I know which store to recommend))
If you are looking for a really high-quality ring, handmade, as for a bride, then it can be yourasteriajewellery. I’ve been ordering from them for a long time, the website has very affordable prices, most of them with discounts, and the quality is the best, because the brand owners are very responsible for production. By the way, they have their own production, so the store itself is responsible for the terms of production, quality, materials, etc.
The last time I ordered an oval ring with a sapphire from them, but for autumn it is really better to choose yellow shades like citrine https://yourasteria.com/collections/citrine-rings
