The elongated oval center sits inside an open basket that allows light to reach the diamond from below while the four-prong setting keeps the outline clean and balanced. Signora Jewels builds each ring to order, so every version is crafted specifically for your selected diamond size and metal.
The split cathedral shoulders rise toward the halo before flowing into the basket, creating support beneath the center while keeping the profile open. Fifty-six round accent diamonds frame the center and continue across both shoulders, giving the ring sparkle from every viewing angle.

About Lab Grown Diamonds
The oval brilliant cut combines long, elegant proportions with broad flashes of light across the crown. The surrounding halo increases the visual size of the center stone while preserving the graceful outline of the oval shape.
Metal, Care & Fit
Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean the halo and pavé diamonds regularly with warm water, mild soap and a soft brush to keep the small accent stones bright. The open basket also makes cleaning beneath the center diamond easier.
FAQ
Does the halo make the oval center appear larger?
Yes. The halo surrounds the oval with closely matched round diamonds, increasing the overall face-up appearance without changing the elegant proportions.
Why is the split cathedral shank used on this design?
The split cathedral shoulders support the center setting from beneath while keeping the gallery open and balanced.
Can I choose a larger center diamond?
Yes. This design is available with multiple center diamond sizes from 1 ct through 4.5 ct while maintaining the same overall style.
Which metal color best complements the blue center diamond?
White Gold and Platinum emphasize the cool blue tone, while Yellow and Rose Gold create stronger contrast that makes the center diamond stand out.
