Recently, a customer contacted me on Etsy who wanted a custom design. He wanted a platinum Mother-Child Knot Necklace. His wife inherited a diamond ring. He wanted to take the diamond from the old ring and mount it into a pendant. He saw my version of the Mother-Child Knot Necklace with birthstones on Etsy, and wanted a version of it with the diamond in the center.
The Design of the Platinum Mother-Child Knot
Up to now, I had not designed anything with prongs. I wanted to be cautious about this because he also wanted the pendant made from platinum. Therefore, the pendant would cost quite a bit. Because of the expense, there was no room for error.
First, I had to figure out how to design the prongs. The customer got me the basic dimensions of the diamond. I took that information and created a rough 3D model of the diamond. Then I got a tip from a fellow designer on Shapeways. He recommended I check out a web site called Wizegem. From that, I got a prong model from that was very close to the correct size. I then downloaded it and brought it into Blender, and scaled it a little bit to make it the exact size I needed.
At that point, I shared screenshots of the first attempt with the customer to see if it looked like what he had hoped. He requested a couple minor changes. Once those were done, we ordered a plastic version of the pendant and it was sent it to him. He verified that the diamond fit in the prongs perfectly. Finally, we placed the order for the platinum version.
The Finished Product
The version in the picture attached to this post does not have the actual diamond. It has a Swarovski crystal, which is a bit smaller than the real diamond will be. I placed it there just to give an idea of what it will look like when it is all done.
I am in the process of learning how to add gems and other stones to my jewelry designs. It’s something I had wanted to learn how to do for a long time. I’ve finally learned enough about gems that it was time to give it a shot. One of our first offerings will be two versions of a birthstone pendant.
The birthstones we are using are Swarovski crystals. These are synthetic versions of the gems. The only exception is the stone we are using for June. For that one we have Moonstone instead of crystal.
The crystals and stones in these two designs are 3.0mm to 3.2mm in diameter. We placed them inside the negative space of the Celtic knots. The Motherhood Knot can be bought with up to six birthstones. So far I have only created a version of it with one birthstone and three birthstones as test runs. There are other spots identified for all of the variations. The Mother and Child Knot is simpler. It only has two birthstones, one representing the mother and one representing the child.
See the table below for all of the birthstone choices and the meaning behind each one.
Aquamarine (light blue)
Strength and courage
Pearl or Moonstone (white)
Love or Fertility
Ruby (dark red or maroon)
Harmony, or protection
Peridot (light green)
Purity of spirit
Sapphire (dark blue)
Opal or Tourmaline (pink)
Topaz or Citrine (gold)
Turqoise (light blue)
We have more designs in process that incorporate gems and stones. Please stay tuned for updates as we continue to expand our offerings.
