Our Diamond Selection Process

Though we believe every piece of jewelry is an investment, worthy of care and safekeeping, there is something special about diamonds. Diamonds are the international gemstone of choice for marking significant events. We propose with diamond engagement rings. We exchange vows while slipping a diamond-studded gold band onto our love’s finger. Diamond necklaces or earrings are often gifted to new mothers.

Diamonds have become symbols of love and commitment.

Because of this, we also believe in using diamonds that are free of conflict and violence to fellow humans and the planet. Our diamonds are ethically mined. They are conflict-free. And each of our diamond solitaires is inspected by a trained gemologist to ensure the stone is “eye-clean”—flawless to the naked eye.

We are honored that our customers trust us to handpick the centerpiece diamonds for their bespoke engagement and wedding rings. Today we'd like to share a bit of that process with you. The following is a peek into our step-by-step search for your perfect stone:

  • First, we believe in using your budget toward what you can see with your naked eye. “Eye-clean” is our goal, every time. While an inclusion (an internal flaw) on the side of a stone might give it a lower overall diamond rating, it might still be a perfect diamond depending on your ring setting. It’s possible the inclusion will remain hidden forever. But that same inclusion on the top facet (the table) of your diamond? A different story.
  • Second, we consider the cut of the diamond. We offer a variety of cuts: round, pear, princess, emerald, cushion, and more. Regardless of the shape, a great cut will improve your diamond’s appearance. In fact, the cut can effectively raise the diamond’s grade one or two steps higher than its certificate. A well-cut H diamond will look more like an F or G (most engagement rings range from D-K). Beautifully cut diamonds hide defects amongst the sparkles and flashes of fire.
  • Third, we look beyond the 4Cs. There are four specific characteristics we assess other than cut, clarity, color, and carat. We look for the following:
  • Fluorescence. Diamonds often emit a soft, colorful glow under UV light (black light). Nearly a third of diamonds contain this glow, called fluorescence, which can range from negligible to a strong blue flare. Fluorescence is considered a defect in diamonds. But because this so-called flaw is only visible under ultraviolet light, we can often obtain a beautiful, quality diamond that costs less without compromising beauty.
  • Fire. A diamond’s fire refers to the colorful sparkles the stone emits under light. There is something delightfully lively and brilliant about a diamond full of fire. Cut determines a diamond’s fire—a well-cut diamond will bend and reflect light to maximum effect.
  • Brilliance. In contrast to fire, brilliance refers to the colorless light a diamond emits. Beautiful diamond refractions often include both fire and brilliance. When a quality stone is seen in the light, it will seem to explode with brilliance and fire.
  • Scintillation. If you have ever watched someone wearing a diamond ring shift her hand under the light to create a spray of rainbow refractions, you have seen scintillation. These are the brilliant flashes of light we see when a diamond is in motion. Scintillation is also key to hiding tiny inclusions (internal flaws) in a well-cut diamond.

Our skilled gemologists consider these factors and more when selecting your diamonds. To give you more dazzle for your dollars, we consider physical dimensions as well as carat weight. We prioritize cut above all else. And we honor your budget because we understand that purchasing an engagement ring can be a daunting process.

There is so much meaning and sentimentality in a handcrafted, bespoke piece, and we would love to be a part of your journey. Get in touch at hello@lucyandmui.com.
