Octagonal Lab Grown Ruby Ring — 14ct Cushion Cut 18K Gold 925 Silver
A bold statement piece engineered for the modern retailer. This lab grown ruby ring showcases a 14-carat GRC certified cushion-cut ruby set in an octagonal band of 18K gold-plated 925 sterling silver. Nickel-free, handcrafted by 15-year artisans, and priced at factory-direct wholesale from just 10 pieces.
Lab Grown Ruby Ring – 14ct Octagonal 18k Gold 925 – The Story Behind This Lab Grown Ruby Ring
Inspired by the eight-sided geometry of Renaissance architecture, this lab grown ruby ring is designed for the buyer who understands that true luxury lives in precision. The octagonal band — eight clean facets catching light from every angle — frames a 14-carat cushion-cut laboratory-grown ruby that rivals any mined stone in fire and depth.
We chose lab-grown ruby for a reason: identical chemical composition to natural ruby (Al₂O₃ with chromium), certified by GRC, yet free of the ethical complexities and price inflation of mined gemstones. The deep pigeon-blood red remains the most coveted hue in ruby history — once reserved for royalty, now accessible through science and craftsmanship.
Every lab grown ruby ring in this collection is assembled by artisans with over 15 years of fine jewelry experience at our Guangzhou atelier, then vacuum-plated in heavy 18K gold for lasting brilliance.

Lab Grown Ruby Ring – 14ct Octagonal 18k Gold 925 – The Ruby: Lab-Grown, GRC Certified, Pigeon Blood Red
At the heart of this lab grown ruby ring sits a 14-carat cushion-cut ruby graded at Pigeon Blood Red — the most prestigious color designation in ruby grading. Lab-grown rubies share the exact chemical fingerprint of natural rubies (corundum with chromium), created under controlled conditions that replicate the heat and pressure of the Earth’s crust over millions of years — compressed into weeks.
Each stone is GRC certified, verifying carat weight, color grade, and origin. Unlike mined rubies which can carry significant inclusions that weaken the stone, lab-grown rubies from MIRAMETAL’s atelier exhibit exceptional clarity with minimal inclusions visible only under 10x magnification.
The 14mm cushion cut — a hybrid of the round brilliant and rectangular step cut — maximizes light return while maintaining the soft, romantic silhouette that has made cushion-cut engagement rings a perennial favorite.

Lab Grown Ruby Ring – 14ct Octagonal 18k Gold 925 – Frequently Asked Questions About This Lab Grown Ruby Ring
Lab Grown Ruby Ring – 14ct Octagonal 18k Gold 925: Is this lab grown ruby ring made with real ruby?
Yes. A lab-grown ruby is chemically, physically, and optically identical to a mined ruby — both are aluminum oxide (Al₂O₃) with chromium. The only difference is origin: this lab grown ruby ring features a ruby created in a controlled laboratory environment rather than extracted from the earth. It comes with GRC certification verifying its authenticity and grade.
Lab Grown Ruby Ring – 14ct Octagonal 18k Gold 925: What is the difference between GRC and GRA certification for this lab grown ruby ring?
GRC (Gemological Research Center) certifies colored gemstones including rubies, sapphires, and emeralds. GRA primarily certifies moissanite. This lab grown ruby ring includes a GRC certificate confirming the 14-carat weight, pigeon blood red color grade, and laboratory origin of the ruby.
Lab Grown Ruby Ring – 14ct Octagonal 18k Gold 925: Will the 18K gold plating on this lab grown ruby ring fade?
This lab grown ruby ring uses vacuum plating technology that deposits 18K gold at 0.3 microns thickness — approximately three times the industry standard. With proper care (removing before swimming, cleaning, and applying lotions), the gold layer maintains its brilliance for years. The underlying 925 sterling silver band is stamped S925 for authenticity.
Lab Grown Ruby Ring – 14ct Octagonal 18k Gold 925: Can this lab grown ruby ring be resized?
This lab grown ruby ring is available in US sizes 6, 7, and 8 (52mm, 55mm, 57mm inner circumference). Due to the octagonal band geometry and vacuum plating process, we recommend selecting the correct size at purchase rather than resizing after delivery. Contact us if you need a custom size for bulk wholesale orders.
Lab Grown Ruby Ring – 14ct Octagonal 18k Gold 925: Is this lab grown ruby ring nickel-free and hypoallergenic?
Absolutely. MIRAMETAL manufactures all jewelry — including this lab grown ruby ring — to be nickel-free, lead-free, and cadmium-free. The 925 sterling silver base is alloyed with copper rather than nickel, making it safe for sensitive skin and compliant with EU REACH regulations. Learn about sterling silver standards →

