Buying guide
A princess cut is a square brilliant cut with pointed corners and strong sparkle. In a 3 stone princess cut engagement ring, the square center sits between two smaller stones, which gives the ring a wide, balanced look. The geometric outline feels clean and modern, and it pairs well with straight wedding bands.
The corners of a princess cut are its thinnest points. Prongs over each corner hold and protect them, but it is still sensible to take the ring off for heavy work or the gym. A soft brush with warm soapy water keeps all three stones bright.
White gold and platinum suit the sharp, icy look of a princess cut; yellow and rose gold soften it. Gold is offered in 10K, 14K or 18K. Platinum is the densest and most durable metal and costs more. The band comes in widths from about 1.8 to 2.2 mm. Prices start from about $1,150 with the 1 carat center included.
Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
