The “Kilauea” Classic Ruby Ring



Simple. Classic. This ring is made-to-order, but unlike most of our rings, the center gem is included in the price. Typical delivery time is 4-6 weeks.

SKU: WR-SOL-115 Categories: , , ,


The “Kilauea” classic sapphire ring is a smooth, powerful statement with a passionate deep red ruby. This style features an inset 6 x 3 mm ruby and a band that tapers from 7.5 to 4.5mm as well as a flat, standard fit interior profile. You have the option of a high polished, hammered, or brushed satin finish. The rubies in this ring are sourced from Mozambique and presumed subject to low-temperature heat treatment, as this treatment is common in ruby and difficult to detect (and at this size, not worth the cost of a lab test to verify). The treatment is permanent and stable and not only develops the color, but also improves the clarity. Each ruby may vary slightly but weighs 0.44 carats on average.

This ring can be created in US sizes 5.0-13.0 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, 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. If you have any questions or special requests, please contact us.