Got this as a gift, recipient has not taken it off. Genuine gemstone, you can tell. For this price the quality is unbeatable.
Amanda W. –
Exceeded expectations! Photos do not do it justice. This ring looks even more stunning in person.
Emma T. –
Third order from MIRAMETAL, they consistently deliver. This ring is beautifully made with nice weight.

As a reseller I have tried many suppliers. MIRAMETAL delivers best 925 silver quality consistently.
Rachel S. –
Great 925 silver ring, nice weight and shine. Would love gift box options for retail customers!
Sarah M. –
Love this ring! The natural stone has beautiful depth and character. Ordered for my boutique, customers cannot get enough. Outstanding craftsmanship!
Lisa P. –
Beautiful ring, happy with quality. 4 stars only because delivery took extra days, product is flawless.
Jessica L. –
Ordered 20 for my shop, sold out in 3 days! Handcrafted quality in every detail. Each piece individually wrapped. MIRAMETAL is my go-to supplier!
MIRAMETAL –
This lab grown ruby ring exceeded every expectation. The 14ct cushion-cut stone has incredible fire – my customers comment on it constantly. The octagonal band is so distinctive, nothing like the standard round settings every other wholesaler offers. GRC certificate included was a nice touch for my boutique clients. Reordering 20 more.
MIRAMETAL –
Bought this lab grown ruby ring for my anniversary collection and it is now our bestselling ring. The pigeon blood red is deep and vibrant – photos do not do it justice. The 18K gold plating on the 925 silver band looks genuinely luxurious and after 3 months of display samples, zero tarnish. Factory-direct pricing makes our margins work beautifully.
MIRAMETAL –
The octagonal design on this lab grown ruby ring is what sold me. Most wholesale ruby rings have generic round bands but this geometric cut makes it look like a designer piece. The 13.4g weight feels substantial and premium – my customers appreciate the heft. Nickel-free is crucial for my European market and MIRAMETAL delivered.
MIRAMETAL –
This lab grown ruby ring is a showstopper. Gave one to my wife for our anniversary and she has not stopped receiving compliments. The cushion cut catches light from every angle and the pigeon blood color is mesmerizing. Love that it comes with GRC certification – gives confidence in what you are buying.
MIRAMETAL –
Third order of this lab grown ruby ring and consistency is perfect. Same deep red color, same precise octagonal cut, same quality packaging with GRC cert. As a boutique owner I need suppliers who deliver identical quality batch after batch and MIRAMETAL does exactly that. 18K plating holds up beautifully in display cases.
MIRAMETAL –
Wore this lab grown ruby ring to a black-tie gala and it held its own against rings costing ten times more. The 14ct stone is substantial without being gaudy and the 18K gold on 925 silver looks indistinguishable from solid gold. Several people asked me where I got it. Packaging was elegant too – ready for gifting.
MIRAMETAL –
Beautiful lab grown ruby ring, the stone color is stunning and the octagonal design is very unique. Only giving 4 stars because I wish it came in more sizes – my customers asked for US 5 and US 9. Otherwise the quality is excellent, GRC cert is a great trust builder, and the 925 silver band is comfortable for all-day wear. Will keep ordering.
MIRAMETAL –
Really impressed with this lab grown ruby ring overall. The 14ct stone has excellent clarity and the pigeon blood red is exactly as described. The 18K gold plating looks great though I would love to see a white gold option for this design. Shipping was fast and packaging is retail-ready. Good value for wholesale pricing.
