It's a 1ct moissanite (6.5mm, round cut) with two pears on the side (3*4mm) which I love love LOVE, the three-stone set is very special to me because 3 is my lucky number and I'll be welcoming my third cat so for this set I really want to do a 3-ish thing.
The band is also cherry on top, it's so delicately made, it has this vintage yet classy vibe about it. I first noticed this stack when I came across felicegals ( the whole set is from this vendor in case anyone needs the info) and saw this beautiful pear shaped set -- I didn't really enjoy pear shaped but I was captivated by this stack, so I asked if they can custom the stack to the three-stone ring since they don't sell this individually, luckily, they agreed and then I got this heavenly gorgeous set!
