Product Description
This square shaped Old Mine Cushion Cut five stone halo engagement ring is made for someone who desires a vintage style with modern crafting techniques. The Ring is designed with a 1.70 CT square old mine cushion cut lab grown diamond, which has soft corners, wide facets, and has the same antique-like romantic glow as an old mine diamond. It is also true that the Old Mine Cushion cut stone uses more depth and warmth in addition to sharp sparkle compared to the modern Brilliant Cut. This is part of the reason that so many people select this type of ring for heirloom like engagements. In addition to the main diamond, this style includes two slightly smaller matching sections of cushion cut diamonds on each side of the main stone. The 5 stone layout lends to the overall appearance of balance and luxury. The overall design will provide a balanced appearance for the wearer; however, the large nature of this style will not feel bulky on the finger.
Each of the three main diamonds is surrounded by pave set halo diamonds. The halo design has the heart of the original Circlet design, yet the added effect of the halo diamonds and the use of the Old European Cut and Round Brilliant Cut (EF-VS) combine the old and new into one beautiful piece of jewelry. This design helps resolve one of the primary concerns customers have when deciding whether or not to purchase a halo ring. Yes, a halo will make the diamond appear larger, and in this style, the halo also serves to protect the edges of the cushion set stones. The ring is made of white metal, either platinum or white gold; the diamond fire is highlighted with long-lasting durability to stand up well to the rigors of everyday life.
The open gallery design of this ring's side allows for light to pass underneath the stone, enhancing sparkle and creating a comfortable and breathable ring. The micro pave shank runs the length of the ring, giving it maximum brilliance while still looking sleek due to its 1.90 mm width and 1.70 mm depth. The ring is made with lab grown diamonds (also called lab created, engineered, CVD, or HPHT), so the wearer can feel confident they have a beautiful item made without conflict or negative environmental impact. Customization options are available along with IGI certification for those over 1.00 CT and the timeless symbolism of five stones, making this ring an ideal choice for engagements, anniversaries, milestone gifts, or a significant luxury self-gift.

Five Stone Heritage Layout: Symbolic trilogy plus design representing past, present, future, stability, and lasting commitment in engagement jewelry.
