pencil to draw a line where the paper ends on your wrist. Then, lay the marked strip of paper out flat and measure the length of the paper from your mark to the end of the strip. That number is your wrist measurement.

For bangles, the process is the same, but you will measure the width of your hand from its widest points. Touch your little finger to your thumb and then use the strip of paper to measure the circumference of your hand around the widest points.

 

 

Comfort-fit shanks use more metal than standard or regular-fit shanks in order to make the interior of the ring more dome shaped, which results in a more comfortable fit. In contrast, standard or regular-fit rings, have a straight interior and do not have the extra dome of metal that is characteristic of comfort-fit bands. Typically, men prefer comfort-fit rings because they are easier to squeeze over the knuckle when taking the ring off or on as well as significantly more comfortable to wear once they are on the finger. Because comfort-fit bands are crafted from a thicker band, they are usually more expensive than standard-fit bands.
