Our Materials

Below is a listing of the materials I use to make jewelry that is as unique as you are.


I use a wide variety of semi-precious and some precious gemstones in the creation of my jewelry designs, including pearl, turquoise, onyx, smoky quartz, peridot, labradorite, paua shell, amethyst, ruby, and sapphire among others.

Natural pearls and gemstones vary in size, shape, and color, therefore the pearls or gemstones in your pieces of jewelry will be very similar to the ones in the images, but may not be identical. These variations are the result of time, sometimes eons, and the work of skilled gem cutters and only add to the beauty and individuality of your handcrafted pieces of jewelry.


Cultured Freshwater Pearls
Cultured freshwater pearls come in many shapes, sizes, and colors. Pearls occur naturally in the colors of white, cream, pink, peach, mauve, and some grays. The art of dyeing pearls has been perfected in Japan, and produces beautiful and colorfast green, purple, gold, and brown pearls.

Swarovski Crystal Pearls
Swarovski Crystal Pearls are coated with real nacre – the same substance found in natural pearls – so they have the weight, luster, and feel of real pearls. This makes it possible to enjoy large, perfect pearls at a fraction of the cost. Swarovski pearls change to reflect the temperature of the wearer’s skin, much like natural pearls do.

Unlike lesser quality imitation pearls, the finish on Swarovski pearls is not susceptible to damage caused by perfumes, lotion, or perspiration and are resistant to scratches.

Shell Pearls
Shell Pearls are also a good source for large and lustrous pearls. Shell Pearls are made from large oyster shells found off the coast of Vietnam which are cut into shapes, polished, dyed, baked at a high temperature, and polished again to produce pearls of beautiful luster and color.


In addition to Swarovski crystal, I favor the soft brilliance of Czech fire polished crystal for some designs and quality Chinese crystal for others.

Gold Filled

Most of the gold jewelry in my collection is created using 14 karat gold filled wire and will be designated as such. Gold filled metal is a high quality and economical alternative to 14 karat gold and gives the “look and feel” of 14 karat gold at a fraction of the price. It consists of a thick outer coating, 5% of its weight, of 14 karat gold bonded to a brass core. All but the most sensitive are able to wear it comfortably. The bonded outer layer of 14 karat gold of goldfill is many times thicker than gold plate or vermeil. It is also more durable than 14 karat gold of the same thickness and will give years of wear and enjoyment. Avoiding contact with hairspray and cologne will help protect its luster. It can be polished using a soft, clean cloth, as needed.

14 karat gold ear wires can be made available upon request

Sterling Silver

K. Boulet Designs uses tarnish resistant Sterling silver in the majority of its silver jewelry creations.

Silver Filled

An economical alternative to sterling, silver filled wire has a very heavy outer coating of sterling silver, comprising 10% of its weight. It is a quality and long lasting material that like sterling can be polished with a soft cloth and non-abrasive cleaner.
