Our verdict

A reasonable choice for someone who wants a plain cathedral solitaire with a 5.08ct round cut lab diamond (E, VS1), ready to ship in 18K white gold at $2,259. Look elsewhere if you need a band width or total carat weight, or a price for a made-to-order stone, because the listing gives none of them. The main caveat is the short spec sheet.

Someone who wants a round solitaire in a cathedral setting, ready to ship in 18K white gold.

You need band width, total carat weight or a stated price for the made-to-order stones.

Why 3.6/5: The IGI certificate named on the listing and the ready-to-ship stock raise the rating, while a sparse spec sheet and no independent buyer reviews hold it down.

A 5.08ct round cut lab diamond graded E for color and VS1 for clarity sits at the center of this cathedral solitaire, which the store lists in ready-to-ship 18K white gold for $2,259. The title calls the stone a round brilliant. Behind that single ready-to-ship ring the listing sets out a made-to-order range, with round stones from 1ct to 10ct and a choice of gold karats or platinum.

Options and pricing

Ready to ship: 18K white gold with the 5.08ct stone. Made to order: 9K, 14K or 18K solid gold or platinum, with a round cut lab diamond anywhere from 1ct to 10ct. The listing does not name gold colors for the made-to-order version, gives no ring size list, and does not say how the $2,259 price changes with a larger or smaller stone. A crossed-out $3,499 is shown by the store as a higher comparison price; it is the store's own figure and not a market price.

How it compares

Two nearby rings from the same store: the 5ct Oval Diamond Hidden Halo Engagement Ring lists $2,169.50 for a 5.05ct oval cut stone graded E, VVS2, while this solitaire lists $2,259 for a 5.08ct round cut stone graded E, VS1. The 5ct Radiant Diamond Three Stone Engagement Ring is $2,295 with a 5.05ct radiant cut stone, also E, VS1, in a three-stone setting rather than a cathedral solitaire.

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.

What we liked

  • The ready-to-ship stone data is complete: 5.08ct round cut lab diamond, color E, clarity VS1
  • The notes state that an IGI certificate comes with the ring
  • Made-to-order round stones are listed from 1ct to 10ct, so smaller and larger centers are on offer
  • A single cathedral solitaire design with the price, $2,259, shown plainly

Worth noting

  • The listing gives no band width, no total carat weight and no ring size list
  • Gold colors for the made-to-order metals are not named, only 9K, 14K and 18K solid gold and platinum
  • The listing shows a single price and does not say how it changes for other stones or metals
  • The notes mention very limited inventory

Questions before you buy

What is the ready-to-ship center stone?

A 5.08ct round cut lab diamond, graded E for color and VS1 for clarity, in 18K white gold. The title describes it as a round brilliant.

What stone sizes can be made to order?

The listing gives a round cut lab diamond range of 1ct to 10ct for the made-to-order version, in 9K, 14K or 18K solid gold or platinum.

Does it come with a certificate?

The notes on the listing say it comes with an IGI certificate. They do not say whether that covers made-to-order stones.

Can I return it if I change my mind?

The refunds page gives 30 days from delivery for eligible items and refunds the product value and standard shipping; you pay return shipping unless the item is wrong or defective. Custom orders, special orders, engraved items and altered or tested loose diamonds cannot be returned, and cancellation is possible only within three hours.

How long until it arrives?

The shipping page says ready-to-ship items are dispatched in 1 to 3 business days and arrive in 3 to 7 business days on orders of $500 or more (8 to 25 business days by postal service under $500); the FAQ says 8 to 12 business days of dispatch plus 5 to 15 calendar days. Shipping is free and duties are included for most destinations.

Is an IGI report included?

The store's FAQ says every diamond jewelry piece over $500 comes with an IGI Laboratory Grown Diamond Jewelry Report, which certifies the finished piece rather than only the center stone. Check this listing's text and ask the store to confirm before you pay.

Are lab-grown diamonds real diamonds?

GIA says laboratory-grown diamonds have the same crystal structure as natural diamonds, tightly bonded carbon atoms, and nearly the same chemical, optical and physical properties. By eye the difference can be indistinguishable, but gemological laboratories can detect the different growth history with advanced instruments. They are grown by high-pressure high-temperature (HPHT) or chemical vapor deposition (CVD).

What we couldn’t verify

  • The title calls the stone a round brilliant, but the stone line only says round cut and no cut grade is given.
  • No band width or total carat weight is stated.
  • Independent reviews: none found for Rose Majester on Trustpilot, BBB or Reddit in searches on 19 October 2026.
  • Delivery times and IGI report inclusion differ between the shipping page, the FAQ and individual listings.
  • The factory-direct and 76%-below-retail claims are the store's own; the crossed-out prices are not market prices.
