Specifications

Options and pricing

Ready to ship, the ring is platinum with the 5.02ct stone. Made to order, the listing offers 9K, 14K or 18K solid gold or platinum and an oval cut lab diamond from 1ct to 10ct. It shows one price, $1,899, without prices for the made to order metals or stone sizes, and no ring sizes are given. The store shows a crossed-out higher price of $2,999, which is the store's own comparison and not a market price.

How it compares

The 3ct Oval Cut Halo Pave Engagement Ring in Platinum also lists platinum ready to ship and an oval cut stone, 3.1ct at $1,878.90 in a Halo Pave setting, against 5.02ct at $1,899 in a Cathedral setting here. The 5ct Radiant Diamond Hidden Halo Pave Engagement Ring in 18K White Gold lists $1,935.20 for a 5.01ct radiant cut stone in 18K white gold.

Shipping, returns and warranty

Shipping is free worldwide on most orders: ready-to-ship items are dispatched in 1 to 3 business days and orders of $500 or more travel by DHL, FedEx, UPS or USPS in 3 to 7 business days. The FAQ gives 8 to 12 business days of dispatch plus 5 to 15 calendar days instead, so allow for the longer figure. Duties and taxes are included for most destinations. Returns: 30 days from delivery for a refund of the product value and standard shipping, with the buyer paying return shipping unless the item is wrong or defective; custom orders, special orders, engraved items and altered loose diamonds are final sale, and an order can be cancelled only within three hours. Warranty: a free lifetime warranty, a one-time free replacement of a diamond up to 0.10 ct on first loss, and a promise to replace a diamond if the same grading laboratory later grades it lower. Checkout runs through PayPal, which also takes cards.

Before you buy

Rose Majester is a young store: its domain was registered in March 2025, and the company says it was founded in 2023 in Changsha, China, with a showroom in Macau. Searches on 19 October 2026 found no buyer reviews on Trustpilot, BBB or Reddit, so its claims have no outside check. Every listing we read shows a crossed-out higher price, and the store's "up to 76% lower than traditional retail" line is its own claim, not a market price. Its pages also disagree: delivery times differ between the shipping page and the FAQ, and the FAQ says every diamond piece over $500 comes with an IGI jewelry report while some listings call the report optional. Ask the store, for example on WhatsApp, to confirm the report, size and resizing before you pay, and keep the PayPal receipt.
