Out of LisaJewelryUS’s engagement ring lineup, the 1.5ct Colorless VS+ Oval Cut Lab-Grown Diamond Vintage 4-Prong Engagement Ring is one of the pieces that comes up most in bestseller lists. It runs $1,844 at full price, and I’ve seen it discounted to around $1,482 during sale periods. I dug into the specs and the brand’s broader review pattern to see if it earns its spot.
What it’s made of
The center stone is a 1.5 carat oval cut lab-grown diamond, graded colorless with VS+ clarity. That grading combination means the stone should read eye-clean and bright white to the naked eye, without the yellow tint or visible inclusions you’d worry about at a lower grade.
The setting is a vintage-inspired 4-prong design available in rose, yellow, or white gold. The vintage detailing (milgrain edges and a tapered band, based on the style name) is what separates this piece from LisaJewelryUS’s plainer solitaire settings at a similar price.
What buyers are actually saying
LisaJewelryUS as a brand holds around 4.5 stars or better across 100-plus Trustpilot reviews, and the recurring praise lines up with what you’d want from an engagement ring purchase specifically: buyers describe getting a comparable stone to what a traditional jeweler quoted, for a fraction of the price, plus a responsive team that answers questions before you commit to a size or setting.
The honest caveat, since this is a made-to-order piece: some reviewers say production and shipping took longer than the site’s estimate, with less status communication than they wanted in the meantime. That’s a brand-wide pattern, not something specific to this ring, but worth building into your timeline if you’re buying for a proposal date.
Sizing and customization
Like most of the catalog, this ring is built to order, so metal color and ring size are chosen at checkout rather than picked from limited pre-made stock. Production generally takes 12 to 18 working days before it ships, plus a few extra days if you choose a silver or platinum band instead of gold.
Because it’s custom-built, order early. A one-year warranty covers issues like a loose or dislodged center stone after delivery, with repair costs reimbursed up to $100 through a local jeweler.
How it compares
At $1,844 for a 1.5 carat colorless VS+ stone, this ring lands well under what a comparable natural diamond would cost at a traditional jeweler, and it’s in line with or below what other direct-to-consumer lab diamond brands charge for similar specs. The trade-off against a brand like Brilliant Earth is mainly about warranty scope and inventory size rather than stone quality. I laid that out fully in LisaJewelryUS vs. Brilliant Earth.
Should you buy it
If you want a colorless, eye-clean 1.5 carat lab diamond in a vintage-style setting without traditional-jeweler pricing, this ring is a genuinely strong pick. Order with enough lead time before any target date, and double check the current warranty and return terms before you finalize your size.
