Engagement Rings

Diamond color is graded on a D–Z scale, with D-F being colorless and most prized for brilliance and sparkle. At Joslin’s, only top-quality diamonds, typically D–H, are selected to ensure maximum radiance and versatility in any setting. Expert staff help customers balance color with the other 4Cs and the chosen jewelry, ensuring a beautiful diamond without overspending. Subtle differences between top color grades are often only visible under magnification, allowing Joslin’s to guide clients toward the best value without compromising appearance.

A diamond’s cut refers to how its facets interact with light, creating brilliance, fire, and sparkle. Unlike color or clarity, cut is entirely man-made, carefully designed to maximize light reflection and refraction. Grades range from Excellent to Poor, with a well-cut diamond appearing radiant regardless of its other qualities. At Joslin’s, expert guidance ensures each diamond’s cut enhances its beauty, so even top-color or clarity stones shine to their fullest potential.

Clarity measures a diamond’s purity by assessing internal inclusions and external blemishes. While flawless diamonds are extremely rare, most stones in the upper clarity grades (IF, VVS, VS) appear eye-clean, with no visible imperfections. The size, type, number, and location of inclusions all affect a diamond’s appearance and sparkle. At Joslin’s, experts guide customers in selecting diamonds and settings that minimize visible flaws, ensuring maximum brilliance while balancing quality and value.

Carat measures a diamond’s weight, not its apparent size, and is a major factor in price, but it should never be considered in isolation. Two diamonds of the same carat can look very different depending on cut, proportions, and other factors. At Joslin’s, experts help customers balance carat with color, cut, and clarity, ensuring each diamond delivers maximum brilliance, beauty, and value for their budget.
