Frequently Asked Questions (FAQ)
Q1: What is the best way to set a trilliant cut diamond as a center stone?
Because trilliant diamonds have three distinct points, protecting those corners from chipping is crucial. We highly recommend using V-prong settings or bezel settings that wrap around the points. This not only secures the stone safely for everyday wear but also enhances its sleek, geometric aesthetic.
Q2: Why choose laser-drilled trilliant diamonds for manufacturing?
Laser drilling is a clarity enhancement treatment that targets dark inclusions to make them less visible. For jewelry factories and custom studios, this means you can purchase stones with excellent visual appeal at a lower price point. Furthermore, the treated inclusions often provide subtle visual markers that can actually help jewelers align and set the stones more accurately during the manufacturing process.
Q3: Can trilliant diamonds be used as side stones for non-triangular center stones?
Yes, absolutely. While they are often paired with other trilliants, their tapered shape makes them excellent side stones for round, oval, or cushion-cut center stones. They create a beautiful, modern contrast, framing the softer curves of the center diamond with sharp, architectural lines.
Q4: How does the brilliance of a trilliant compare to a round brilliant?
While a round brilliant is engineered for maximum light return, a trilliant cut also features a brilliant-style facet pattern. This means it still offers exceptional sparkle and fire, but the light is dispersed in a more dramatic, geometric way. The result is a bold, icy-white flash that catches the eye differently than a traditional round cut.
Q5: Are trilliant lab-grown diamonds a good investment for bridal stock?
They are an excellent addition to a bridal inventory. As more couples seek unique, non-traditional engagement rings, the trilliant cut satisfies the demand for distinctive, personalized jewelry. Because lab-grown trilliants offer significant cost advantages over natural fancy shapes, jewelers can offer highly unique, custom-looking rings at accessible price points, driving higher margins and customer satisfaction.
