Center Stone Selection

Selecting a diamond and getting a great value is no easy task. Every diamond that goes through Knox Jewelers is personally inspected and graded by Brent Knox, son of the owner Brian Knox. He is an expert at finding the best quality and the right value in diamonds. He'll work directly with you and your designer, focusing on the quality you want and the budget you set. His name does happen to be on every ring we make.

Finding the right diamond isn't about the 4 C's. It's about the correct diameter to weight, good or bad clarity grades, bright and lively cuts, the perfect depth percentage, and the best weight to value. Sometimes fluorescence hurts a stone, other times it helps. We know everything there is to know about finding the best diamonds and it's in our best interest to ensure you are completely satisfied with yours.

Finger Sizing for Custom Engagement Rings

Custom Engagement Ring Finger Sizing

Whenever possible, we'd like to measure the finger that the custom engagement ring will be worn on. Since we are making this fine piece of jewelry specifically for that special someone, we should try and make it as close as possible to their finger size. We are able to send out plastic sizing devices that are calibrated to our shops mandrels. As all master jewelers should, we are able to make our rings to the 1/8 size.

Don't panic if you don't know her size and you want to keep this a surprise. Our ring sizing page has a printable guide to help you make an estimate if you can measure one of her existing rings. If that won't work, we are very good at estimating her size based on her height, weight, and body type.

Don't worry if the size is off as we offer a free resizing within the first 12 months. It's completely seamless and won't affect the integrity of your custom designed heirloom.

Best Metal Type for a Custom Engagement Ring

Selecting the Right Metal for Your Heirloom

Knox Jewelers custom engagement rings and wedding bands are available in the following metals:

  • 950 Platinum Ruthenium
  • 14k & 18k White Gold
  • 14k & 18k Yellow Gold
  • 14k Rose Gold

Please note that the majority of pricing on our website is for 14k White Gold, our standard alloy. If your budget allows for it, we wholeheartedly recommend Platinum for engagement rings that are worn everyday. Read more about Platinum vs White Gold here.

We strictly adhere to environmentally friendly processes and strive to make our world a better place to live. Knox Jewelers uses 100% recycled Gold and Platinum in the manufacturing of all our fine jewelry. The mining of precious metals has devastating effects on the land and environment. Waste products and chemicals used in the processes contaminate ground water and render soil useless. Our recycled metal is a more sustainable approach to a healthy and clean environment.
