The “Moirae” can be crafted with most shapes of our gemstones. Your ring will be custom-designed to fit your exact gem. This style features a three-stone look with an included round and pear-shaped diamond. The 2.5mm wide band tapers to 1.5mm at the top. This style includes a 5.0 x 3.0 mm pear-shape diamond and a 3.0 mm round diamond with G+ color and VS clarity, weighing an approximate total of 0.30 carats. A center stone with a length around 7.0mm is recommended to maintain the same proportions as the pictured examples. The size or quality of the diamonds can be customized upon request, and may incur additional fees. The pictured example shows an upgraded version with larger fancy-color and heirloom diamonds against a 2.22-carat sapphire. This style is pictured with claw prongs but other prong styles are available upon request.

This ring can be created in US sizes 3.0-10.5 including quarter sizes. Further sizes are available upon request but may incur an additional charge. The ring can be created in 14k or 18k yellow or white gold, 14k rose or 20k pink gold as well as platinum. To order, first find your perfect gemstone from our extensive inventory and add it to your cart. Then select your preferred ring size and metal type before adding this ring to your cart and checking out. The typical turnaround time is 4-6 weeks from the date of your order.

All rings are delivered in a custom wooden gift box and a lifetime warranty against any manufacturing defect. Made-to-order jewelry is not returnable; please see our returns policy for more details. A matching wedding band can be ordered separately; this style pairs best with a curved or contour band. If you have any questions or special requests, please contact us.
