Our verdict

Suits a buyer who wants a marquise cut lab diamond solitaire in 18K yellow gold that the listing labels ready to ship, with stone grades and an IGI certificate stated. Look elsewhere if you want a different metal or stone size at a known price. The main caveat is a thin spec sheet: no band width and no stone dimensions.

Why 3.6/5: Ready to ship status and a stated IGI certificate lift it. A thin spec sheet and a new store with no independent buyer reviews found hold it back.

The East-West Marquise sets a 1.01ct marquise cut lab diamond, listed as D, VS1, in an 18K yellow gold solitaire with a knife edge band, and the listing labels this version ready to ship at $875. An IGI certificate is stated, along with very limited inventory. For other metals or stones the listing mentions made-to-order versions in 9K, 14K or 18K solid gold or platinum with marquise stones from 1ct to 3ct.

Options and pricing

Two routes appear in the text. Ready to ship: 18K yellow gold with the 1.01ct marquise. Made to order: 9K, 14K or 18K solid gold or platinum with a marquise cut lab diamond from 1ct to 3ct. There are no variant lines, and no price is given for the made-to-order versions. A crossed-out higher price of $1,150.00 is shown, which is the store's own comparison and not a market price.

How it compares

The Marquise Cut Diamond Vintage Engagement Ring lists from $873.40 as a made-to-order marquise ring with a 1.7 mm band and stones of 1.0 to 2.0ct, against $875 here for a ready to ship 1.01ct stone. The 1.5ct Princess Cut Pave Engagement Ring with Lotus Prongs lists $868.50 with a 1.58ct princess cut stone, and the Echoes of 1895 Round Lab Diamond Solitaire Ring in Platinum lists from $894.

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 version names its metal and stone: 18K yellow gold, 1.01ct marquise cut lab diamond, D, VS1
  • An IGI certificate is stated on the listing
  • Made-to-order marquise stones go up to 3ct, in gold or platinum
  • One clear price of $875 for the ready to ship ring

Worth noting

  • No band width or stone length and width are given
  • The listing flags very limited inventory for the ready to ship stone
  • No prices are given for made-to-order versions
  • The east-west orientation is named only in the title

Questions before you buy

Which stone is in the ready to ship East-West Marquise?

A 1.01ct marquise cut lab diamond listed as D, VS1, in 18K yellow gold, with an IGI certificate stated in the listing.

What can be ordered made to order on the East-West Marquise?

The listing names 9K, 14K and 18K solid gold or platinum, with a marquise cut lab diamond from 1ct to 3ct, but gives no prices for these.

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).

  • Delivery times and IGI report inclusion differ between the shipping page, the FAQ and individual listings.
