Pear Shaped Lab-Grown Diamonds: Complete Buying Guide 2026
Quick Answer
Why choose a pear shaped lab-grown diamond?
Pear shapes uniquely elongate the finger, creating an elegant, fashion-forward look. They have 15–20% more face-up surface area than round brilliants of the same carat — more diamond for your money. Their 71 brilliant facets create excellent sparkle. The asymmetrical teardrop shape is distinctive and memorable — unlike any other engagement ring.
📊 Pear shaped lab diamonds show 15-20% larger face-up than equivalent round brilliants. Starting from ~$380 for 0.5ct G/VS2 IGI certified. Bowtie effect is common — always inspect via 360° video.
Why Pear Shaped Diamonds?
The pear shape — sometimes called a teardrop — is a hybrid of the round brilliant and the marquise. It has a rounded bottom and a single pointed top. When worn with the point facing the fingernail, it creates the most dramatically elongating effect of any common engagement ring shape.
- Elongates the finger: The pointed end creates a visual line that makes fingers look longer and more slender
- Largest apparent size: 15–20% more face-up surface than a round of the same carat — you get more visual diamond for your money
- Distinctive: Immediately recognizable and different from the standard round — for buyers who want to stand out
- Brilliant facets: 71 facets deliver excellent sparkle, similar to round brilliants
The Bowtie Effect — What to Watch For
The bowtie is a dark shadow across the center of elongated shapes, caused by light leaking out the sides rather than reflecting back through the top. In pear diamonds, the bowtie runs horizontally across the widest point of the stone.
How to check: Always use 360° HD video to inspect the stone before buying. James Allen provides this for every stone — it's the most reliable way to assess bowtie severity. A slight bowtie is normal and can add character. A strong bowtie is distracting and should be avoided.
Ideal depth: Stay between 58–64% depth. Stones with depth over 66% often have more pronounced bowties.
Orientation & Setting Tips
Most pear diamonds are worn with the point toward the fingernail — this maximizes the elongating effect. The setting must include a V-tip prong on the pointed end to protect it from chipping. The rounded end typically uses 3–4 prongs.
