A marquise lab grown diamond cathedral engagement ring from Signora Jewels.
An 11.66 × 5.71 mm marquise centre of approx. 1.70 ct, set in six prongs, with 2 marquise accents and 4 round accents totalling approx. 0.12 ct. Approx. 1.82 ct total.
Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.
Signora Jewels builds this ring around a long marquise centre, then keeps the detail in the shoulders. On each side, an open frame holds one small marquise diamond and two round diamonds, so the ring reads first as a centre-stone design, not a full three-stone layout.
The centre sits about 4.50 mm high in a six-prong head. The shoulders taper into a 1.70 mm base, while the top width reaches about 2.20 mm. It stays light on the hand, and the open side sections let more of the accent work show when the ring turns in the light. See more engagement rings and compare finishes in our metal guide.
Design highlights
- Marquise centre diamond, approx. 1.70 ct in the photographed ring
- Customizable centre size from 1 ct to 4.5 ct
- Six-prong cathedral head with protected pointed ends
- 2 marquise shoulder accents totalling approx. 0.06 ct
- 4 round shoulder accents totalling approx. 0.06 ct
- Open shoulder frames and a polished 1.70 mm base
The shoulder layout is what makes this design. Instead of pushing large side stones right up against the centre, it leaves a little air around the head, then places the accents farther out in open frames. That keeps the marquise centre long and clean from the top view.

About Lab Grown Diamonds
A marquise cut gives more visible length than a round of similar weight, which is why it works so well in a narrow cathedral head. The accent mix here matters too: the small marquise stones echo the centre shape, while the round accents break up the line and add extra flashes along the shoulders.
Metal, Care & Fit
White metals keep the whole top view bright, while yellow and rose gold put more contrast around the diamonds. Clean the ring with warm water, mild soap and a soft brush, working underneath the head and through the open shoulder frames. For routine upkeep, use our jewelry care guide.
FAQ
Are the pointed ends of the marquise centre protected?
The centre is held in six prongs, including end prongs at both tips. That gives the points better coverage than a four-prong head and helps on day-to-day wear.
Is this ring a three-stone design?
No. The centre is the only main stone. The two small marquise diamonds and four round diamonds sit in the shoulders as accents, so the ring wears more like a cathedral centre-stone ring with side detail.
Will a straight wedding band sit flush next to it?
A straight band will usually leave a small gap. The cathedral head and open shoulder structure take up space beside the centre, so a curved or contoured band sits closer.
Which metal colour suits this design best?
White gold and platinum make the diamond layout read as one bright surface from the top. Yellow and rose gold show more contrast around the shoulder frames and make the structure easier to see.
How do I clean the accent stones in the shoulders?
The open side frames make this ring easier to clean than a closed gallery. Use a soft brush from the side and underneath to reach the two marquise accents and the four round diamonds.
